What information is provided by the Feature_Classification_Flag(s)?

Why does the surface occupy multiple range bins in the Vertical Feature Mask (VFM)?

Are layer boundaries and layer type information provided in the CALIOP profile products?

What's the difference between volume depolarization ratios and particulate depolarization ratios?

In the profile products what is the difference between 'attenuated backscatter' and 'backscatter'?

The file name of the 5 km layer products would seem to indicate that features are reported at 5 km, but in those files there are features reported at 20 and 80 km, what's up with that?

I have discovered, at least in the 5 km cloud layer files, that the top of the second cloud layer is often higher than the bottom of the first (top) layer. Can you explain to me what this means?

In the layer products the data set Number_Layers_Found indicates that there are N (e.g. 3) layers in a column, does that mean there are N (e.g. 3) unique atmospheric layers in the column?

When I plot the lidar level 1B profile data, why are there discontinuities at ~8 km and again at ~20 km?

Why are there negative attenuated backscatter values in the L1 lidar data? (Aren't these values completely non-physical???) Are these negative values removed before calculating the Level 2 Column Integrated Backscatter?
