The EarthCARE mission is a satellite mission led by the European Space Agency (ESA) in collaboration with the Japan Aerospace Exploration Agency (JAXA) to measure vertical profiles of aerosols, clouds, and precipitation, along with radiative fluxes and heating rates. The mission aims to improve climate and weather models by evaluating the representation of clouds, aerosols, and radiative fluxes. The satellite carries four instruments: the Atmospheric LIDar (ATLID), the Cloud Profiling Radar (CPR), the Multi-Spectral Imager (MSI), and the Broadband Radiometer (BBR). Data from these instruments are processed on the ground to produce level 1 and level 2 data products. ESA and JAXA each have their own ground segments that process the data, with level 1 products being calibrated and geolocated, and level 2 products derived from these. The processing chains for ESA and JAXA are largely independent, with some shared products. The data products include calibration products for instrument settings and geophysical data such as cloud and aerosol parameters. The processing involves calibration, radiometric pre-processing, crosstalk management, and physical conversion. The data are provided in NetCDF-4/HDF5 format, with product naming conventions and formats defined for both ESA and JAXA. The mission will fly in a sun-synchronous orbit, with data products being disseminated to users by both agencies. The processing chain includes data calibration, retrieval algorithms, and simulation, with the aim of improving the accuracy of climate and weather models.The EarthCARE mission is a satellite mission led by the European Space Agency (ESA) in collaboration with the Japan Aerospace Exploration Agency (JAXA) to measure vertical profiles of aerosols, clouds, and precipitation, along with radiative fluxes and heating rates.
