RAMSES II: JPSS-1 ATMS Monthly Gridded Atmospheric Profiles

Sounder SIPS: JPSS-1 ATMS Level 3 RAMSES2 Standard Gridded Monthly V3 at GES DISC is a NASA dataset containing geophysical parameters retrieved from NOAA-20 satellite microwave sounder observations. The RAMSES II algorithm processes data from the 22-channel Advanced Technology Microwave Sounder (ATMS) to produce all-weather retrievals of temperature profiles, water in all phases, and surface properties. Data is provided as a monthly, one-degree latitude by one-degree longitude gridded product with quality control flags for each variable.

Use Cases

• Analyzing global temperature profiles based on microwave-only retrievals.
• Studying atmospheric water vapor and precipitation patterns from all-weather satellite data.
• Monitoring sea surface and land surface skin temperatures from gridded satellite observations.
• Validating climate models against long-term, gridded microwave sounding records.

Strengths

• Provides all-weather retrievals as the algorithm lacks a cloud clearing process.
• Includes quality control values (0=best, 1=good, 2=don't use) for each variable.
• Data is derived from a cross-track scanner with 22 channels across 23 GHz to 183 GHz.
• Dataset is hosted on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating importance and curation.

Limitations

• Specific column names, row counts, and file sizes are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without explicit details.
• Update dates conflict; one source lists a future date (2026-04-09), suggesting potential metadata errors.
