Sentinel-6 P4 Level 2 Short Time Critical (STC)

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 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.

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.
