Sounder SIPS: Suomi NPP ATMS Level 3 RAMSES2 Standard Gridded Daily V3 at GES DISC

This level 3 daily product is generated from 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 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. The RAMSES II algorithm doesn't have a cloud clearing process and produces all weather retrieval This daily one degree latitude by one degree longitude level-3 product starts with level-2 retrieval products with QC values of 0 (best), 1 (good), and 2 (don't use) which are provided for each variable.
