The thing is, the density decreasing with height, which is caused by the reduced surrounding pressure, does mean the air is spread out more... but likewise also means the water vapor must take up a larger space for the same amount of molecules too. And so that density/pressure change basically doesn't mean any "more room" for water vapor (the ...

Be aware that vapor capacity in $\pu{g/m^3}$ is property of space and water itself - air is just a spectator here. It grows about exponentially with temperature, typically doubles every $\pu{10^{\circ}C}$. The given absolute humidity in $\pu{g/m^3}$ slightly decreases with temperature ( at the same pressure ) due air thermal dilation. The absolute humidity ...

The wet bulb globe temperature (WBGT) combines 4 or 5 of your variables, while the wet bulb temperature (Tw, or equivalently the heat index, HI) combines only temperature and humidity. This chart from the National Weather Service compares what goes into these measures: Based on your further background information, it could be worth running the model for ...
