[ncl-talk] NCL Error

[Bill Ladwig]

Unfortunately, the wrf_omega routines in V6.2.0 and 6.3.0 have a bug that
produces incorrect values.  Since the error occurs in the C-wrapper code,
there isn't a simple workaround.  This has been fixed in the upcoming 6.4.0
release.

For now, I suggest trying the testing anaconda release of NCL 6.4.0.  It
may not be perfect, but is probably ok for your needs.  First, install
anaconda from:

https://www.continuum.io/downloads

After installing anaconda, to install NCL do:

conda install -c dbrown -c khallock ncl

Hope this helps,

Bill
