Hydrates n1-n4

Figure 1. Averaged CN (r>0.003–0.01 μm) and temperature profiles observed (a, b) above Laramie,Wyoming (41°N) for 1982–2012 and (c, d) above McMurdo Station, Antarctica (78°S) for 1986–2010.The data are seasonally averaged for Laramie and monthly averaged for McMurdo according to the legendsin Figures 1a and 1c. The shaded areas indicate the 10 to + 35% uncertainty in the CN measurement, asdiscussed in the text, as well as a ± 0.5°C uncertainty for the temperature measurements.

Figure 7. (a) Ambient temperature (black solid), H2O mixing ratio (purple solid), and midlatitude (brownsolid) and derived polar H2SO4 vapor density (brown dashed) profiles used for themodels. A balloon-bornehygrometer H2O mixing ratio measurement (purple dotted) is also shown for comparison in Figure 7a. (b)CBHN model runs based on two hydrated model formulations (red: J-V-M; blue: Noppel), compared to theCN observation (r>0.003–0.01 μm) at McMurdo on 940817 (plus symbols). In Figure 7b, the solid anddashed lines represent the CBHN calculations using the midlatitude and derived polar H2SO4 vapor densityprofiles, respectively.
