Coordinated Energy and Water Cycle Observation Project

Coordinated Energy and Water Cycle Observation Project: overview of available data sets in the CERA Database.


CERA Gateway


M&D provide a special CEOP Gateway to the CERA database with about 5.63 TByte CEOP-related data.

Additional information

For a complete description of the CEOP-project, data-links and documents please consult the CEOP-homepage.

An overview of available data sets can be found at the offical CEOP data management page.

A documentation of model output is avaiblable from the CEOP Model Output Documentation page.


Here we start a new CEOP PHASE II page.

Structure of the model output

The structure of the model output can be found on the (pdf) CEOP Model Data Structure document.

For CEOP Phase II WDC-Climate proposes a more homogeneous (pdf) data structure for gridded data and MOLTS. The WMO-GRIB format is used for the gridded data. MOLTS can be stored in NetCDF-CF format as an example header of JMA data shows. Find a set of example NetCDF files (Also JMA) here: tar example. The tarball contains 4 NetCDF files for one day with the 12:00 file containing 72 forecast steps. The (pdf) Stationlist list of the station names with proposals for changes.
