Software download

The Göteborg Urban Climate Group has developed a number of different software which is freely available for download.

Most of the tools are available from of the Urban Multi-scale Environmental Predictor (UMEP), a comprehensive open source sensitive climate planning tool available as an plugin in QGIS.

Older tools 

All older software are written in MATLAB programming language and make use of a runtime engine called MCR (MATLAB Complier Runtime), which makes it possible to run MATLAB applications outside the MATLAB environment.

The MCR is deployed royaly-free and could be downloaded  from here.


The Solar LongWave Environmental Irrandiance Geometry model (SOLWEIG) simulates spatial variations of mean radiant temperature and 3D fluxes of longwave and shortwave radiation (Later versions are found in UMEP)

Setupfile for both SOLWEIG 2015a and SOLWEIG1D. 

DOWNLOAD (build 1: 2015-10-12, DEPRECATED, running with MCR 8.2 64-bit)

NB. One file is missing for SOLWEIG1D. Download this file (landcovercalles_2015a_1D.txt) and locate it in the same directory as the software itself.
