GPM_BASETRMMTMI: Raw TRMM Microwave Imager Satellite Data

GPM_BASETRMMTMI contains unaltered raw data from the TRMM Microwave Imager (TMI) instrument aboard the TRMM satellite. The product repackages raw binary CCSDS packets into HDF5 format and geolocates the sample data. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Develop calibration algorithms based on raw instrument counts.
• Reprocess or validate geolocation for TRMM TMI observations.
• Study raw signal characteristics of microwave imagery for precipitation and water vapor.

Strengths

• Contains raw, unaltered instrument counts directly from satellite packets.
• Data is repackaged into the modern HDF5 format from legacy binary CCSDS packets.
• Product is geolocated, providing spatial reference for the raw samples.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data contains no calibration or interpretation, requiring significant expertise to use.
