Overview Carotenoid Content Index (Car) from the NASA Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Ocean Color Instrument (OCI). Car describes the canopy content of carotenoids in terrestrial vegetation. Car is calculated as ((1/R495)-(1/R705))*R800, where R495, R705, and R800 are the surface reflectance at 495, 705 and 800 nanometers (nm), respectively (Gitelson et al. 2002). Data provided as global, 8-day averages mapped to a standard, equal-angle, latitude-longitude grid of 0.02 degrees, which equates to ~2 kilometers (km) at the equator. Data has been corrected for atmospheric scattering and absorption. Pixels with no data values are masked (excluded) due to presence of water, cloud cover, or other features marked by quality control flags as described below. Data Layer Summary Name, units Carotenoid Content Index (Car) Measure of terrestrial canopy carotenoid content, a phytosynthetic and photoprotective pigment. Car is unitless. Spatial resolution 2 km2 Level-3, mapped to standard grid, global coverage Time Resolution 8 day average Each pixel represents an average of the valid, daily values observed within that grid element during the 8-day interval (approx 1 week). Note: 8 day average data layer is calculated from daily, "refined" (archive-quality) Level 3 PACE Car products available here from NASA Earthdata in NetCDF format. Earthdata account required. Each NetCDF file includes all 10 PACE vegetation indexes, including Car. Data Version Version 3.1 Data versions change as improved calibration, validation, algorithm refinements, etc are applied over time. See Version 3.1 Release Notes for details. Latency ~1 month This imagery service provides “refined” (archive-quality) PACE data products from March 2024-present, which have an approx 1 month latency. Note: Lower latency “near real time (NRT)” Level 3 PACE Car products available daily from NASA Earthdata at this link in NetCDF format. Latency typically Earthdataaccount required. Each NetCDF file includes all 10 PACE vegetation indexes, including Car. Intended Use: What can I do with this layer? There are three major classes of plant pigments: chlorophylls, carotenoids, and anthocyanins. Car provides information on changes in vegetation carotenoid content and photophysiological status. Carotenoids are structural components of the photosynthetic antenna and reaction center complexes and serve both photosynthetic and photoprotective functions (Blackburn 2007). The time (8 day average) and space (2 km2) resolution of this data layer enables weekly to seasonal and annual insight at local to global scales.   Limitations of Use: What should I know about the data? Data Status (Maturity): This product is provisional, which means that product results have been reviewed and are in family with heritage data products or other basis of expectation, but have not yet been extensively validated and so may still contain significant errors. Data layer is sufficient for qualitative determinations of product fitness-for-purpose, for testing by operational users, and may be suitable for scientific publication. Data Masking: This is a Level 3, globally-binned product from NASA’s Ocean Biology Processing Group (OBPG). By default, OBPG Level 3 data values are masked (value is set to null, or no data) according to a standard set of quality control parameters. Please see Level 3 Algorithm Usage Constraints for masking parameter details. Algorithm Theoretical Basis Document (ATBD): See ATBD for algorithm details including scientific theory, calculations, etc. https://doi.org/10.5067/8L77O0Y8GHV8.   Where do I go with further questions?

