Description of Instrumentation Sites

Data-collection platforms equipped with instrumentation that continuously measures and logs micrometeorological and soil-moisture parameters were installed at two sites. These data were used to compute ET and also can be used to develop infiltration profiles.

One platform, referred to in this report as the tree site, is in a sparse to moderately dense pinyon and juniper forest. The site is characterized by a vegetation cover of about 20 to 30 percent (fig. 3A) and is co-located with a meteorological tower operated by the National Oceanic and Atmospheric Administration (NOAA) Air Resources Laboratory. The site is at a latitude of 37º11'28.5"N and a longitude of 116º12'59.4"W, and at an altitude of 2,283 m above sea level.

A second platform, referred to in this report as the brush site, is in a sparsely vegetated community of perennial grasses and high-desert scrub brush (fig. 3B). This site is dominated by rabbitbrush and characterized by a vegetation cover of about 10 to 20 percent. It lies in an open field within a small bowl-shaped valley at a latitude of 37º10'48.4"N, and a longitude of 116º12'25.27"W, and at an altitude of 2,290 m above sea level.
