Abstract
The application of radar rainfall measurements to hydrologic practices involves many difficulties in identifying radar constants B and β, calibrating radar information via use of ground measurements and so forth. The currently used method compares radar areal rainfall directly with ground point rainfall in spite of the difference of space scale. It is of practical importance to develop a new method which can take into account the space sacle difference for comparing radar measurements with spatial ground information precisely.
The present study converts ground point rainfall to average areal rainfall, using the Kriging method which enables one to estimate the average rainfall over a given catchment area, quantify the accuracy of areal estimates, provide data input for automatic contouring and design the raingauge networks.
