“…Description of the instrument is given in Table 2. The IRE scientists have developed algorithms for assessing several types of land surface variables, including surface and profile soil moisture, soil salinity, and vegetation biomass (Mkrtchjan et al 1988). Also on board the aircraft was a color video camera for recording flight-marker locations.…”

Arid and semiarid rangelands comprise a significant portion of the earth's land surface. Yet little is known about the effects of temporal and spatial changes in surface soil moisture on the hydrologic cycle, energy balance, and the feedbacks to the atmosphere via thermal forcing over such environments. Understanding this interrelationship is crucial for evaluating the role of the hydrologic cycle in surface-atmosphere interactions. This study focuses on the utility of remote sensing to provide measurements of surface soil moisture, surface albedo, vegetation biomass, and temperature at different spatial and temporal scales. Remote-sensing measurements may provide the only practical means of estimating some of the more important factors controlling land surface processes over large areas. Consequently, the use of remotely sensed information in biophysical and geophysical models greatly enhances their ability to compute fluxes at catchment and regional scales on a routine basis. However, model calculations for different climates and ecosystems need verification. This requires that the remotely sensed data and model computations be evaluated with ground-truth data collected at the same areal scales. The present study (MONSOON 90) attempts to address this issue for semiarid rangelands. The experimental plan included remotely sensed data in the visible, near-infrared, thermal, and microwave wavelengths from ground and aircraft platforms and, when available, from satellites. Collected concurrently were ground measurements of soil moisture and temperature, energy and water fluxes, and profile data in the atmospheric boundary layer in a hydrologically instrumented semiarid rangeland watershed. Field experiments were conducted in 1990 during the dry and wet or "monsoon season" for the southwestern United States. A detailed description of the field campaigns, including measurements and some preliminary results are given.

“…Based upon multifrequency information, the IRE has developed procedures for estimating several types of land surface variables. These include; sulface soil moisture, profile soil moisture, depth to shallow groundwater table, soil salinity, and vegetation biomass (Chuklantsev and Shutko 1988, Mkrtchjan et a[. 1988, Reutov and Shutko 1990, Shutko 1986).…”
