Atmospheric trace gas measurements in the tropics by ground-based FTIR-spectrometry — •Thorsten Warneke¹, Justus Notholt¹, Voltaire Velazco¹, and Otto Schrems² — ¹Institute of environmental physics, University of Bremen, Bremen — ²Alfred Wegener Institute, Bremerhaven

The tropics play a central role in global climate. Emissions within the tropics, especially from biomass burning, contribute substantially to the global budgets of many important trace gases. These pollutants significantly influence tropospheric and stratospheric chemistry. Solar absorption-FTIR measurements have been performed in Paramaribo (Surinam) to study the composition of the whole atmosphere, including the Tropical Tropopause Layer (TTL) and the stratosphere.
