Hi,
I am using ncl to plot the 532nm Total Attenuated Backscatter data, but on
comparing it with the image available from CALIPSO itself, I find my plot
very noisy (see attached plots).
Besides, the image also appears to have discontinuity at 3 levels, below
8.2km and then upto 20.2 km, and then higher than 20.2 km, which is
coincidentally the regions where CALIPSO data has different vertical
resolutions (30m and 60m and 180 m respectively). The region where vertical
resolution is coarser, the plot appears to be smoother.

I am just using "gsn_csm_contour" to do the contouring with explicit contour
levels.
And I attached the lat and altitude to the variable before plotting.
Looking forward for any suggestion.

Regards,
Prabhakar
