CNRM

Format

The CNRM has built a schema on the NetCDF format to contain meteorological timeseries suitable for forcing snow models. The NetCDF (network Common Data Form) format has been created as a machine-independent format by the Unidata Program Center in Boulder, Colorado. It is an interface for array-oriented data access and a library that provides an implementation of the interface. In order to graphicaly explore the content and structure of NetCDF files, you can use the ncBrowse java software.

Keywords

This plugin uses the following keywords:

  • COORDSYS: coordinate system (see Coords); [Input] and [Output] sections
  • COORDPARAM: extra coordinates parameters (see Coords); [Input] and [Output] sections
  • METEOPATH: where to find the meteofiles as refered to here below; [Input] and [Output] sections
  • METEOFILE: the NetCDF file which shall be used for the meteo parameter input/output; [Input] and [Output] sections
  • UREF: height of wind measurements (in m, default 10m); [Output] section
  • ZREF: height of air temperature measurements (in m, default 2m); [Output] section
  • STRICTFORMAT: Whether the NetCDF file should be strictly compliant with the CNRM standard; Parameters not present in the specification will be omitted; [Input] and [Output] section

Example use

[Input]
METEO = CNRM
METEOFILE = ./input/meteo/forcing.nc

It is also recommended to use a dataGenerator on PSUM (for example, a constant generator set at 0) since Crocus does not accept nodata values (and re-accumulating the precipitation can still lead to nodata values).

Compilation

In order to compile this plugin, you need libnetcdf (for C). For Linux, please select both the libraries and their development files in your package manager.
