Dataset Tab

The Datasets tab is subdivided into three subtabs: Geo, Met, and Process

Geo

Select and download pre-converted Geogrid binary datasets to be used with Geogrid using the Download Selected Datasets. The Geogrid binary datasets are downloaded and saved in the GIS4WRF working directory under GIS4WRF_WORKING_DIRECTORY/datasets/geog.

Geographical Datasets Tab

Met

Download NCAR's datasets supported by WPS from NCAR's Research Data Archive (RDA). A valid RDA account is required to use this utility and the username and password must be set in QGIS > Settings > Options.. > GIS4WRF section -- for more info see here. Currently we support five common datasets as shown in the table below.

Dataset ID Description
ds083.0 NCEP FNL Operational Model Global Tropospheric Analyses, April 1997 through June 2007
ds083.2 NCEP FNL Operational Model Global Tropospheric Analyses, continuing from July 1999
ds083.3 NCEP GDAS/FNL 0.25 Degree Global Tropospheric Analyses and Forecast Grids
ds084.1 NCEP GFS 0.25 Degree Global Forecast Grids Historical Archive
ds090.0 NCEP/NCAR Global Reanalysis Products, 1948-continuing

When the dataset name is selected, the available product names for the specific dataset become available. Start and end date and time are automatically restricted to the available periods for the specific dataset. Requests can be subsetted by clicking on the subset button. When the Download button is clicked, the request will be automatically sent to RDA and automatically downloaded when the download link becomes available (Note that if the request is large it may take a while before the data is downloaded). The data are downloaded and saved in the GIS4WRF working directory under GIS4WRF_WORKING_DIRECTORY/datasets/met.

Meterological Datasets Tab

Process

Convert QGIS raster layers to WPS binary format data and open pre-existing WPS binary format datasets. The tool supports the conversion of of categorical and continuous data.
