TITLE: Profiler/Sodar ARM Radio Acoustic Sounding System (RASS) (915MHz) [ARM] CONTACTS: Richard L. Coulter Environmental Research Division Argonne National Laboratory Argonne, IL 60439 Phone: 708-252-5833 FAX: 708-252-5498 E-mail: email@example.com 1.0 DATA SET OVERVIEW This data set contains hourly vertical profiles of virtual temperature and vertical wind velocity retrieved from the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Radio Acoustic Sounding System collocated with the 915 MHz Radar Wind Profilers 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 and RASS 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.
