Version 4.20r05 PMC data have been replaced with version 4.20r06. The only difference is the addition of “Albedo Ice Regression (AIR)” albedo and ice water content (Thomas et al. (2018), in preparation). These arrays are contained in the standard Level 2 CLD file. The v4.20r06 data set covers the 2007 to 2013 PMC seasons in the northern hemisphere and the 2007–2008 to 2014–2015 seasons in the south. Beyond this point in time the AIM orbit degradation (increasing beta angle) caused the v4.2 retrieval algorithm to become unreliable.
