WRF output seems to be in a different location #212

Closed sirius25y closed 2 years ago

sirius25y commented 2 years ago

After successfully running GIS4WRF, I couldn't see the output when I visualize output.

I tried to open the output in another QGIS window and it appears to be in another location. However, I think this is just because of the output file having no coordinate system? I looked at the tutorial output and it is in the same location as this output, but I can see the tutorial output when i click "visualize output". How do I correct this?

My domain is the following: dx = 9000.0 dy = 9000.0 ref_lon = 153.022267 ref_lat = -27.46915099999936

I tried this again with a different project. This time using Lambert (the previous one was done using Mercator) and I don't have the same issue.

If I remember correctly, then QGIS has a weird bug where it shows things in the wrong locations when you're zoomed out a lot, and that may depend on the projection used. Did you try zooming in with your initial attempt?

sirius25y commented 2 years ago

Yes I did. I just had a few more tries and it seems to only happen with Mercator.

What's the extent of the domain? Would it make it roll over west?

sirius25y commented 2 years ago

No, it’s just 9km x 9km. I practically did everything from the tutorial except the domain. The centre is located in Brisbane, Australia.

OK yes that shouldn't make it roll over. There are a couple of test for Mercator but I never actually use it so you may have found a bug. Will need to investigate this further but cannot estimate when right now.

sirius25y commented 2 years ago

That’s okay. I was just trying this out as I’m new to wrf (and also qgis). I can send you input parameters I used. But it’s practically the same as the tutorial except the centre of domain and projection.

That's fine. The info provided should be enough to reproduce the issue.

letmaik commented 2 years ago

@sirius25y I just tried the tutorial with Mercator and otherwise original domain, which worked and showed the output correctly. I couldn't run wrf with your modified center point because it crashed. If you still have the issue please copy the complete WPS and WRF namelists for reproduction and any more details like versions of software etc.

sirius25y commented 2 years ago

Thanks. I actually did this at work and have since moved on to another job so i no longer have access to the files. I will try to recreate it one time and will see if i get the same result
