(a) Cryogenic Frost Point Hygrometer (CFH) H2O profile (black) taken from Sodankyla, Finland (67° N), on 7 March 2008, along with the 15 closest-matched Aura Microwave Limb Sounder (MLS) H2O profiles (colored). (b) The difference between the matched MLS profiles and the CFH data. (c) The MLS a priori profiles corresponding to the MLS H2O retrieval values shown in the upper left panel. (d) The CFH data averaged to the MLS resolution using different a priori profiles as input to the procedure described by Read et al. (2007). The black line is based on the CFH as the a priori, whereas the colored lines are the result of using the corresponding colored line from the lower left panel.
