Overview

Imports COSMO7 Corrected gridded forecast time series data as ASCII files that are delivered to FOEN in Switzerland by Meteo Swiss. The files contain COSMO7 corrected rainfall time series in mm. The files have an extension of *.dat, example of file name "gridpoints_dch.dat".

Configuration (Example)

A complete import module configuration consists of an ID Mapping file and an Import Module Instance file. Examples of the two are provided below.

The COSMO7 Corrected file has the following characteristics:

Missing value identifier is expected to be: -999
External Forecast time is included in the header line: MODEL RUNTIME: 2015101106
The data lines have the following format: COSMO|dmo|15101107|1H_PREC|1|4.8672|45.4421|0
- COSMO: not used
- Dmo: not used
- 15101107 is the date with format is “yyMMddHH”
- 1H_PREC is the parameter ID
- 1 is the cell number: not used
- 4.8672 is the x-coordinate of the cell: not used
- 45.4421 is the y-coordinate of the cell: not used
- 0 is the rainfall value for the grid cell

ModuleConfigFiles/

The following example of an Import Module Instance will import the gridded rainfall time series as equidistant 1 hour interval series for time zone GMT+0 hours.

IdMapFiles/

The ID mapping file will contain a mapping of the parameter and location in the data file with the internal parameter and location ID’s of the Delft-FEWS application.

<idMap xmlns="http://www.wldelft.nl/fews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.wldelft.nl/fews http://fews.wldelft.nl/schemas/version1.0/idMap.xsd" version="1.1">
	<parameter internal="P.fg" external="1H_PREC"/>
	<location internal="COSMO7_Corr" external="COSMO7_COR"/>
</idMap>
