Daytime heating value is used in the formula to calculate mixing height in the PBL. The unit used to represent is Kelvin-Metre.
I have collected vertical air pollutant samples at three different heights close to the road. Meanwhile I observed meteorological data at one particular point i.e. above the building roof during...
