NCL does not handle GRIB2 boustrophedonic scanning

Hello,

It appear that NCL does not handle a complex packing method called boustrophedonic scanning in GRIB2 files. This leads to a "venetian blinds" effect when the attached file is plotted using NCL 5.0.0. IDV and GEMPAK both display the data properly. A workaround for NCL is given below.

dimms = dimsizes(array)
do j=1,dimms(0)-1,2
array(j,:) = array(j,::-1)
end do

Thank you.
