Let's say I have a gas in a fixed volume being heated by a uniform, monochromatic light source.
I'd like to know how the radiative heating rate per unit mass of the gas in J/kg/s scales with the density of the gas.
If I wanted to know how the peak temperature of the gas scales with density, then I suppose I'd just do an energy-balance problem given some specification of the input source and properties of the gas. Would a similar approach be used to get at the heating rate that I am after?
I am attempting to model the radiative heating of an air parcel in the atmosphere containing some density of an aerosol, by incident radiation, without actually modeling the chemistry or radiation itself.
