Instrument : Facility-specific multi-level Meteorological Instrumentation (TWR)
Instrument Categories
Surface Meteorology
General Overview
Three tall towers are installed at Atmospheric Radiation Measurement Climate Research Facility sites: a 60-m triangular tower at the Southern Great Plains (SGP) Central Facility (CF), a 21 m walkup scaffolding tower at the SGP Okmulgee forest site (E21), and a 40-m triangular tower at the North Slope of Alaska (NSA) at Barrow. 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. Information on measurements made by the other instrument systems on the towers can be found at individual instrument systems web pages.
