Advanced techniques for precipitation estimates in alpine regions

Objective

The main objective is to combine precipitation measurements from rain gauge and weather radar detain complex terrain optimally, i.e. by reducing bias and variance of the resulting precipitation analysis. A new method which takes advantage of the error independence of gauge and radar measurements and uses block kriging and Bayesian combination conjunctively was developed at the host institution. The innovation compared to traditional methods lies in the reduction of both bias and variance of the resulting estimates. The new method will be adapted for use with data gathered by gauges and radar in Austria's complex topography. The results of the new method will be compared to the results of the conventional techniques. Additionally a new theoretical non-steady state test case will be developed to test the performance of methods such as empirical exponential weighting or co-kriging as well as the new method. training and impact for applicant:
