[ncl-talk] Question on regridding PATMOS-x data

[Wang Xinyue]

Dear Mary,

Thanks for your reply!

The output is as follows:

XWs-iMac:~ wangxinyue$ which ncl
/Users/wangxinyue/ncl-6.4.0/bin/ncl
XWs-iMac:~ wangxinyue$ ncl -V
6.4.0
XWs-iMac:~ wangxinyue$ env | grep NCARG
NCARG_ROOT=/Users/wangxinyue/ncl-6.4.0
XWs-iMac:~ wangxinyue$ which ESMF_RegridWeightGen
/Users/wangxinyue/ncl-6.4.0/bin/ESMF_RegridWeightGen
XWs-iMac:~ wangxinyue$ ls -l $NCARG_ROOT/bin/​ESMF_RegridWeightGen
ls: /Users/wangxinyue/ncl-6.4.0/bin/​ESMF_RegridWeightGen: No such file or directory

Any solutions for this problem? Thanks.

Best regards,
Xinyue
