Fire weather calculator9/19/2023 ![]() ![]() Jointly produced with the European Centre for Medium Range Weather Forecasting. Global Early Warning System for Wildland Fires Global FWI forecasts are available from the GOFC-GOLD This system can be used for interactive mapping and plotting. After downloading, the data may be easily plotted and viewed using the Panoply Data Viewer.Īt Columbia University’s International Research Institute for Climate and Society. GFWED datasets are in netCDF (NC) format. The underlying weather data used for the calculations are also included, along with ancillary information such as snow cover used to start and stop the calculations. The example shown here is over the southeast US with Aqua/Terra MODIS active fires. The Fine Fuel Moisture Code is a good indicator of fire starts. ![]() A wget example to download a single file to the current directory is: GFWED data are distributed in NetCDF format from the NASA Center for Climate Simulation Dataportal at the URL:ĭownloads can be automated using the "wget" and "curl" tools. same retrieval but without TRMM instrumentsįinal research version with monthly rain-gauge correction.

Users may select up to six different elements at a time. A graph will appear illustrating at what times(s) the weather element criteria is met for the selected location. Users will select from a list of weather elements, input a criteria range for the selected element (i.e., temperature between 65 degrees F and 80 degrees F), and then select a location on the map. This is an experimental planning tool that provides specific weather forecast information based on the official National Weather Service forecast.
