Re: not able to change the lat lon values properly

Hi All,

Thanks for all your responses. setting mpCenterLonF has solved my problem.

To Mary's query, I have uploaded the data file. It is a T382 (1152x576) model output in grib2 format. Hope, lons 0:360.263 is been taken care by ncl properly. Please let me know if I am wrong.

Thanks,
