Abstract
Projects are described and results presented for three of the solar related activities presently underway: Solar Radiation Monitoring, Effects of Dust Accumulation on Collector Performance, and Salt Gradient Solar Pond Analytical and Experimental Studies. Measurements of total horizontal and direct radiation have been made continuously since May, 1979 and the data are presented in a user oriented format on an hourly basis. These results have been extended by calculation to allow presentation on an hourly basis of diffuse radiation and total radiation on a surface tilted to the local latitude angle. The system is presently being expanded to allow measurement of several additional radiation parameters of interest as well as six meteorological parameters. Some results are presented to show the effects of atmospheric dust on radiation attenuation, as well as the clearness index, anti K/sub T/. Results are also presented for a related study, the impact of surface dust accumulation on the performance of photovoltaic and thermal collectors. Continuous monitoring of the peak watt output of a small photovoltaic panel during a period which included severe dust storms showed a decrease in performance of sixty percent (60%) relative to the clean panel output.

Settling of dust on the surface of a solar pond does not, on the other hand, appear to be a problem. The salt gradient solar pond work is proceeding on two fronts: analytical and experimental. Preliminary results are presented for a varying property transient one dimensional computer model currently being used in design studies. Preliminary experimental results are also presented for temperature profiles measured in our small prototype pond.}
