Abstract. The Earth Cloud Aerosol and Radiation Explorer (EarthCARE) is a satellite mission implemented by the European Space Agency (ESA) in cooperation with the Japan Aerospace Exploration Agency (JAXA) to measure global profiles of aerosols, clouds and precipitation properties together with radiative fluxes and derived heating rates. The data will be used in particular to evaluate the representation of clouds, aerosols, precipitation and associated radiative fluxes in weather forecasting and climate models.

The science data acquired by the four satellite instruments are processed on ground. Calibrated instrument data – level 1 data products – and retrieved geophysical data products – level 2 data products – are produced in the ESA and JAXA ground segments. This paper provides an overview of the data processing chains of ESA and JAXA and explains the instrument level 1 data products and main aspects of the calibration algorithms. Furthermore, an overview of the level 2 data products, with references to the respective dedicated papers, is provided.

Short summary
The Earth Cloud Aerosol and Radiation Explorer (EarthCARE) is an ESA-JAXA satellite mission to be launched in 2024. We presented an overview of the EarthCARE processors development, with processors developed by teams in Europe, Japan and Canada. EarthCARE will allow scientists to evaluate the representation of cloud, aerosol, precipitation and radiative flux in weather forecast and climate models, with the objective to better understand cloud processes and improve weather and climate models.
