Black carbon contribution to the aerosol phase and its scavenged fraction in mixed phase clouds at the high Alpine site Jungfraujoch (3580m asl) [PDF]

open access: yes, 2006
The mass fraction of black carbon (BC) in the atmospheric aerosol and its mixing state are important for the direct aerosol climate effect. These properties also determine if BC is incorporated into cloud hydrometeors (i.e. droplets and ice crystals) and

Changing aerosol chemistry is redefining HONO sources

open access: yesNature Communications
Heterogeneous reactions of NO2 on particulate matter have been considered an important source of HONO (Nitrous acid) in the troposphere, whereas its contribution is controversial due to the lack of uptake coefficient of NO2 (γNO2) on the surfaces of ...

Seasonal and spatial variations of global aerosol optical depth: multi-year modelling with GEOS-Chem-APM and comparisons with multiple-platform observations [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2015
Recent AeroCom phase II experiments showed a large diversity in aerosol optical depth (AOD) among 16 detailed global aerosol models, which contributes to the large uncertainty in the predicted aerosol radiative forcing.
