Equipment is being set up to measure various properties of desert clouds. The equipment includes a 3 cm. radar, a 0.86 cm vertically pointing radar, a GMD-1 rawinsonde, 12 weighing bucket rain gauges, cameras for stereophotography of clouds. The measurements will include cloud base, cloud height, growth rate of clouds, cloud base radius, rainfall rates, liquid water content, ambient atmosphere temperature, humidity, wind. Along with the observational set-up, a one-dimensional time-dependent plume model has been developed for predicting growth of desert clouds. The program is almost completely checked out. Information from the above-mentioned observational program will be used as input data and as verification data for the model. Author
