[ncl-talk] How to extract the variable CLDFRA

[Lyndz]

Hi,

Have you look at:

https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml

Not in the wrfout? Is this a post process file or the output from the
wrf.exe?

If it is not there in your output file you can calculate it using the
wrf-python functions.

See these links:
https://wrf-python.readthedocs.io/en/latest/user_api/generated/wrf.cloudfrac.html
https://wrf-python.readthedocs.io/en/latest/internal_api/generated/wrf.g_cloudfrac.get_cloudfrac.html
https://buildmedia.readthedocs.org/media/pdf/wrf-python/1.0a3/wrf-python.pdf

If you still have questions about the computation above, just ask wrf-help.

Hope this helps.
