CERES BDS Terra-FM2: Top-of-Atmosphere Calibrated Radiances

CER_BDS_Terra-FM2_Edition4 is a Clouds and the Earth's Radiant Energy System (CERES) data product from the FM2 instrument on the Terra satellite. It provides 24-hour Level-1B data samples, including geolocated and calibrated Top of the Atmosphere filtered radiances, raw instrument data, and converted satellite position data. The data is collected by NASA, with collection ongoing as of the last update in March 2026.

Use Cases

• Modeling Earth's radiation budget based on calibrated Top of the Atmosphere (TOA) radiances.
• Analyzing satellite instrument calibration and performance based on internal and solar calibration view data.
• Studying atmospheric radiation patterns using geolocated broadband channel measurements.
• Validating climate models with time-series data from a key Earth Observing System (EOS) component.

Strengths

• Data collection is ongoing, providing a continuous time series.
• Includes multiple data types: raw Level-0 data, converted science data, and additional parameters like satellite position and velocity.
• Part of a long-term mission lineage, following the Earth Radiation Budget Experiment (ERBE) and involving multiple satellite launches.

Limitations

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