GPM ATMS on NOAA-21 (GPROF) Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25

GPM_3GPROFNOAA21ATMS_DAY Version 07 provides global gridded daily precipitation averages from the NOAA-21 satellite's ATMS sensor. The data is based on retrievals from high-quality microwave sensors sensitive to liquid and ice-phase precipitation hydrometeors. This Level 3 product is produced by NASA's GES DISC and was last updated in March 2026.

Use Cases

• Climate trend analysis based on global gridded precipitation averages
• Atmospheric hydrometeor research based on microwave sensor retrievals
• Satellite data validation and intercomparison based on high-quality sensor inputs
• Hydrological modeling based on daily precipitation estimates

Strengths

• Version 07 is the current and supported version, superseding older data.
• Data is based on retrievals from high-quality microwave sensors.
• Provides global coverage at a 0.25 degree x 0.25 degree spatial resolution.
• Produced by the National Aeronautics and Space Administration (NASA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
