CERES SYN1deg: Earth Radiation, Cloud, and Aerosol Data at 1-Hourly Monthly Resolution

CERES and GEO-enhanced data provides monthly-averaged one-hourly parameters on a 1-degree regional spatial scale. The product combines observations from CERES instruments on Terra and Suomi NPP satellites with geostationary satellite data to model radiative flux variability. It was produced by NASA using the Langley Fu-Liou radiative transfer model and data collection for this edition is complete.

Use Cases

• Modeling Earth's radiative energy budget based on computed top-of-atmosphere, within-atmosphere, and surface fluxes.
• Analyzing cloud property impacts on climate based on MODIS-derived and GEO-enhanced cloud data.
• Studying aerosol effects on atmospheric radiation based on parameters for pristine and all-sky without aerosol conditions.
• Investigating diurnal variability of solar and thermal radiation based on 1-hourly temporal resolution data.
• Validating climate models based on CERES-observed fluxes normalized with geostationary satellite data.

Strengths

• Data collection is complete for this Edition1A product.
• Parameters are provided at a monthly-averaged one-hourly temporal resolution.
• Fluxes are provided for clear-sky and all-sky conditions in long-wave, shortwave, and window regions.
• Product uses a normalization technique to ensure consistency between CERES and GEO top-of-atmosphere fluxes.

Limitations

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