The towers are used for meteorological, radiological, and other measurements. Instrument systems installed on the towers are listed in section 7, Instrument Details, although only the Temperature/Relative Humidity/Vapor Pressure (T/RH/VP) measurements made on the SGP CF tower are described in detail. twr handbook is available at: http://www.arm.gov/publications/tech_reports/handbooks/twr_handbook.pdf 19970912 20031012 Completed None -95.59 -95.59 34.98 34.98 science keywords Atmospheric Radiation Measurement DOE ARM ARM ARM Observed Data Atmospheric Profiling Surface Meteorology Atmospheric State surface meteorology upper air state Humidity, relative, 25-m height, 1-min intervals Humidity, relative, 60-m height, 1-min intervals Temperature, air, 25-m height, 1-min intervals Temperature, air, 60-m height, 1-min intervals Pressure, vapor, 25-m height, 1-min intervals Pressure, vapor, 60-m height, 1-min intervals Atmospheric moisture Atmospheric temperature sgp30twr10xC1.a1 sgp30twr10xC1.b1 Instrument ARM Facility-specific multi-level Meteorological Instrumentation Place Keywords sgp.C1: Southern Great Plains ,Central Facility, Lamont, OK David Cook drcook@anl.gov Mailing and Physical Address Argonne IL 60439 N/A Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, USA ARM Archive User Services +1-865-241-4851 armarchive@ornl.gov url visualization http://www.archive.arm.gov/arm/Thumbnail2.jsp?siteCode=sgp&instClass=twr Public image thumbnail http://www.archive.arm.gov/quicklooks/2008/sgp/sgp30twr10xC1.b1/sgp30twr10xC1.b1.200811/.icons/sgp30twr10xC1.b1.20081130.000000.rh_25m.png Public Atmospheric Radiation Measurement (ARM) Program Data Sets. 1993-Ongoing.
