Get Terrestrial Input Data

The latest version of the WPS processes fields for gravity wave drag schemes in both the ARW and the NMM. Regardless of whether a GWD scheme will be used, the static fields must be available in the directory where other static geographical fields are found. Accordingly, users who have downloaded the geographical data in the past must download the additional GWD_geog.tar.gz file and unpack it in their geog directory before using WPS Version 3.1. New users downloading the geographical data tar file since the Version 3.1 release do not need to download the GWD_geog.tar.gz file, since the GWD fields are now included in the standard geographical data tar file.
