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: dataSource

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.

This example is configured to import 2D Hourly grids for the last 24 hours:
