CM SAF - Data access

The following pages provide the opportunity to search and order CM SAF products and to get detailed information about these products. The data provision is free of charge but a user registration is mandatory to get access.

To all Newcomers: Please take notice of the product sample files, the auxiliary data as well as the add on products and provided tools below.

Product examples

Almost all CM SAF Thematic Climate Data Records (TCDRs) and all Fundamental Climate Data Records (FCDRs) are provided in NetCDF. However, most of the CM SAF operational Environmental Data records (EDRs) are provided as HDF5. As many users are interested to receive the data records in different formats or projections, CM SAF offers a basic set of conversions/transformations on its products due to integrating some cdo functionalities into our Web User Interface (for more information on cdo, please follow the tools link below). Besides the pure conversion of CM SAF HDF5-files into NetCDF format, we offer the opportunity to interpolate onto a regular latitude/longitude grid and/or to select a sub-domain.

Below you may find some product example files to get a first impression of what you will receive in case of ordering:

If your preferred product format is not HDF5 / NetCDF or you are interested in other grid types, CM SAF recommends to install cdo and to manipulate the products for yourself. For cdo installation instructions and some examples for the use with CM SAF data please follow the tools link below.

Auxiliary data

CM SAF products are available covering different areas in different spatial resolution. Below you find a link to download files providing information on latitude/longitude, elevation, and fraction of land and water as well as a land/sea mask.

Add on products

Add-on products are provided to the user in addition to the official CM SAF products. They cover different application areas and facilitate the analysis of the CM SAF products and the climate system.


CM SAF supports the use of different tools to work with CM SAF grid-based product files: The GUI is an IDL-based tool to display CM SAF cloud and radiation products. To analyse and manipulate the products CDOs can be used, whereas the software tool R can be used to visualise and analyse CM SAF data records.
