HIRLAM NWP data
DMI is extracting ZTD's, pressure and 2mT information from the operational
NWP model HIRLAM for the locations of the GPS sites delivering data for
TOUGH. The data are meant for validation, for studies of error statistics,
and for conversion of ZTD's to ZWD or IWV at institutes where that is needed,
but where superior
information (from observations or a local NWP model)
enabling the conversion is not available.
The extraction of data and calculation of delays are described in
detail in the
