TITLE: Profiler/Sodar ARM Wind Profilers (915 MHz) [ARM] CONTACTS: Richard L. Coulter Environmental Research Division Argonne National Laboratory Argonne, IL 60439 Phone: 708-252-5833 FAX: 708-252-5498 E-mail: rl_coulter@anl.gov 1.0 DATA SET OVERVIEW This data set contains hourly vertical profiles horizontal wind speed and wind direction retrieved from the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) 915 MHz Radar Wind Profilers. The 915 MHz profilers were operated at the ARM SGP Central Facility and the three ARM SGP Intermediate Facilities. It also contains the 915 MHz profiler data from the Atmospheric Boundary Layer Experiement (ABLE) project in the Walnut River watershed in Kansas. This data set covers the period from 20 May to 31 July 2003. These data are in netCDF format. 2.0 INSTRUMENT DESCRIPTION 2.1 Instrumentation Complete information on the ARM 915 MHz profiler instrumentation is available from ARM at: http://www.arm.gov/docs/instruments/static/rwpr.html Complete information on the ABLE 915 MHz profiler and RASS instrumentation is available from ABLE at: http://gonzalo.er.anl.gov/ABLE/ 2.2 Station Locations Site Elevation (m) Lat.
