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.
Almost all CM SAF Climate Data Records (CDRs) and all Interim Climate Data records (ICDRs) and Fundamental Climate Data Records (FCDRs) are provided in NetCDF. CM SAF offers a basic set of transformations on its products due to the integration of some cdo functionalities into our Web User Interface (for more information on cdo, please follow the tools link below). The CM SAF WUI offers the opportunity to interpolate onto a regular latitude/longitude grid and/or to select a sub-domain.
Below you find some product example files to get a first impression of what you will receive in case of ordering:
- Fractional Cloud Cover, monthly mean - CFCmm201003010000320070023201MA.nc (compressed)
- Vertical integrated Water Vapour, daily mean - HTWdm200806110000300110017301GL.hdf
- Surface Albedo, weekly mean - SALwm200806020000310070010901CA.hdf
If you are interested in other grid types, CM SAF recommends to install cdo and to manipulate the products yourself. CM SAF also provides an R TOOLBOX, as an easy-to-use tool to prepare, analyse and visualise CM SAF NetCDF data. For installation instructions and some examples for the use with CM SAF data please follow the tools link below.
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. Links to product-specific auxiliary data for the CM SAF CDRs are provided on the respective DOI landing pages.
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: 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.
