[ncl-talk] questions on handling the GrADS FILES

[Lyndz]

Hi wujie,

I think the reason for that error is because the ctl file is intended for
reading multiple files.
See this line: *dset ^fcst_phyland125.%y4%m2*

[1] If you want to use cdo, you need to set this to a specific year and
month. Then create a bash script to change that line iteratively for all
the files.

[2] Actually, I asked this question before. You can convert the jra55
grib files to netcdf using the ncl_convert2nc function (
https://www.ncl.ucar.edu/Document/Tools/ncl_convert2nc.shtml)

See this link for my question before.

Hope this helps,

Lyndz
