My research deals with the life-cycle of atmospheric aerosols and
their interactions with clouds.
There are two main motivations for studying aerosols and clouds.
One, there is a concern that particles, especially in urban areas, are
harmful to humans. Two, aerosols is a very important component in our
climate system and any changes in the properties of the aerosol may affect the
climate. The importance of aerosols, in terms of an impact on the climate, is on
the same scale as the greenhouse effect by increasing carbon dioxide.
Particles are formed, transformed and eventually removed from the
atmosphere. The processes controlling these steps of the life-cycle are what we
study. We do this by simulating processes in numerical models or observing
aerosol and cloud properties at different locations and environments around the
world covering the altitude range from the ocean surface up to, and even into,
the stratosphere using aircraft. Often our research is conducted as part of
My own honest motivation for studying aerosols and clouds is
simply because I’m curious about how it all works. Think of it, an aerosol is so
small that it is barely visible in a microscope, but yet it influences cloud
systems so large that they can only be seen in its entire from space.
