• We propose to study the accuracy of precipitation products, both instantaneous and accumulated, constructed by moving precipitating areas using model winds. In brief, the process we propose is as follows:
• We will use 88D radar data (Stage II and/or Stage IV) to simulate the satellite-observed rain rates. This may include a simulation of satellite footprints. It certainly will include a simulation of the satellite swath and orbital observation frequency.
• We will use GFS winds to move the rain rates to a later time, and we will accumulate the precipitation.
• We will compare the moved and accumulated precipitation with later Stage II /IV data to see how well the movement of the precipitation compares to actual.
• Real precipitating regions change with time. We will also look at whether model trends can be used to indicate an increase/decrease in precipitation during the gaps.
• We expect to examine one summer’s precipitation data over the CONUS. This should give us a good idea of how well precipitation estimates can be made with infrequent satellite observations.
