A3 Atmospheric Forecast Service


The A3 Atmospheric service currently allows the generation of meteorological forecasts, using the Weather Research and Forecasting (WRF) Model. Studies can be created by providing input files, including dateset and configuration files. These will then be queued to be computed by a WRF instance, and its outputs can then be download through a study’s detail page.


The service requires some input data to generate a forecast. These inputs consist on:

  • Meteorological data of the intended area of the simulation, in the GRIB1 or GRIB2 formats.

  • A Vtable file for the provided GRIB data file

  • 2 configuration files (namelist):
    • The first for the WRF Pre-Processing System;

    • The second for the WRF forecast execution itself.


The outputs are available in netCDF and JSON format, along with an initial visualisation of the results with plots saved to a PDF file.
