Exports profile data to file in NETCDF-CF format for Matroos |
Overview
Note |
---|
This export is available in DELFT-FEWS versions after 28-10-2009 (FEWS version 2009.02) |
Exports data to NetCDF files which comply to the CF 1.4 standard.
To indicate that data values are missing , NetCDF-CF exports use float value 9.96921e+036 by default. It is possible to change it by entering a different missing value (NaN or other) in the configuration files. Use option <exportMissingValue> in TimeSeriesExport module, and <missVal> in GeneralAdapter
More information about the cf standards can be found at: http://cf-pcmdi.llnl.gov/conformance/requirements-and-recommendations/1.4cfconventions.org/
There are six types of NetCDF-CF exports which can be defined:
...
The structure of the netCDF file which is created is shown below.
