Test data:
CMEM Input/Output are coded in a modular way, so that the user can choose either ASCII, GRIB or NETCDF I/O format. For any of these I/O type, CMEM is flexible with automatic detection of the Input files sizes. See the description the description of CMEM I/O and Modelling Platform decriptioninput/output .
A test data set for CMEM v.6.0 is provided, including input/Output in the three formats (grib, acsii, netcdf). It is compatible since cmem 1.3. Output files are obtained with CMEM v4.0.
Note that for grib input/output you can use either GRIB API encoding ('gribapi' option, which is the default in cmem v2.1) or GRIBEX encoding ('gribex' option which was the default option until cmem_v1.3, named 'grib' at this stage).
