Spatial and temporal sampling errors in rainfall fields reconstruction through meteorological radar data

The accuracy in the reconstruction of space-time rainfall fields through radar rainfall estimates depends both on the accuracy of the estimate in the radar sample volume, and on the data updating capability of the radar system. The last aspect becomes of capital importance when the monitored phenomenon exhibits a high variability both in space and in time. This paper analyzes the problem of the optimal choice, depending on monitored event, of parameters of the radar acquisition, to minimize the error in reconstructing a rainfall field through the radar observation