PACE is a comprehensive Earth System mission, delivering all new, space-based information on the health and diversity of aquatic and terrestrial life (algae, plants), aerosol properties & modes (e.g. smoke, dust), cloud types, and more.  The Ocean Color Instrument (OCI), PACE's primary sensor, is a hyperspectral (5 nm resolution) imaging spectrometer that measures properties of light from the ultraviolet (UV, 340 nm) through visible and near infrared (NIR, 895 nm) portions of the electromagnetic spectrum in 1.25 to 2.5 nm steps, plus 7 shortwave infrared (SWIR) bands (Werdell et al. 2019). Observations from OCI are moderate spatial resolution (1.2 km2), enabling a relatively frequent revisit time of 1-2 days. This combination of continuous, global coverage and spectral capabilities is unmatched by any other satellite platform, public or private. PACE benefits society by expanding our foundational knowledge of Earth and enabling novel, space-based science and applications tools across water resources (e.g. fisheries), air quality, land monitoring & management, and more.   Terrestrial Remote Sensing from an Ocean Color Sensor? Designed and optimized to operate across a broad dynamic range, from the dark target of the ocean to bright, highly reflective cloud tops, PACE’s OCI also collects surface reflectance data from the world's terrestrial environments across 122 bands, resolving spectral properties of the Earth more finely than previous multispectral missions could achieve. Work thus far has demonstrated viability of OCI’s land data products for terrestrial investigations (Caplan et al. 2025). OCI’s coverage and capabilities enable provision of both novel, hyperspectral-enabled land observations as well as maintenance and extension of certain historical multispectral data records. Advanced vegetation indexes (VIs) enabled by OCI’s narrow-wavelength surface reflectance measurements provide continuous, synoptic insights into foliar pigment amounts (chlorophylls, carotenoids, and anthocyanins), water content, and photosynthetic light use efficiency across the globe each day. Heritage VIs (e.g., normalized difference vegetation index, NDVI; reviewed in Huang et al. 2021) can also be calculated by aggregating (averaging) OCI’s narrow bandwidths across ranges that approximate the multi-spectral, broadband reflectances of instruments such as MODIS, see the Mathematical Theory section of the ATBD for details. See the full list of heritage and hyperspectral-enabled VIs produced by PACE here.   What other PACE data layers are available? This data layer is 1 of 11 PACE products initially selected for the Living Atlas catalog from the mission’s comprehensive aquatic, atmospheric, and terrestrial product catalog. Click here to view all 11 PACE Living Atlas imagery services.

NOTICE: This is a beta service without operational support. It will be expanded in a future release to cover the historical and ongoing temporal record of ATL08. This map service is a GIS-ready version of the ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 7 (ATL08) data set. ATL08 provides along-track estimates of terrain height, canopy height, and canopy cover, as well as beam and reference parameters, acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory. The complete ATL08 source data formatted as HDF5 files are available from the NASA NSIDC DAAC, along with user documentation and resources.  This beta map service displays ATL08 data as a series of georeferenced points arranged in linear "ground tracks." These ground tracks represent the 100 m land segments output from the algorithms applied to the photon return data collected by the ATLAS instrument as ICESat-2 orbits the Earth over its 91-day repeat cycle. As shown in the figure below, the ATLAS instrument measures data along six ground tracks (GT) arranged in 3 pairs (one "weak" beam and one "strong" beam in each pair). Each GT is numbered according to the relative location of the laser that generates it, along with L (left) or R (right). GT1L and GT1R form pair one, GT2L and GT2R form pair two, and GT3L and GT3R form pair three, with GT1L on the far left and GT3R on the far right relative to the satellite flight direction. Left/right beams within each pair are approximately 90 m apart with the pairs separated by 3.3 km in the across-track direction. The along-track laser spacing is ~70 cm. Algorithms produce parameters representing 100 m land segments in the along-track direction for each beam. Image source: Smith et al., 2019 - https://doi.org/10.1016/j.rse.2019.111352 Additional information about the ATLAS instrument, ICESat-2 satellite, and ground track naming conventions and geometry can be found in Appendix A of the ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 7 User Guide. Available Parameters A selection of "core" parameters was chosen from the full suite of parameters available in the complete ATL08 source data. A list of the available core parameters, including canopy and terrain height, can be found in the technical specification document. When accessing the data through the web-based Map Viewer, these parameters are visible as a popup window when a single data point is selected. Note: where canopy data is absent, these parameters will not have values. Spatial Coverages and Resolution Spatial coverage is nearly global (approximately 88°N to 88°S). However, data are not produced for orbital segments that cross open ocean only (i.e., do not cross a land surface). The canopy and ground surfaces are processed in fixed 100 m data segments, which typically contain more than 100 signal photons but may in some cases contain less. Temporal Coverage and Resolution  9 December 2025 to 11 March 2026 Data are re-acquired along each of ATLAS/ICESat-2's 1,387 reference ground track every 91 days. This beta service presents a single 91-day satellite repeat cycle. Recommended Data Access Guidelines If you would like to access these data using ArcGIS Pro or QGIS, we recommend using the Feature Service, rather than the Map Service. When accessing the Map Service data using the web-based Map Viewer, we suggest the following settings be applied:Time Slider: Set temporal range to the full 91-day extent Visibility Range: Within the map properties window, ensure the current map scale (black triangle) is within the selected visibility range Recommended settings when using Map Viewer.  For in-depth data users who wish to perform customized data processing, we suggest using the full ATL08 source data, available from the NASA NSIDC DAAC as ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 7.

