Indonesia Floods: Flood Proxy Map, May 2020

# ARIA-SG Flood Proxy Map: Malaysia, Floods, 7 Jan 2021, v0.7 Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) from 1 Jan 2020 to 7 Jan 2021. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech. Data processing used an AWS Open Dataset of Copernicus Sentinel-1 data for the Asia region (https://registry.opendata.aws/sentinel1-slc-seasia-pds). **More map details and files:** **More map details and files:**

# ARIA-SG Flood Proxy Map: India Floods, 30 Sep 2019, v0.1 Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (21 May) and during (30 Sep) the event. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech. **More map details and files:**

# ARIA-SG Flood Proxy Map: Laos Floods, 6 Sep 2019, v0.1 Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (3 Apr) and during (6 Sep) the event. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS), using the ARIA-SG system originally developed by NASA-JPL and Caltech. Data processing used an AWS Open Dataset of Copernicus Sentinel-1 data for the Asia region (https://registry.opendata.aws/sentinel1-slc-seasia-pds). **More map details and files:**

# ARIA-SG Flood Proxy Map: Philippines, Typhoon Tisoy, 7 Dec 2019, v0.1 Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (23 Apr) and during (7 Dec) the event. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech.

# EOS-RS Flood Proxy Map: Malaysia, Floods, Dec 2021, v0.4 The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Flood Proxy Map (FPM) depicting areas that are likely flooded in north and central Peninsular Malaysia due to heavy rains. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (9 Dec 2021) and during (21 Dec 2021) the event. The image covers an area indicated by the large white polygon. Each light blue pixel measures about 30 meters across. This flood proxy map should be used as a guide to identify areas that are likely flooded, and is less reliable over urban and vegetated areas. Sentinel-1 data were accessed through the Copernicus Open Hub and AWS Open Dataset of Copernicus Sentinel-1 data for the Asia region (https://registry.opendata.aws/sentinel1-slc-seasia-pds). The product contains modified Copernicus Sentinel data (2021), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), using the Advanced Rapid Imaging and Analysis (ARIA) system originally developed at NASA's Jet Propulsion Laboratory, California Institute of Technology, and modified at EOS-RS. **More map details and files:** **More map details and files:**

# ARIA Flood Proxy Map: India, Bangladesh, 2019 Floods This map shows areas that are likely flooded in northeast India and Bangladesh due to heavy rains brought by the monsoon season, shown by light blue pixels of 30 m (Copernicus Sentinel-1) and 25 m (ALOS-2) pixel size, and is a preliminary result. The map extents are indicated with red and yellow polygons. This map should be used as a guidance to identify areas that are likely flooded, and may be less reliable over urban and vegetated areas. Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (15 May) and during (14 Jul) the event, and by the ALOS-2 satellite operated by the Japanese Aerospace Exploration Agency (JAXA) before (25 Mar) and during (15 Jul) the event. Analysed by the ARIA-SG team at the Earth Observatory of Singapore in collaboration with NASA/JPL-Caltech. For more information, please visit **More map details and files:**
