Tully, Colin; Neubauer, David; Omanovic, Nadja; Lohmann, Ulrike (2021): Cirrus cloud thinning using a more physically-based ice microphysics scheme in the ECHAM-HAM GCM [preprint], in review. In Atmos. Chem. Phys. Discuss. DOI: 10.5194/acp-2021-685.
"Cirrus cloud thinning (CCT) is a relatively new radiation management proposal to counteract anthropogenic climate warming by targeting Earth’s terrestrial radiation balance. The efficacy of this method was presented in several general circulation model (GCM) studies that showed widely varied radiative responses, originating in part from the differences in the representation of cirrus ice microphysics between the different GCMs. The recent implementation of a new, more physically based ice microphysics scheme (Predicted Particle Properties, P3) that abandons ice hydrometeor size class separation into the ECHAM-HAM GCM, coupled to a new approach for calculating cloud fractions that increases the relative humidity (RH) thresholds for cirrus cloud formation, motivated a reassessment of CCT efficacy."
