Aerosol-radiation interaction results in heating rates that can in turn modify the planetary boundary layer (PBL) structure. We have set up a single column model (SCM) with an enabled aerosol-radiation interaction in order to perform a large number of numerical simulations. The vertical structures of PBL (e.g., stratification, inversion characteristics) and aerosol (e.g., peak concentration, shape of the vertical distribution) in addition to aerosol type are all control parameters that play a role in the PBL response to aerosol-radiation interaction.
We have carefully mapped out the parameter space and performed thousands of SCM simulations to observe PBL evolution compared to control runs without aerosols. Under certain circumstances, the aerosol-radiation interaction can result in either increasing or decreasing PBL height. Moreover, the results are also aerosol-type specific. In this presentation, we discuss our findings and consequences of aerosol-radiation interaction on the PBL structure and signal propagation.
