Problem in domain plotting, based on Lambert projection

[prakriti3896]

I was trying to view/plot the domains using PostWRF but when I run ./postwrf.sh I get the following Error:

_PostWRF: Drawing the map of the model domain ...

• The pdf generated does not have any plot, it does show some plotting which is wrong.
• If I select the x11 option the display opens but shows no plot and after that it closes on its own.
• I am able to plot domains using $ ncl util/plotgrids_new.ncl (NCL v6.6.2 is installed using miniconda3)

I am attaching my wps namelist, the plot generated by PostWRF and the plot generated by plotgrid.ncl .

PostWRF can plot the model domains if they are based on the Lambert projection.
In the new versions, this problem will be handled to support other projections as well.

Hello, I am experiencing the same error you are reporting and would like to ask how you solved this last problem when drawing “Mercator projections”?

Hi @XinzhuFang
I am working on this issue. It will be probably solved next week.

Hi,

The question about lambert and mercator projections is related only for plotting model domains and contour plot?
I mean, when I extract data using DATA EXTRACTION (ON SURFACE), the wrfout file need to be in lambert projection?
I'm sending a image to clarify my question.

Congrats for postwrf tool!

Hi @VladimirSobral
All wrfout files with any projection must be plotted by PostWRF without problems. However, the image you inserted looks weird. So for more investigation on your case, you can apply the command below on your wrfout_file and send out.nc to me:
ncks -d Time,1,2 wrfout_file out.nc

[VladimirSobral]

Hi anikfal

Thank you for your reply.
Attached the file out.nc.
Just to inform you about some information of my area:
City's name: João Pessoa - Brazil
Projection of shapefile: WGS 84 25s

@VladimirSobral
It seems you have stored every time slot of the WRF output in a single file. So there is no Time variable in the file. This issue makes some problem for plotting the data.

Try to plot the domains again. I updated it and it should be okay now.
Before trying, git pull postwrf, or clone it again.
