The Forecast Model Web Map Service (NFMW) is able to read the output of numerical models that simulate Earth science processes and to produce visualizations of the desired output field(s) showing the geographic area, time and elevation specified by the user. Users request visualizations according to the industry-standard Web Map Service (WMS). The model outputs are in formats such as HDF, NetCDF, GRIB or raw binary. The NFMW code reads data for the desired model run time, forecast time, and field(s), subsets the data to the region of interest, interpolates the data to the specified size, generates a visualization of the data using colors, contour lines or arrows, and sends the visualization to the client. The client is typically a normal web browser. The NFMW code is a combination or Perl and Interactive Data Language (IDL).|
The primary NFMW goal is to enable both expert scientists and members of the public to view the results of simulations through a normal web browser without needing to install or learn special software. A secondary goal was to demonstrate concretely the benefit of adopting open-standard interface specifications such as the OGC WMS.
