EarthCARE Satellite Calibrated Instrument Measurements and Meteorological Fields

EarthCARE L1 Products contain fully calibrated and geolocated science measurements from four satellite instruments. The collection includes Level 1b data for each instrument, a common grid for the Multi-Spectral Imager, and a joint standard grid collocating all instruments with ECMWF meteorological fields. This data is produced by the European Space Agency (ESA) with contributions from JAXA and ECMWF.

Use Cases

• Analyze calibrated radiances from the Broadband Radiometer (BBR) spatially integrated to various groundpixel sizes for top-of-atmosphere energy budget studies.
• Interpolate Multi-Spectral Imager (MSI) Level 1b measurements onto the standardized Level 1c grid for consistent multi-band cloud and aerosol property analysis.
• Collocate Cloud Profiling Radar (CPR) and other instrument data on the Level 1d Joint Standard Grid (JSG) for synergistic cloud vertical structure retrievals.
• Incorporate ECMWF meteorological analysis and forecast fields (AUX_MET_1D) limited to the satellite swath to contextualize atmospheric state within instrument measurements.

Strengths

• Provides fully calibrated and geolocated measurements from four distinct Earth observation instruments.
• Includes a dedicated Joint Standard Grid (JSG) product enabling collocation and synergistic use of data from all instruments.
• Integrates authoritative ECMWF meteorological fields directly onto the satellite observation swath for analysis.

Limitations

• Specific row counts, file sizes, and temporal coverage of the data records are not provided.
• The description does not specify the spatial resolution or exact geographic coverage of the instrument swaths.
• Data accessibility and license terms for the combined ESA, JAXA, and ECMWF products are unclear.
