Downscaling Tool

• The ClimaProof Downscaling Tool assists with downscaling data for applications that need a higher resolution than the 0.1° provided by default.

For the interpolation from 0.1° to 0.01° either a bilinear interpolation or the patch algorithm, developed by the Earth System Modelling Framework (ESMF), can be used. To take into account the more detailed topography at 0.01° a height correction is applied (to all parameters except precipitation).

Features of the Downscaling Tool are:

• selection of the area of interest by latitude and longitude,

• selection of the data that should be downscaled (gridded observations or model data),

• saving downscaled data as a CF-conform netCDF file.

The downscaling tool is provided free of charge and can be downloaded from the BOKU-Met GitHub repository https://github.com/boku-met/climaproof-tools.

A step-by-step instruction can be found in the User Guide under Training Materials.
