Research:
My research is on studying
the composition of the troposphere
using satellite and in-situ observations
(e.g. aircraft and ground-based measurements taken during field campaigns)
in conjunction with regional and
global atmospheric models. I am addressing
the link between local pollution
processes and regional and global
pollution in my current work.
Gases and aerosols emitted from local human
activities, in addition to natural
sources, might change atmospheric composition on inter-continental or even global scales
coupled through mixing, transport and chemical transformation.
This makes local air quality
a global issue and, as further
consequence, also a factor in climate
change. Air quality issues are also linked
to public policy applications because many of
the pollutants emitted by human
activity are known to have
detrimental impacts on health and
natural and managed ecosystems with a direct bearing
on human welfare and environmental
quality.
Current research topics include e.g. the intercontinental
transport of pollution across the Pacific and
how it impacts
regional and local air quality
over North America, summertime ozone in the
Colorado Front Range, the impacts
of boreal wildfires on air
quality and climate, or the
feedbacks between changes in climate,
weather and air quality.
