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.

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.

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).

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.
