The V4.51 CALIOP Level 2 products have a number of improvements to the characterization of smoke above clouds, single-shot (333m) cloud clearing techniques, and the stratospheric aerosol classification scheme. Two additional particulate optical depths are computed, derived over both ocean surfaces and above opaque water clouds.

The product is available beginning with data from June 13, 2006, and as of this announcement, through December 31, 2006. Remaining data will be available as it is produced and successfully ingested at the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center.
