[ncl-talk] Binning multilevel MODIS data using bin_sum

[Rick Brownrigg]

Hi,

I'm not totally sure, but I wonder if "level" in this line should be "lev"?

bin_sum(GBIN(level,:,:),GKNT(level,:,:),lon,lat \

In any case, a few strategic print() statements on your indexing variables
will show where/when thing go arwy.

HTH...
