Cloud cycling, scavenging and aerosol vertical profiles: process sensitivity and observational constraints by Kipling, Z

“…</p> <p>Finally, the processes controlling the vertical profile of aerosol are investigated using a series of model-based sensitivity tests, along with the extent to which these processes can account for the large diversity in vertical profiles seen amongst current models. …”

Uncertainty from the choice of microphysics scheme in convection-permitting models significantly exceeds aerosol effects by White, B, Gryspeerdt, E, Stier, P, Morrison, H, Thompson, G

“…Further, we show that the response of the hydrometeors to CDNC perturbations differs strongly not only between microphysics schemes, but the inter-scheme variability also differs between cases of convection. Sensitivity tests show that the representation of autoconversion is the dominant factor that drives differences in rain production between the microphysics schemes in the idealised precipitating shallow cumulus case and in a subregion of the Congo basin simulations dominated by liquid-phase processes. …”

Quantifying the sensitivity of aerosol optical properties to the parameterizations of physico-chemical processes during the 2010 Russian wildfires and heatwave by Palacios-Peña, L, Stier, P, Lorente-Plazas, R, Jiménez-Guerrero, P

“…In order to achieve this objective, sensitivity tests have been carried out, using the WRF-Chem regional fully coupled model by modifying the dry deposition, sub-grid convective transport, relative humidity, and wet scavenging. …”

Constraints on aerosol processes in climate models from vertically-resolved aircraft observations of black carbon by Kipling, Z, Stier, P, Schwarz, J, Perring, A, Spackman, JR, Mann, G, Johnson, C, Telford, P

“…</p><p>Using this methodology, we conduct sensitivity tests on two specific elements of the models: biomass-burning emissions and scavenging by convective precipitation. …”
