Sentinel-6 P4 Level 2 Non Time Critical (NTC)

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 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 2 Near Real-Time (NRT) product provides low-latency, operational-quality ocean surface data, including sea surface height, wind speed, and wave height measurements. The data are segmented into 10-minute granules per ground station pass and are delivered within three hours of acquisition. The product is optimized for use by meteorological and oceanographic agencies and is provided in NetCDF and BUFR formats.

The Sentinel-6 P4 Level 1B Near Real-Time (NRT) product provides low-latency, operational-quality ocean surface data, including sea surface height, wind speed, and wave height. The data are segmented into 10-minute granules per ground station pass and delivered within three hours of acquisition. The product is provided in NetCDF and BUFR formats.

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.
