HORAYZON

Package to efficiently compute terrain parameters (like horizon, sky view factor, topographic openness, slope angle/aspect) from high-resolution digital elevation model (DEM) data. The package also allows to compute shadow maps and correction factors for downwelling direct shortwave radiation for specific sun positions.

Terrain3D

Three-dimensional visualisation of terrain data from digital elevation models (DEMs) or climate model topography with PyVista. A set of Python example scripts illustrates how this data can be plotted for various domains and with auxiliary information.

Miscellaneous tools related to climate modelling with EXTPAR/COSMO

Precipitation_indices

Fast and accurate way to compute precipitation indices (temporal mean, maximum yearly/seasonal daily or hourly precipitation, wet day frequency and percentiles) from climate data with high spatiotemporal resolution.

grid_interpolation

Fortran code to interpolate between unstructured grid (triangle mesh) and regular grid.

Subgrid_radiation

Package to efficiently compute topographic parameters to consider the subgrid effects of complex terrain on surface radiation. Correction factors for direct downward shortwave radiation can be computed for a two-dimensional array of subsolar positions or individual positions.

Utilities

Various utilities for processing climate model data with Python. Grid and Remap functions are designed for model output on a regular horizontal grid (rotated latitude/longitude or map projection).
