Apparent temperature is the "feels like" temperature, also sometimes referred to as a "heat index" in the summer or "wind chill" in the winter. This is calculated from near surface air temperature, relative humidity, and wind speed.
Right now our CMIP6 holdings have near surface air temperature (tas), near surface specific humidity (huss), and surface wind (sfcWind) available for most models/scenarios.
We can convert specific humidity to relative humidity like so:
Find the saturation point using the formula: saturation point = 6.11 x 10^{7.5 x air temp} / {237.3 + air temp}
Find the relative humidity using the formula: relative humidity = (specific humidity) / (saturation point) x 100
Then use relative humidity to calculate the apparent temperature.
