Distributed input fluxes and basin properties estimation

This project area will estimate spatially distributed forcing fluxes and basin properties. The main flux is precipitation in its various forms. Particular emphasis will be placed on the estimation and evaluation of remotely sensed precipitation products, but simulated and merged precipitation estimates at the mesoscale will also be investigated. The second theme is the estimation of distributed basin properties to be used for the parameterization of land-surface hydrologic models at different spatial scales and resolutions. Relevant projects are listed below:

1. Estimating precipitation over the southwestern US at 6hr/12km resolution from remotely sensed data
2. Estimating precipitation over the southwestern US using regional scale mesoscale modeling
3. Comparison of estimation products from different mesoscale models
4. Coupled land-atmosphere simulation and prediction
5. Evaluating the quality of remotely sensed precipitation estimates for hydrologic modeling
6. A prior parameter estimation and scale issues for distributed hydrologic models
