CERES SSF1deg: Daily TOA Fluxes, Clouds, and Aerosols on a 1-degree Grid

Global daily averages of top-of-atmosphere radiative fluxes, cloud properties, and aerosols on a 1-degree latitude and longitude grid. The data is produced by NASA's CERES instruments aboard satellites like Terra, Aqua, Suomi NPP, and JPSS-1. It provides measurements for clear-sky and all-sky conditions across longwave, shortwave, and window wavelength bands.

Use Cases

• Model Earth's radiative energy budget based on daily averaged TOA fluxes.
• Analyze cloud layer properties based on stratification into four atmospheric pressure layers.
• Study aerosol impacts on atmospheric radiation based on co-located imager aerosol values.
• Validate climate model outputs based on temporally interpolated CERES measurements.
• Track solar irradiance variability based on SORCE and TSI data.

Strengths

• Data is derived from multiple CERES instruments launched on flagship satellites like Terra and Aqua.
• Cloud properties are stratified into four atmospheric layers and averaged for day-only and 24-hour periods.
• TOA fluxes are provided for clear-sky and all-sky conditions across three broadband wavelength bands.

Limitations

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