GPM_3GPROFNOAA21ATMS: Global Monthly Precipitation Averages from NOAA-21 Satellite

Global gridded monthly precipitation averages derived from the NOAA-21 satellite's Advanced Technology Microwave Sounder (ATMS). The dataset is produced by NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) using Version 07 retrieval algorithms. It provides climate-scale precipitation estimates based on microwave sensor data sensitive to liquid and ice-phase hydrometeors.

Use Cases

• Climate trend analysis based on global monthly precipitation averages
• Atmospheric hydrometeor research based on microwave sensor retrievals sensitive to liquid and ice
• Validation of climate models based on satellite-derived gridded precipitation data

Strengths

• Data is from the current Version 07 of the retrieval algorithm
• Based on high-quality microwave sensors from the NOAA-21 satellite
• Provides global coverage at a 0.25-degree spatial resolution

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
