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.

Note! There is some problems with the files below and links are borken. Please contact Fredrik Lindberg if you want to download something and he will help you. 

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.

Some of the tools is compiled using a 32-bit MCR but most of the tools make use of a 64-bit version. Make sure that you install the correct version on your PC. Information is given for each separate tool.


The Solar LongWave Environmental Irrandiance Geometry model (SOLWEIG) simulates spatial variations of mean radiant temperature and 3D fluxes of longwave and shortwave radiation.

Setupfile for both SOLWEIG 2015a and SOLWEIG1D.

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.
