Overview
Imports high resolution precipitation analysis and forecast data from Radolan/Radvor-OP files from Deutscher Wetterdienst (DWD).
The data is GRID typed data.
File structure
A range of data products from DWD radar observations and/or derived from radar observations are delivered in binary files. The heading in the file is ASCII text (hence human readable) and is used to determine for which parameter the file contains data.
The remainder of the file contains the data in binary format.
This import can read data for the following data products; the product identifier is used as parameter ID during import:
Product identifier | Grid dimensions |
|---|---|
TZ | 1500 x 1400 |
TH | 1500 x 1400 |
RX | 900 x 900 |
PC | 230 x 230 |
PF | 200 x 200 |
| PG | 460 x 460 |
PN | 360 x 360 |
PI | 360 x 360 |
DX | 360 x 128 |
DQ | 360 x 128 |
DXQ | 360 x 128 |
Configuration
To import configure a module like this:
<?xml version="1.0" encoding="UTF-8"?>
<timeSeriesImportRun 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/timeSeriesImportRun.xsd">

idMapping
The parser assigns the product ID found in the header to ParameterID.
LocationID is taken from the header in case of PF, DX, DQ, DXQ.
In other cases LocationID is not set.
To map these to current FEWS location and parameter an idMapping can be configured.
For example:
<?xml version="1.0" encoding="UTF-8"?> <idMap version="1.1" 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"> <parameter external="RX" internal="P.radar"/> <location external="10410" internal="Loc10410"/> </idMap>
