Atmospheric composition and structure of HD209458b [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractTransiting planets like HD209458b offer a unique opportunity to scrutinize their atmospheric composition and structure. Transit spectroscopy probes the transition region between the day and night sides, called the limb. We present a re-analysis of existing HST/STIS transmission spectra of HD209458b's atmosphere.

Sesquiterpenes dominate monoterpenes in northern wetland emissions [PDF]
Atmospheric Chemistry and Physics, 2020 We have studied biogenic volatile organic compound (BVOC) emissions and their ambient concentrations at a sub-Arctic wetland (Lompolojänkkä, Finland), which is an open, nutrient-rich sedge fen and a part of the Pallas-Sodankylä Global Atmosphere Watch ...

Undetected biogenic volatile organic compounds from Norway spruce drive total ozone reactivity measurements [PDF]
Atmospheric Chemistry and Physics, 2023 Biogenic volatile organic compounds (BVOCs) are continuously emitted from terrestrial vegetation into the atmosphere and react with various atmospheric oxidants, with ozone being an important one.

Automated identification of local contamination in remote atmospheric composition time series
Atmospheric Measurement Techniques, 2022 . Atmospheric observations in remote locations offer a possibility of exploring trace gas and particle concentrations in pristine environments. However, data from remote areas are often contaminated by pollution from local sources.
