\textbf{JJA}: The dry season shows a clear boundary layer, with a steep gradient in the mixing ratio around 800mb. Probably the result of the descending branch of the Hadley cell being over Darwin during this period. The bias is greatest at the surface (dry) and lower free atmosphere (wet). Here the RH corrections have little impact on the bias between the 2 datasets.  The RH shows similar features in the bias relative to the mixing ratio. However, these is a large wet bias in the UTLS region. Although the RH correction brings the 2 data sources into better agreement, the large positive bias remains. \citet{Wang_2010} show a positive bias for RH in the UTLS for several reanalysis datasets relative to sondes (drift sondes in their case). The temperature profiles show a slightly cool bias in the lower troposphere for the reanalysis (~2^oC). However, a bias this small won't have a large impact on the modeled isotope profiles.
