CERES and GEO-Enhanced TOA, Within-Atmosphere and Surface Fluxes, Clouds and Aerosols Dail

CERES and GEO-Enhanced TOA, Within-Atmosphere and Surface Fluxes, Clouds and Aerosols Daily Terra-Aqua Edition4A provides daily, global-scale data on Earth's energy budget. NASA's product combines measurements from CERES and MODIS instruments on the Terra and Aqua satellites with geostationary satellite data to model diurnal variability. It offers computed fluxes for all-sky, clear-sky, and aerosol-free conditions at a 1-degree spatial resolution.

Use Cases

• Modeling global radiative forcing based on computed top-of-atmosphere, within-atmosphere, and surface fluxes.
• Analyzing cloud radiative effects using provided cloud properties from MODIS and geostationary satellites.
• Studying aerosol impacts on atmospheric energy transfer using pristine and all-sky without aerosol condition data.
• Validating climate models with temporally interpolated, CERES-calibrated flux observations.

Strengths

• Data collection is described as ongoing, providing a continuous temporal record.
• Product integrates multiple instrument sources (CERES, MODIS, GEO) for enhanced diurnal sampling.
• Fluxes are provided for specific spectral regions: longwave, shortwave, and window.
• Uses a normalization technique to ensure consistency between CERES and geostationary satellite flux measurements.

Limitations

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