Influence on nucleation on aerosol-climate forcing
From UKCA
UKCA simulations have highlighted the importance of new particle formation in determining the climate forcing from changes in aerosol since the pre-industrial era.
Two pairs of nudged UKCA runs forced by pre-industrial and present-day emissions were carried out with a control run including the usual source of secondary particles from new particle formation in the upper troposphere, and a sensitivity run where this process was switched off, leaving only primary aerosol particles.
