TRMM_3G25: Gridded Orbital Spectral Latent Heating Profiles

TRMM PR Gridded Orbital Spectral Latent Heating Profiles L3 1.5 hours 0.5 degree x 0.5 degree V7 (TRMM_3G25) is a NASA dataset providing gridded latent heating, Q1-QR, and Q2 profiles derived from Precipitation Radar (PR) rain data. The data is produced at a 0.5-degree spatial resolution, with each granule representing one satellite orbit. It is hosted by the NASA GES DISC.

Use Cases

• Analyzing latent heating profiles to understand energy release in tropical convection.
• Studying cloud dynamics and precipitation processes using Q1-QR and Q2 atmospheric profiles.
• Model validation and data assimilation for weather and climate models based on gridded orbital data.
• Investigating spatial patterns of atmospheric heating at a 0.5-degree resolution.

Strengths

• Data is produced by NASA, a leading authority in Earth science observation.
• Provides a specific 0.5-degree x 0.5-degree spatial resolution for detailed geospatial analysis.
• Cross-platform presence on Data.gov and NASA EarthData signals established importance and accessibility.

Limitations

• Column names and detailed schema are not provided in any source, limiting precise understanding of data structure.
• Metadata conflicts exist: the last update date is listed as 2026-03-12 on Data.gov but 2015-04-01 on NASA EarthData, creating uncertainty about data freshness.
• Granule size is limited to one orbit, which may constrain temporal analysis for longer-term studies.
