The USGS Desert Winds Geologic/Meteorological Ground Stations
(GEOMET) provide a long-term data base for understanding the
range of environmental conditions that can be expected to occur
normally in
... arid and semiarid areas of the desert southwest,
baseline data to assess changes in the desert such as changes in
vegetation, migration of sand, and increased dust storms that
may occur due to climate change in desert regions, and data for
field-checking remotely sensed image data of various surfaces so
that regional models can be developed for monitoring the land
surface changes over time.
