Název v původním jazyce

The use of radar and gauge measurements to estimate areal precipitation for several Czech river basins.

Popis výsledku v původním jazyce

Two methods estimating areal precipitation for selected river basins in the Czech Republic are compared. The methods use radar precipitation (the radar-derived precipitation estimate based on column maximum reflectivity) and data from 81 on-line rain gauges. Data from a dense network of climatological rain gauges are utilized for the verification. The first, pixel-related method merges radar precipitation with rain gauge data to obtain adjusted pixel values and the areal estimates are determined by adding the corresponding pixel values. The second method applies a linear regression model to describe the relationship between the areal precipitation and its estimates, which are determined from (i) non-adjusted radar precipitation and (ii) on-line rain gauge measurements interpolated into pixels. Both the methods decrease the average areal error in comparison with the reference method, which uses the on-line rain gauge data only.
