7. DOE ARM CART

The Department of Energy (DOE) Atmospheric Radiation Measurement Program (ARM) operates a tremendous number and types of instruments. The Southern Great Plains is one of the Cloud and Radiation Testbeds (CART). Here a simplification of the extensive materials prepared by the ARM CART (http://www.arm.gov/docs/sites/sgp/sgp.html). The site layout is based upon a heavily instrumented central facility (CF) surrounded by 22 extended facilities (fewer instruments) (EF), 4 boundary facilities (BF), and 3 intermediate facilities (IF). Figure 1 includes the locations of all facilities.

Instrumentation at the CF is listed in Table 18. EF sites include the SIROS, SMOS, EBBR or ECOR, and SWATS. IF facilities include BBSS, MWR, and a 404 MHZ Wind Profilers. Each IF has a 915 MHz Wind Profiler.

The schedule for BBSS launches is as follows:

Routine Schedule CF-0600, 1200, 1500, 1800, 2100 UMT
            BF-1800 UMT (1200 local)
IOP Schedule CF-0300, 0600, 0900, 1200, 1500, 1800, 2100, 2400
            BF-0300, 0600, 0900, 1200, 1500, 1800, 2100, 2400

The Central facility includes two EF sites, one range and the other winter wheat. Therefore, many of the instruments are replicated for each cover type (radiometric observations, wind, temperature and humidity sounding systems, energy balance, surface meteorology, and soil moisture and temperature profile). There are currently 22 EF sites designed to primarily to monitor surface and moisture (energy balance, surface meteorology, and soil moisture and temperature profile).
