CERES Terra Satellite Hourly Radiative Fluxes at 1-Degree Resolution, 2018-2022

CERES Terra Edition4A provides hourly computed radiative fluxes on a global 1-degree grid from January 2018 to December 2022. The National Aeronautics and Space Administration produced this Level 3 data product using the Fu-Liou radiative transfer model with four atmospheric assumptions. It includes instantaneous averages of top-of-atmosphere, within-atmosphere, and surface fluxes derived from CERES instrument broadband channel measurements.

Use Cases

• Modeling Earth's radiative energy budget based on computed top-of-atmosphere, within-atmosphere, and surface fluxes
• Analyzing diurnal cycles of atmospheric radiation based on hourly temporal resolution
• Studying cloud and aerosol radiative effects based on clear-sky and total-sky flux assumptions
• Validating climate models based on satellite-derived broadband radiometric measurements

Strengths

• Data processed for a five-year period from January 1, 2018, to December 31, 2022
• Provides fluxes at multiple atmospheric levels (0.01-hPa, 850-, 500-, 200-, and 70-hPa) and the surface
• Uples four specific atmospheric assumptions (Total-sky, clear-sky, pristine, total-sky no aerosol) in the radiative model

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect temporal bias inherent to the specific 2018-2022 satellite observation period
• Row count is unknown, which may limit suitability assessment
