CERES SYN1deg-Day Terra Edition4A: Daily Global Radiative Fluxes and Cloud Properties

Global daily data on top-of-atmosphere, within-atmosphere, and surface radiative fluxes, alongside cloud and aerosol properties, collected by NASA's CERES instruments on Terra and geostationary satellites. The product provides parameters on a 1-degree regional spatial scale and daily temporal resolution, with computations for all-sky, clear-sky, and aerosol conditions. It is produced by the National Aeronautics and Space Administration using the Langley Fu-Liou radiative transfer model and data normalized between CERES and geostationary satellite observations.

Use Cases

• Modeling Earth's radiative energy budget based on provided TOA, in-atmosphere, and surface fluxes.
• Analyzing cloud property variability and impact on climate based on MODIS and GEO-derived cloud parameters.
• Studying aerosol optical depth and its radiative effects based on aerosol condition computations.
• Investigating diurnal cycles of radiative fluxes based on GEO-enhanced hourly sampling methodology.
• Validating climate models using observed, temporally interpolated, and calculated flux data.

Strengths

• Data collection is complete, providing a finalized historical record.
• Fluxes are provided for longwave, shortwave, and window regions under multiple sky conditions.
• Uses a normalization technique to ensure consistency between CERES and geostationary satellite fluxes.
• Parameters are provided on a daily temporal resolution and 1-degree regional spatial scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description recommends using this product in conjunction with a complementary Aqua-MODIS product for science-quality research.
