CERES ERBE-like Instantaneous TOA Estimates from TRMM Satellite

CERES ERBE-like Instantaneous TOA Estimates TRMM PFM Edition2 is a Clouds and the Earth's Radiant Energy System (CERES) Earth Radiation Budget Experiment (ERBE)-like data product. It provides a 24-hour, single-satellite, instantaneous view of scanner fluxes at the top-of-atmosphere (TOA) from the Tropical Rainfall Measuring Mission (TRMM) proto flight model (PFM) instrument. The data collection is complete and includes total, shortwave, longwave, and window channel radiometric data organized into 3.3-second scan records.

Use Cases

• Model Earth's radiation budget based on instantaneous top-of-atmosphere scanner fluxes.
• Analyze shortwave and longwave radiative energy distribution based on unfiltered radiance values.
• Identify atmospheric scenes for climate studies based on ERBE scene identification data.
• Validate climate models using satellite-derived top-of-atmosphere energy estimates.

Strengths

• Data collection is complete, providing a finalized dataset.
• Includes radiometric data from four distinct channels: total, shortwave, longwave, and window.
• Organized into precise temporal records based on CERES 3.3-second scans.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific TRMM satellite mission period.
