CAIPEEX Radar Observations
Radar observations were made by a EEC WSR–74C C–Band (5 cm wavelength) weather radar installed in Solapur. The original system has been upgraded to include Advanced Radar Corporation (ARC) HiQ digital receiver. Radar data are being displayed and archived using the NCAR designed and supported Thunderstorm Identification Tracking Analysis and Nowcasting (TITAN) software.

The information provided by radar observations is used to develop the experimental design. Based on this information, statistical models are used to estimate parameters of the experimental design. For example, if a randomized seeding experiment is being implemented, this information is used to determine the number cases that are needed based on the storm attributes to detect a statistically significant difference between seeded and non–seeded clouds for various levels of rainfall enhancements (e.g., 5, 10, 20% effect in rainfall accumulation). The number of cases along with the storm frequency would then help determine the length of the experimental program that should be conducted.
