These SMOS stations are located at many of the ARM SGP Extended Facilities in southern Kansas and northern Oklahoma. This data set covers the period from 13 May to 25 June 2002. The data are in netCDF format. 2.0 INSTRUMENT DESCRIPTION 2.1 Instrumentation Full information on the ARM SMOS instrumentation is available from ARM at: http://www.arm.gov/docs/instruments/static/smos.html 2.2 Station Locations Site Elevation (m) Lat.
