INSTAAR: Detlev Helmig

Fellow and Associate Research Professor of INSTAAR, Univ. of Colorado at Boulder.

Ph.D. 1989, University of Duisburg, Germany.

INSTAAR Directorate Members

Specialty: Surface-Atmosphere Interactions, Atmospheric Chemistry and Transport, Atmospheric Measurement Techniques, Polar Atmospheric Chemistry, Oceanic Gas Fluxes.

Research Interests: 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.

Outstanding Award: Young Investigator Award, U.S. Enviromental Protection Agency, 1996.
