Sentinel-6 AMR-C Short Time Critical (STC)

The Sentinel-6 AMR-C Non Time Critical (NTC) product delivers high-precision, fully calibrated brightness temperature data at three microwave frequencies (18.7, 23.8, and 34.0 GHz). Optimised for long-term climate monitoring, the product enables accurate retrieval of wet tropospheric corrections and supports reanalysis and reprocessing applications. Data are structured by satellite passes and made available within 60 days of acquisition in NetCDF format.

The Sentinel-6 AMR-C Near Real-Time (NRT) product provides low-latency measurements of brightness temperatures at 18.7, 23.8, and 34 GHz, acquired with linear polarisation. These data enable rapid estimation of wet tropospheric path delay and atmospheric attenuation corrections for altimetry in near real-time. The product is segmented into 10-minute granules and delivered within three hours of acquisition, supporting operational sea level and weather forecasting systems.

The Sentinel-6 P4 Level 2 Short Time Critical (STC) product provides medium-latency ocean surface data, including sea surface height, wind speed, and wave height, tailored for ocean modelling and assimilation purposes. The data are organized by full satellite passes (pole-to-pole) and are delivered within 36 hours of acquisition. The product is available in NetCDF format and ensures consistent quality for near-operational applications.

The Sentinel-6 P4 Level 1B Short Time Critical (STC) product provides intermediate-latency ocean surface data, including sea surface height, wind speed, and wave height. It is tailored for oceanographic modeling and data assimilation purposes. Data are organized by full satellite passes (pole-to-pole) and are typically delivered within 36 hours of acquisition. The product is provided in NetCDF format and ensures consistent quality for near-operational applications.

The Sentinel-6 P4 Level 1B Non Time Critical (NTC) product delivers the highest quality ocean surface measurements (sea surface height, wind speed, and wave height), designed for climate research and long-term monitoring. The data are organized by full satellite passes and delivered within 60 days of acquisition. The product is provided in NetCDF format and is subject to reprocessing to maintain consistency with evolving standards.

The Sentinel-6 P4 Level 2 Non Time Critical (NTC) product delivers the highest quality ocean surface measurements, including sea surface height, wind speed, and wave height, designed for climate research and long-term monitoring. The data are processed using the most up-to-date algorithms and auxiliary information, organized by full satellite passes, and delivered within 60 days of acquisition. The product is provided in NetCDF format and is subject to regular reprocessing to maintain consistency with evolving processing standards.
