Lower Atmosphere

Low tide reveals kelp fields at Arosa (Galicia, Spain)

The troposphere is the lowermost layer of the earth's atmosphere. It extends to about 17 km at the equator and to about 7 km at the poles. This is the region in which most human activities take place. Any changes in this region can affect mankind directly. Hence it is necessary to understand this layer in detail. At Leeds University, several research groups work on different tropospheric chemistry aspects (FAGE and HIRAC).

Our group has done in the past a susbtantial contribution to the understanding of the role of halogens - in particular iodine and bromine- in the gas- and particle-phase chemistry of the Marine and Polar Boundary Layer.

Our activities included field experiments, laboratory experiments and modelling to interpret these.
