Description
CERES BDS and SYN1deg data products provide geolocated, calibrated radiance measurements and derived top-of-atmosphere radiative fluxes, cloud, and aerosol properties. Data is collected by CERES instruments on NASA's Terra (launched 1999) and Aqua (launched 2002) satellites, continuing the Earth Radiation Budget Experiment mission. The SYN1deg product incorporates data from multiple instruments including CERES scanners and the Moderate-Resolution Imaging Spectroradiometer.
Use Cases
Model Earth's radiation budget based on calibrated Top of the Atmosphere (TOA) radiances.
Analyze cloud properties and their radiative effects based on coincident MODIS-derived data.
Study temporal trends in atmospheric energy fluxes based on hourly, 1-degree synoptic products.
Validate climate models using long-term, satellite-observed broadband channel measurements.
Strengths
Data collection is ongoing for the BDS product, providing a continuous time series.
Instruments follow the successful Earth Radiation Budget Experiment (ERBE) mission, suggesting a proven methodology.
SYN1deg product integrates data from multiple instruments (CERES, MODIS, geostationary satellites) for a more complete picture.
Includes raw Level-0 data and converted science data with additional parameters like satellite position and velocity.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and dataset size are unknown, which may limit suitability assessment.
The last update date is unknown; freshness unverified.
Provenance
Source
NASA CERES Project, part of the Earth Observing System (EOS).
Collection Method
Collected by CERES-FM2 and other scanner instruments on the Terra and Aqua satellite platforms.
Time Range
Covers periods from the Terra launch (December 18, 1999) and Aqua launch (May 4, 2002) onwards.
Freshness
Data collection for the SYN1deg product is complete, while collection for the BDS product is ongoing.
