Weather Forecast

The Weather Forecast application can be used to show worldwide and/or local weather forecast data when connected to HydroNET. It allows easy online access to the weather forecast incorporated into an interactive geographical map.

Precipitation forecast for any location

The precipitation forecast will be provided for any location in the country. Just click on the map, and the forecast will be presented in a graph. Use the interactive dashboard to know what is coming. Select the locations and the dashboard gives an overview of the most recent weather information on every rain storm.


  • Access to weather forecasts per grid/average per polygon on an interactive map
  • See what is coming via the forecast animation
  • Interactive dashboard: access to the latest forecasts for any location
  • Export time series to run your models
  • Export time series chart to images (PNG, SVG, JPEG) or an Excel file (CSV)

Weather Stations

The Weather Stations application allows direct access to current and historical time series from automatic weather stations. You can access this data from behind your desk. The application automatically collects large amounts of gauge data and makes it accessible via internet. Just select the period, the stations and variables you are interested in. Press the button and you will automatically receive the requested information as a graph, picture or in an Excel file.

Get insight into the spatial variation of rainfall events

With the interactive dashboard, the latest information (last day, last week, last month, last year) from the selected gauges will be presented. It is also possible to present more gauges in one graph to get insight into the spatial variation.


  • Selection of period
  • Selection of station(s)
  • Selection of variables
  • Interactive dashboard: compare rain gauges and presentation of real-time data.
  • Download time series for any gauge
  • Export time series charts to images (PNG, SVG, JPEG) or an Excel file (CSV).

The HydroNET RainMap application allows online access to historical and current rainfall information for any location, also between the gauges. The application automatically:

  • collects and stores large amount of rainfall data from radars, satellites, numerical weather prediction models and automatic weather stations in real-time
  • combines the different rainfall sources into a “best available” gridded rainfall product
  • makes historical and actual precipitation data easily accessible via the web browser (no software installation needed).

Rainfall information from radars, satellites, models and gauges

Select a period and the RainMap provides the best available precipitation information per pixel or per area. Via an interactive geographical map the requested precipitation sum (map) and precipitation intensity per time step (graph) can be presented per pixel or area.


  • Upload tool which allows you to upload shapefiles which will become available in the RainMap application
  • Download tool which allows you to download long precipitation time series per pixel or per area in different well-known formats (e.g. CSV).
  • Personalised Dashboard: determine what information you want to see in order to make reliable decisions.
