Python warning when running the Footprint model (Source Area Model (Point))

[lkarch]

Hello,

I have an issue when running the Footprint model. When setting the values directly inside the dialog box, the algorithm does not encounter any issues and works perfectly fine. Now I would like to use an input file with associated time stamps, but after a while, I get the following warning:

2024-04-17T11:50:54 WARNING Traceback (most recent call last): File "C:\Users/user/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\FootprintModel\footprint_model.py", line 578, in start_process fp.footprintiterKLJ(iterations=it,z_0_input=z_0_input,z_d_input=z_d_input,z_ag=z_m_input,sigv=sigv, File "C:\Users/user/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\FootprintModel\KingsFootprint_UMEP.py", line 293, in footprintiterKLJ FFP = FFP_climatology(zm=z_m, z0=z_0, umean=None, h=hbl, ol=L, sigmav=sig_v, ustar=u_star, File "C:\Users/user/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\FootprintModel\KingsFootprint_UMEP.py", line 613, in FFP_climatology sigystar_dummy[px] = (ac np.sqrt(bc np.abs(xstar_ci_dummy[px])**2 / (1 + UnboundLocalError: local variable 'xstar_ci_dummy' referenced before assignment

And the run never ends. I have attached the input file I use. input_parameters.txt

I am currently using QGIS 3.28.9 on Windows 10 with UMEP version 4.0.4.

What raster data (london test data?) are you using and what footprint model (Kjiun?) was selected?

[lkarch]

I was using my own data and Kjlun method. I just tried with the London test data and it seems to work fine. There must be a problem with my DSM and DEM files (could their extent be too small?). I'll try to fix it.

Did you solve this? Can I close?

I am closing this. Start a new issue if this error still exists or start a Discussion.
