Inverse modeling of black carbon emissions over China using ensemble data assimilation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Emissions inventories of black carbon (BC), which are traditionally constructed using a bottom-up approach based on activity data and emissions factors, are considered to contain a large level of uncertainty.

Prediction of size-resolved number concentration of cloud condensation nuclei and long-term measurements of their activation characteristics

open access: yesScientific Reports, 2017
Atmospheric aerosol particles acting as cloud condensation nuclei (CCN) are key elements in the hydrological cycle and climate. To improve our understanding of the activation characteristics of CCN and to obtain accurate predictions of their ...

The local ship speed reduction effect on black carbon emissions measured at a remote marine station [PDF]

open access: yesAtmospheric Chemistry and Physics
Speed restrictions for ships have been introduced locally to reduce the waves and turbulence causing erosion, and safety hazards, and to mitigate the air and underwater noise emissions. Ship speed restrictions could be used to minimize the climate impact
