EO Sign In Authentication (Open): This collection is openly accessible but requires users to log in with an EO Sign In account (a system used across ESA Earth Observation services) before any downloads can proceed.

Access Steps:

1. Create or log in to EO Sign In account
2. Go to the ESA MAAP Explorer
3. Browse or search for the product using the interactive map. 
4. Download product.

EarthCARE data can also be discovered and downloaded through the use of APIs (e.g. STAC) through the ESA MAAP Catalogue, using access tokens. Go to the MAAP Catalogue guide to learn more about how to use APIs and see the MAAP Explorer user guide for instructions on exploring, visualising, and accessing data interactively.

This EarthCARE collection contains the following data products:

• Level 1B (L1B): Fully Calibrated and Geolocated Instrument Science Measurements
  L1B 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 (L1C) Multi-Spectral Imager only (MSI): MSI Level 1B (MSI L1B) Data Interpolated to a Common Spatial Grid
  Specifically for the Multi-Spectral Imager (MSI), L1C data involves interpolating L1B measurements onto a standardised spatial grid that is consistent across all MSI bands. This grid closely matches the spacing used in MSI L1B data.  

• Level 1D (L1D): Joint Standard Grid (JSG) for all instruments with ECMWF Meteorological Fields.
  L1D data provides a spatial grid to enable easy collocation and synergistic use of the data from all EarthCARE instruments, named the "joint standard grid." 

• CPR Level 1B (L1B): C-NOM products
  Generated and provided by JAXA. This product is used as input, in combination with the X-MET aux file, for different processors in the EarthCARE production chain.
