Mixing ratio to relative humidity
WebThis allows us to do simple calculations that use the default assumptions. For example, to calculate pressure from virtual temperature and density: >>> import atmos >>> atmos.calculate('p', Tv=273., rho=1.27) 99519.638400000011. Or to calculate relative humidity from water vapor mixing ratio and saturation water vapor mixing ratio (which … WebAtmospheric humidity is a measure of water held in the air as a gas. Water can be solid (ice), liquid (water) or a gas (vapour). The vapour component makes up about 99% of all water held in the atmosphere. The air that we breathe is a mixture of gases - mostly nitrogen (78%) and oxygen (21%) with small amounts of carbon dioxide, argon and water ...
