Compilation of WRFextraction (WRTOOF)

[hcOnel]

Hi, I am running into some problems while building the WRFextraction tool.

First of all, is it still up-to-date? The README mentions a compressed file and WRFTOOF directory, which don't exist. I assume that the aforementioned directory is WRFextraction itself? Just to make sure, am I correct?

The only thing I change in the Makefile is FC=gfortran. Should I change anything else? (i.e. FCFLAGS is defined twice and such).

Then, I just run make. The module_dm.f90 file I get with the /lib/cpp -C -P module_dm.F > module_dm.f90 command could not be compiled by the gfortran -o module_dm.o -c -O3 -g -I/usr/include module_dm.f90 command, because the header that is commented by /* ... */ in the module_dm.f90 file could not be processed by the gfortran compiler, leading to error:

module_dm.f90:1:1:

 /* Copyright (C) 1991-2018 Free Software Foundation, Inc.
 1
Error: Invalid character in name at (1)

I am not very experienced with pre-processing with cpp and I'm sure that I'm making a silly mistake here, but I'm completely lost and can't figure it out what the Makefile is doing. Any help would be greatly appreciated. Regards, Huseyin

Hi Huseyin, I suggest you take a look at my recent PR on SOWFA-6 repo and check the differences in the makefile.

I went through the same compilation process and after a few hiccups, I managed to get it working using gfortran. My issues, though, were mostly related to the correct path of the netcdf installation. I did run into the problem you are describing here, which is related to the call to make and the temporary file it gets created. If you look the error, it is complaining about c++-style comments, rather than Fortran's !. The makefile in that PR fixes this issue.

Hi Mr. Thedin,

I've run make on your version of WRFextraction and it successfully compiled (despite a few warnings, which I doubt to have any impact). Thanks!

I should also note that I didn't use only the Makefile, I've copied the whole WRFextraction directory from your PR.

Just for the reference, here are the warnings:

Yeah, these warnings can be ignored. Glad it worked!

Hi Huseyin, Thedin,

I have tried the same compile processing with you and got the same warnings. When I run ./wrftoof, the result shows like

opening : flnm(i) 1 wrfout_d01_2015-08-05_05_40_00.nc Dimensions: 1 100 1 109 1 88 WRF grid is clockwise rotated approx. -0.00000 deg. from true lat/lon. Compensating. Getting variables from solution file Have heat flux: T Processing body 1 : west_bc.dat Processing body 2 : east_bc.dat Processing body 3 : south_bc.dat Processing body 4 : north_bc.dat Processing body 5 : lower_bc.dat Processing body 6 : upper_bc.dat End.

My question is that I cannot find the output file in the folder. Does it run correctly or the result is included in other files?

Thank you very much!

Hello, I extracted the boundary but the operation always returns an error as follows:

opening : flnm(i) 1 wrfout_d01_2000-01-24_16:00:00

Dimensions: 1 50 1 50 1 50

Reading latitude/longitude from latlong.nc

The WRF grid is blessings approx. -0.00000 deg. From true Lat /lon.

I feel like it might be because there's a problem with the _bC.dat I extracted. So I would like to ask how to extract the coordinates x,y,z of each boundary point and convert them into longitude/latitude/altitude. Is there a program that can be provided?
