Hypothesis: Wind speed wiZZ be reduced, but air turbuZence wiZZ increase. Analysis of wind changes within the array will be very difficult because of the complexity of air movement around the collectors. It is possible, however, by utilizing a number of small anemometers. The overall array should reduce wind speed in interior areas, but turbulent mixing within the array may increase turbulent transfer, particularly under windy conditions. Periods of low wind may allow stable inversion layers to develop within the array and not in open desert areas. Hypothesis; Long-wave radiation emitted and Zost from the soiZ surface wiZZ be reduced. Interception by stowed heliostats or collectors will redirect emitted radiation back to the ground surface. Monitoring net all-wave radiation under collectors will determine if it is significant enough to provide warm microsites during periods of rapid cooling. Temperature profiles will give added information. Hypothesis: AZbedo from the coZZector area wiZZ decrease with time. The decrease in albedo which means more radiation held in the system will be due to increased density of plants causing more light absorption by the ground area in the array fields. This could increase the temperatures. Measurement of solar reflection from areas within the array will give information to test this hypothesis.
