Issues with SOLWEIG v2025a Wall Surface Temperature Output

[Naeim-Mj]

Hi, I hope you are doing well.
I have been using Outdoor Thermal Comfort: SOLWEIG v2025a (the version available in the QGIS Plugin repository) to analyze wall surface temperature. Despite several attempts, I am not getting any wall surface temperature output. The model runs to completion with no errors in the log, and all the usual rasters (Kdown/Kup, Ldown/Lup, Tmrt, Shadow) are generated, but no NetCDF file containing wall temperatures is created. I would be very grateful for any pointers or advice you could provide.

Hi Naeim,

Try this version (install with zip in QGIS) and hopefully it works. Otherwise, reply here. :)

UMEP-processing-main-netcdf.zip

Cheers,

Hi,

I've been trying to run the new version, but I keep getting the same error message attached. This error did not occur before, and the model used to run without any issues; however, it did not provide the wall surface temperature.
I've checked the input data and tested different settings, but the error still persists. Just to mention, I'm using the test data you shared on GitHub.
I would appreciate it if someone could take a look and see what might be causing this issue.

Thanks,
Naeim
