Downloading the Data

All (current and past) versions of ESA CCI SM data can be downloaded for free and without registration from the CEDA Archive under "data/daily_files".

Using the Data

For information on how to use the product, please read the Product User Guide (PUG). This is also available in the docs folder of the FTP site (from which the data can be downloaded).

The downloadable data is provided in 2D (longitude, latitude) image files representing one day of the record. A package is available in python for reading the data as daily images and converting these images to time series and reading them.

Any software that can handle CF conform data should be able to import the raw .nc files (e.g. CDO, NCO, QGIS, ArCGIS, Matlab, R, ...). You can also use the GUI software Panoply to view each file.
