Overview

The WIWB Import connects to the Hydronet WIWB API and has support for downloading observations and forecasts for both scalar and grid data. WIWB has a concept of DataSources which have to be configured as a property of the import. Using the meta data api of  the WIWB API the type of data is determined and processed accordingly.

Import Configuration

To configure the WIWB import the dataSource property has to be specified.

Valid values for dataSource are provided by the meta data api, but at the time of writing the following dataSources are available:

  • Knmi.Radar.Uncorrected
  • Knmi.Radar.CorrectedC2
  • Knmi.Radar.CorrectedB
  • Knmi.Radar.CorrectedD2
  • Knmi.Hirlam
  • Knmi.Harmonie
  • Knmi.Evaporation
  • Knmi.IrisUnvalidated
  • Knmi.IrisValidated
  • Knmi.RegionalEps
  • Knmi.Synops
  • Knmi.WaterSetupEps
  • Knmi.Warnings
  • Knmi.AwsTenMinutes
  • Meteobase.Evaporation.Makkink
  • Meteobase.Evaporation.PennmanMonteith
  • Meteobase.Precipitation
  • Knmi.WaquaTs
  • Knmi.Naval.Warnings
  • Knmi.Naval.Forecasts
  • Knmi.FromMeteobase.Synops
  • Knmi.FromMeteobase.Evaporation

Missing values.

If the WIWB specifies the missing value for a datasource, this will be used by FEWS. The missing value can also be specified in the import configuration as well. The default value for missing value is -9999 for the WIWB API.

Grid definitions

The WIWB API can provide the grid definitions of the models. The WIWB Import will log the Grid Definition if debug is enabled during the import.

Examples

This example is configured to import scalar observations from the Knmi.AwsTenMinutes dataSource:
