Two Models: AERMOD & ADMS AERMOD ADMS Both “New Generation” models Components are based on similar sets of state-of-the-art algorithms to describe the state of atmospheric boundary layer Bimodal distribution of turbulent vertical velocities for convective conditions. Regulatory model in US & Ontario and Alternative model elsewhere. Regulatory model in UK and Alternative model in US. Allows vertical profiles of wind and temperature to be input. Requires only one level of near-ground observations to be input, but could take the state of the art ABL as input. Contains shoreline module.
