[ncl-talk] region of interest

[Dennis Shea]

Your script has:

ncl 13>   lat2d = f->Latitude
ncl 14>
ncl 15>   minlat = -87 ; or some val
ncl 16>   maxlat = 76 ; or some val
ncl 17>   minlev = 0
ncl 18>   maxlev = 100 ;
ncl 19>   ii = *ind*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/ind.shtml>(lat2d.ge.minlat.and.lat2d.le.maxlat.and.ii
= *ind* <https://www.ncl.ucar.edu/Document/Functions/Built-in/ind.shtml>
(lat2d.ge.minlat.and.lat2d.le.maxlat

fatal:And: Number of dimensions do not match, can't continue

 *ind* <https://www.ncl.ucar.edu/Document/Functions/Built-in/ind.shtml>
only works on **one-dimensional arrays**. I assume lat2d is
two-dimensions.

You would have to use *ndtooned*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/ndtooned.shtml> and,
subsequently *ind_resolve*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/ind_resolve.shtml>

Further, line 19 would have to be broken into multiple parts.

lat1d = *ndtooned*(lat2d)
ii1d   = *ind*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/ind.shtml>(lat1d.ge.minlat
.and. lat1d.le.maxlat)
ii       = *ind_resolve*(ii1d, lat2d)
printVarSummary(ii)

Then from this sunset, find the level information.
