SatCORPS CERES GEO: Hourly Cloud and Radiation Properties from Meteosat-11

CER_GEO_Ed4_MET11_NH_V01.2 is a NASA Langley Research Center data product providing hourly cloud microphysical and radiation properties derived from the SEVIRI instrument on the Meteosat-11 geostationary satellite. The dataset supports the CERES project, merging geostationary data to estimate fluxes between CERES instrument measurements and account for the diurnal cycle. Observations are at a 4 km resolution at nadir, sub-sampled to 8 km, and are delivered in hourly netCDF-4 files.

Use Cases

• Modeling the Earth's diurnal radiation cycle based on hourly cloud property estimates.
• Analyzing cloud microphysical properties over the Northern Hemisphere based on SEVIRI instrument data.
• Validating and supplementing CERES broadband radiometric measurements with geostationary-derived fluxes.
• Studying temporal changes in atmospheric radiation using a long-term satellite record.

Strengths

• Data is derived from the operational Meteosat-11 satellite, a key platform for geostationary observation.
• Provides hourly temporal resolution to capture the diurnal cycle.
• Supports a long-term NASA CERES mission with heritage from the ERBE experiment.
• Observations have a spatial resolution of 4 km at nadir.

Limitations

• Data collection is noted as 'in progress', suggesting the dataset may be incomplete or provisional.
• Row count and total temporal coverage are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
