Simulating gas-aerosol-cirrus interactions: Process-oriented microphysical model and applications

This work describes a process-oriented, microphysical-chemical model to simulate the formation and evolution of aerosols and ice crystals under the conditions prevailing in the upper troposphere and lower stratosphere. The model can be run as a box model or along atmospheric trajectories, and considers mixing, gas phase chemistry of aerosol precursors, binary homogeneous aerosol nucleation, hom...

Microphysical and Dynamical Influences on Cirrus Cloud Optical Depth Distributions

Cirrus cloud inhomogeneity occurs at scales greater than the cirrus radiative smoothing scale (~100 m), but less than typical global climate model resolutions (~300 km). Therefore, calculating cirrus radiative impacts in global climate models requires an optical depth distribution parameterization. Radiative transfer calculations are sensitive to optical depth distribution assumptions (Fu et al...
