    • Sounder SIPS: Suomi NPP ATMS Level 2 RAMSES2 Standard: Atmosphere, precipitation and surface geophysical state, V3 (SNDRSNML2RMS ) at GES DISC

    Metadata Updated: September 18, 2025

    This level 2 product is generated by the RAMSES (Retrieval Algorithm for Microwave Sounders in Earth Science) II algorithm.The RAMSES II algorithm is a microwave only retrieval algorithm using observations from the Suomi-National Polar-orbiting Partnership (NPP) Advanced Technology Microwave Sounder (ATMS) instrument. The ATMS instrument used for this product is a cross-track scanner with 22 channels in spectral bands from 23 GHz through 183 GHz. The RAMSES II Level-2 retrieval products contain a variety of geophysical parameters retrieved from ATMS measurements, including profiles of temperature, water in all phases as well as surface properties for six minutes of instrument observation at a time. The RAMSES II algorithm doesn't have a cloud clearing process and produces all weather retrievalA level 2 granule has been set as 6 minutes of data. There are 240 granules per day, with an orbit repeat cycle of approximately 16 day.
