Multiscale Parameter Regionalization
MPR uses transfer functions to translate high-resolution predictors to model parameters throughout a diverse range of resolutions from few to hundreds of kilometres. It consists of two steps (Fig.~1):
- the use of transfer functions to translate high-resolution predictors into high-resolution model parameters
- upscaling of high-resolution model parameters to the scale at which the model is applied
The MPR stand-alone software package
MPR has been developed for the mesoscale Hydrologic Model (mHM, Samaniego et al. 2010, Kumar et al. 2013) and has been expanded to other models like PCR-GLOBWB (Samaniego et al., 2017). It is now available as a modular, stand-alone software. It allows to make use of high-resolution data sets for parameter estimation. Estimated parameter fields are written in a netCDF file that can be used in any model.
MPR is controlled with a single configuration file. All the predictors (e.g., sand and clay content), the transfer function, and upscaling operator can be freely chosen as a text string in this file. MPR is written in Fortran and support for all operating systems (Windows, Gnu/Linux, Mac OS) is given.
