Surface-atmosphere interactions; atmospheric chemistry and transport; atmospheric measurement techniques; polar atmospheric chemistry; oceanic gas fluxes.
Biosphere-atmosphere trace gas fluxes and their environmental controls, in particular emissions of biogenic volatile organic compounds (BVOC) from vegetation; atmospheric transport; deposition processes and atmospheric chemistry; polar snow-atmosphere gas exchange processes; development, development and application of analytical tools for field research; urban atmospheres and hazardous pollution; intercontinental atmospheric transport. Current capabilities include atmospheric sampling and monitoring instrumentation, gas chromatography, gas chromatography/mass spectrometry, field methods for BVOC emission studies, eddy correlation techniques, meteorological and chemical instrumentation for flux measurements and boundary layer profiling from tethered balloon platforms.