Update Frequency:Twice a day Summary:The global Landslide Hazard Assessment for Situational Awareness (LHASA) model was developed to inform a wide range of users about landslide hazards. LHASA version 2.1 uses machine learning to show where and when landslides are most probable. Suggested Use:LHASA 2.1 was created to enable global monitoring of landslide hazard and is not a substitute for local site investigations. Red indicates high hazard and blue indicates low hazard.  LHASA nowcast "today": This map shows the relative probability of landslide occurrence today, based on rainfall estimates from GPM and forecasts from GEOS-FP.

Retirement Notice: This item is in mature support as of February 2026 and will retire in December 2027. A new version of this item is available for your use. Esri recommends updating your maps and apps to use the new version. This layer shows total population count by sex and age group. This is shown by tract, county, and state boundaries. This service is updated annually to contain the most currently released American Community Survey (ACS) 5-year data, and contains estimates and margins of error. There are also additional calculated attributes related to this topic, which can be mapped or used within analysis.   This layer is symbolized to show the percentage of the population that are considered dependent (ages 65+ and Vintage: 2019-2023ACS Table(s): B01001Data downloaded from: Census Bureau's API for American Community Survey Date of API call: December 12, 2024National Figures: data.census.gov  The United States Census Bureau's American Community Survey (ACS):About the Survey   Geography & ACS   Technical Documentation   News & Updates   This ready-to-use layer can be used within ArcGIS Pro, ArcGIS Online, its configurable apps, dashboards, Story Maps, custom apps, and mobile apps. Data can also be exported for offline workflows. For more information about ACS layers, visit the FAQ. Please cite the Census and ACS when using this data. Data Note from the Census:  Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data).  The effect of nonsampling error is not represented in these tables. Data Processing Notes:This layer is updated automatically when the most current vintage of ACS data is released each year, usually in December. The layer always contains the latest available ACS 5-year estimates. It is updated annually within days of the Census Bureau's release schedule. Click here to learn more about ACS data releases.   Boundaries come from the US Census TIGER geodatabases, specifically, the National Sub-State Geography Database (named tlgdb_(year)_a_us_substategeo.gdb). Boundaries are updated at the same time as the data updates (annually), and the boundary vintage appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines erased for cartographic and mapping purposes. For census tracts, the water cutouts are derived from a subset of the 2020 Areal Hydrography boundaries offered by TIGER. Water bodies and rivers which are 50 million square meters or larger (mid to large sized water bodies) are erased from the tract level boundaries, as well as additional important features. For state and county boundaries, the water and coastlines are derived from the coastlines of the 2023 500k TIGER Cartographic Boundary Shapefiles. These are erased to more accurately portray the coastlines and Great Lakes. The original AWATER and ALAND fields are still available as attributes within the data table (units are square meters). The States layer contains 52 records - all US states, Washington D.C., and Puerto Rico Census tracts with no population that occur in areas of water, such as oceans, are removed from this data service (Census Tracts beginning with 99). Percentages and derived counts, and associated margins of error, are calculated values (that can be identified by the "_calc_" stub in the field name), and abide by the specifications defined by the American Community Survey. Field alias names were created based on the Table Shells file available from the American Community Survey Summary File Documentation page.   Negative values (e.g., -4444...) have been set to null, with the exception of -5555... which has been set to zero. These negative values exist in the raw API data to indicate the following situations:The margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate. Either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.   The median falls in the lowest interval of an open-ended distribution, or in the upper interval of an open-ended distribution. A statistical test is not appropriate. The estimate is controlled. A statistical test for sampling variability is not appropriate.   The data for this geographic area cannot be displayed because the number of sample cases is too small.

