Title

Measuring aerosol-cloud interactions in satellite data

Abstract

Increases in aerosol emissions through human activity are expected to produce smaller cloud droplets, resulting in more reflective clouds and an overall cooling effect on the climate. This change in droplet size has a large number of potential knock-on effects, such as changes in precipitation formation, cloud amount and glaciation temperature. However, large-scale meteorological variability can cause aerosols and clouds to co-vary, obscuring any potential aerosol effect.

This talk demonstrates how aerosols effect can be isolated. Improved statistical techniques allow for a more accurate constraint of processes in atmospheric models, whilst the combination of cloud observations with newly available datasets of ship and aircraft emissions allow aerosol-cloud relationships to be measured at a small scale. This provides a pathway to an improved future understanding of cloud microphysical processes and tighter observational constraints of the human impact on the climate.
