Figure 1: Mean and uncertainty values of CALIOP data in the 0–10 km altitude range.

CALIOP Level 1.5 total attenuated backscatter mean (solid red line) and uncertainty (error bars) are shown for closest approach on (a) 13 November 2013, a typical nighttime data set, and (b) 14 January 2014, a typical daytime data set. The along-track averaging distance is 20 km.