Overview and Intended Use GPM IMERG Early Precipitation Rate L3 V07 (GPM IMERG Early Precipitation L3 Half Hourly 0.1 degree x 0.1 degree V07 (GPM_3IMERGHHE 07)) is an image service derived from the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (GPM) Early dataset. This image service is intended for visualizing, mapping, and analyzing near-real-time global precipitation rate estimates from the GPM IMERG Early dataset at 30-minute temporal resolution and 0.1° x 0.1° spatial resolution. To access the REST endpoint for the service, input the URL into a browser or select View just above the URL.   Limitations of Use: The image service shows precipitation rate (mm/hr), approximately four hours after observation. NoData values, and values less than 0.03 mm/hr (the current threshold value for the IMERG algorithm) have been removed. The image service provides global coverage with a temporal span from 06/01/2000 0:00 UTC to present at 30-minute intervals.  The service is updated every three hours to incorporate the new granules.   IMERG is an algorithm that estimates precipitation rate from multiple passive microwave sensors in the GPM constellation, the GPM Dual-Frequency Radar, and infrared (IR) sensors mounted on geostationary satellites. Currently, the near-real-time Early estimates have no concluding calibration. Briefly describing the Early Run, the input precipitation estimates computed from the various satellite passive microwave sensors are intercalibrated to the Combined Radar-Radiometer Algorithm (CORRA) product (because it is presumed to be the best snapshot Tropical Rainfall Measuring Mission (TRMM)/GPM estimate after adjustment to the monthly Global Precipitation Climatology Project Satellite-Gauge (GPCP SG)), then "forward morphed" and combined with microwave precipitation-calibrated geo-IR fields to provide half-hourly precipitation estimates on a 0.1°x0.1° (roughly 10x10 km) grid over the globe. Precipitation phase is computed using analyses of surface temperature, humidity, and pressure.   Dataset at a Glance Shortname: GPM_3IMERGHHE DOI: 10.5067/GPM/IMERG/3B-HH-E/07 Version: 07 Coverage: -180.0,-90.0,180.0,90.0 Temporal Coverage: 2000-06-01 to Present Data Resolution Spatial: 0.1 ° x 0.1 ° Temporal: 30 minutes   Symbology The default symbology in the Map Viewer may be changed to accommodate other color schemes using the settings in the Image Display panel from the layer settings menu.

Ensure that pop-ups are enabled to view pixel values (select Modify Map first).   Temporal Coverage The source dataset is in UTC time but the service is displayed in the Map Viewer in local time. The data is available in 30-minute intervals, and the map visualization may be modified by opening the Time Slider Settings menu from the icon on the time slider bar. The total temporal coverage may be limited to the desired range and the time interval may also be changed. The options in the time interval units are based on the total time range input, so a shorter time range will enable shorter time units to be selected from the time interval drop-down menu. If the time settings are set to more than 30-minute intervals, the first time slice in the time interval is visible.   Portal Options Select Modify Map to customize the layer visualization. More information about the image service capabilities may be found in the REST endpoint. In the portal, the basemap may be changed by selecting the desired option from the Basemap menu.

GPM IMERG Final precipitation rate(GES DISC Dataset: GPM IMERG Final Precipitation L3 Half Hourly 0.1 degree x 0.1 degree V07 (GPM_3IMERGHH 07))is derived from the Integrated Multi SatellitE Retrievals for GPM (Global Precipitation Measurement) algorithm. Precipitation rate measurements are taken from multiple satellite based passive microwave sensors in the GPM constellation. The Final Run IMERG data product is distinct in that it combines data from ground sources and satellite-based observations to provide research quality precipitation rate data. Precipitation rate is depicted in mm/hr in 30-minute intervals, beginning on January 1, 1998. The "Final", satellite-gauge product is available ~3.5 months after the observation month, and includes both forward and backward morphing and monthly gauge analyses. In the post-real-time Final Run, the multi-satellite half-hourly estimates are adjusted so that they sum to the Final Run monthly satellite-gauge combination. Briefly describing the Final Run, the input precipitation estimates computed from the various satellite passive microwave sensors are inter-calibrated to the Combined Radar-Radiometer Algorithm (CORRA) product (because it is presumed to be the best snapshot Tropical Rainfall Measuring Mission (TRMM)/GPM estimate after adjustment to the monthly Global Precipitation Climatology Project Satellite-Gauge (GPCP SG)), then "forward/backward morphed" and combined with microwave precipitation-calibrated geo-IR fields, and adjusted with seasonal GPCP SG surface precipitation data to provide half-hourly and monthly precipitation estimates.   Dataset at a Glance Shortname: GPM_3IMERGHH DOI: 10.5067/GPM/IMERG/3B-HH/07 Version: 07 Coverage: -180.0,-90.0,180.0,90.0 Temporal Coverage: 1998-01-01 to Present Data Resolution Spatial: 0.1 ° x 0.1 ° Temporal: 30 minutes   Symbology The default symbology in the Web Map Viewer may be changed to accommodate other color schemes using the settings in the Image Display panel from the layer settings menu.
