Some models simulate a secondary maximum at around 100 - 200 hPa, with concentrations much lower than the maximum near the surface; this is primarily due to condensation of semi-volatile SOA at low temperatures but also due to OA accumulation above clouds, where dry and wet deposition is absent.

The temperature (water vapor pressure) trends averaged over all stations were 0.30 (0.07), 0.24 (0.06), 0.13 (0.11), 0.11 (0.07) C / decade (hPa / decade) in the winter, spring, summer and autumn seasons, respectively.

Alternatively look at temperatures at 850 hPa where the bulk of the moisture condenses or the actual areas of those high pressure cells.

While I haven't tried this experiment myself, I foolhardedly predict that the resulting mixture will start out as supersaturated air at temperature 280 K and pressure 620 hPa with RH = 200 % (anyone who cares will have no trouble verifying this using only the specific heat numbers I've given earlier, no thermodynamic needed), and (more importantly for thermodynamics) that it will in due course become air at T = 287.7 K and P = 634.5 (higher pressure) with RH = 100 %.
