Hello everyone, I am new to this area, but i am wondering if someone else has as well encountered the error message by plotting the scan_strategy-function? Plotting the scan strategy with: ax = wradlib.vis.plot_scan_strategy(ranges, elevs, sitecoords, beamwidth=vol.how.beamwH) works fine. But if I…

This should be fixed in wradlib 2.0.2 But you’ll need a EARTHDATA account correctly setup: See Plotting Radar Scan Strategy — wradlib . HTH, Kai

Hi Kai, thanks a lot. I updated wradlib to 2.0.2, but I still get some errors. If I use: ax = wradlib.vis.plot_scan_strategy(ranges, elevs, sitecoords, cg=True, …

Hi Julian, not sure, it would be great, if you can make a little MCVE from your example. So at least give the input data you have used. This will help to reproduce issue and find a way around it. This might be a bug using units='km'. Does it work if you omit that kwarg? Another possible cause migh…

That’s what I have so far: import xarray as xr import datatree import wradlib import os os.environ["WRADLIB_EARTHDATA_BEARER_TOKEN"] = "my_bearer_token" os.environ["WRADLIB_DATA"] = "/path/to/my/folder" fname = "/home/ba9817/phd/finland/radar/hdf5/20220126/202201260930_fiika_PVOL.h5" # can be dow…

@lou Code looks good. The RuntimeError: No usable source images. might it have to do with the coverage of the SRTM data? IIRC it’s only covered to 60deg north. Do you have a local DEM covering whole of Finland? We might just skip the automated SRTM download and prepare the terrain ourselves from lo…

[image] kmuehlbauer: The altitude-problem is probably a bug in the curvelinear grid code, as the issue also shows up in the docs. Good catch! Would you mind opening an issue on the wradlib github issue tracker Issues · wradlib/wradlib · GitHub ? Confirmed, it’s a bug, we get this offset of 100…

Indeed, I forgot about that the SRTM data covers only the area up to 60deg north. I don’t have a local DEM covering Finland - I’ll have a look if I can find one and implement it. Good to know about maxalt! I think I don’t feel capable of fixing this in the code as I don’t know what the right way w…

@lou The altitude issue is fixed in wradlib 2.0.3, already available in PyPI. Next day in conda-forge.

You might wanna take a look at this topography: https://portal.opentopography.org/datasets?minX=7.2674560546874565&minY=63.01448255321023&maxX=41.27563476562497&maxY=71.86221497468833

I have as well found: Karttapaikka - Maanmittauslaitos I downloaded some Geo-Tiff files that I need. But I could not figure out how I should now process these data in order to implement it into the scan_strategy-function? Would you mind to help me out? And, @kmuehlbauer , is there a way to add a st…
