* A data factory for getting radar data from the metadata database. There are

*
* Radar does not return subgrids for request envelopes like other gridded
* types. Instead data for only icaos within the request envelope are returned
* and all data for the product is used. This is done because subgridding radial
* products is complex and this is not often what a caller actually wants.
