Summary

Planning for the initial complement of instrumentation at the first Clouds and Radiation Testbed (CART) site has concentrated on obtaining a sufficient level of instrumentation at the central facility for studies of radiative transfer processes in a narrow column above the site. The auxiliary facilities, whose sole purpose is cloud mapping above the central facility, will not be activated as such until provisions are made for all-sky imaging systems. In the meantime, the auxiliary facilities wig be instrumented as extended facilities if the locations are suitable, which would be the case if they serve the primary purpose of the extended facilities of obtaining representative observations of surface energy exchanges, state variables, precipitation, soil and vegetative conditions, and other factors that must be considered in terms of boundary conditions by single-column and related models. The National Oceanic and Atmospheric Administration (NOAA) radar wind profiler network is being considered to provide observations of vertical profiles at the boundaries of the CART site. If possible, these locations will be used for boundary facilities. Efforts are proceeding to gain access to the wind profiler network data and to determine if a sufficient number of the profilers can be equipped as Radio Acoustic Sounding Systems (RASS). Profiles of temperature as well as winds are needed at the boundary facilities for studies with single-column models and four-dimensional data assimilation models. Balloon-home sounding systems will be used there initially for both temperature and moisture profiles. Infrared spectrometers will eventually be used to infer moisture profiles at these boundary facilities.
