The A3 Atmospheric service allows the generation of meteorological forecasts. Once a study is created, it is queued to be computed by the Weather Research and Forecasting (WRF) Model. The status of a user's studies can be followed in the List page, where it is possible to access each study in more detail. When a study is completed, the outputs will be available in that study's details page. The outputs are available in netCDF and JSON format, along with an initial visualisation of the results with plots saved to a PDF file.
