This EarthCARE L1 collection is available only to the EarthCARE Commissioning Team and to Principal and Co-Investigators of accepted proposals to the ESA Announcement of Opportunity for the Validation of EarthCARE.

This EarthCARE collection is restrained, and contains the following data products:

• Level 1B: Fully Calibrated and Geolocated Instrument Science Measurements
  Level 1b data represents the fully processed, calibrated, and geolocated measurements from EarthCARE's instruments. Each measurement is aligned with the native instrument grid. For the Broadband Radiometer (BBR), measurements are also spatially integrated to various ground pixel sizes.

• Level 1C (MSI only): MSI Level 1b Data Interpolated to a Common Spatial Grid
  Specifically for the Multi-Spectral Imager (MSI), Level 1c data involves interpolating Level 1b measurements onto a standardised spatial grid that is consistent across all MSI bands. This grid closely matches the spacing used in MSI Level 1b data.

• Level 1D: Joint Standard Grid (JSG) for all instruments with ECMWF Meteorological Fields.
  Level 1d data provides a spatial grid to enable easy collocation and synergistic use of the data from all EarthCARE instruments, named the "joint standard grid." Additionally, this level incorporates ECMWF (European Centre for Medium-Range Weather Forecasts) meteorological fields limited to the EarthCARE swath, enabling comprehensive analysis and modelling of atmospheric conditions within the satellite's coverage area.
