Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
Liu, Hongli; Thiboult, Antoine; Tolson, Bryan A.; Anctil, François; Mai, Juliane (Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Event-based model calibration approaches for selecting representative distributed parameters in semi-urban watersheds
Awol, Frezer Seid; Coulibaly, Paulin; Tolson, Bryan A. (Elsevier, 2018-08-01)The objective of this study is to propose an event-based calibration approach for selecting representative semi-distributed hydrologic model parameters and to enhance peak flow prediction at multiple sites of a semi-urban ... -
The pie sharing problem: Unbiased sampling of N+1 summative weights
Mai, Juliane; Craig, James R.; Tolson, Bryan A. (Elsevier, 2022-02)A simple algorithm is provided for randomly sampling a set of N+1 weights such that their sum is constrained to be equal to one, analogous to randomly subdividing a pie into N+1 slices where the probability distribution ...
