My research group strives to be a world leader in the measurement of volatile organic compounds and the interpretation and synthesis of these measurements in the full context of atmospheric chemistry. A main goal of my research activity is to participate in collaborative efforts to quantify the chemical composition of the atmosphere, characterize how it is changing in response to natural and anthropogenic forcings, and, ultimately, develop the capability to predict changes that may have important implications for the health of the Earth’s ecosystem. I have acquired expertise in the development and deployment of novel instrumentation to measure a suite of volatile organic compounds (non-methane hydrocarbons, oxygenated volatile organic compounds, and CFCs and HCFCs) that directly impact the chemistry of the troposphere and lower stratosphere. I place a special emphasis on the interpretation of these measurements with respect to their impact on cycles of NOx, HOx and halogens. I have led the development of the unique and highly successful Trace Organic Gas Analyzer (TOGA). TOGA quantifies a full suite of the VOCs listed above in near-real-time at unprecedented levels of accuracy, precision and speed on multiple platforms, including the NCAR GV, and C-130 aircraft, as well as the NASA DC-8. Recently I led the development of the Trace Organic Gas Analyzer - Time-of-Flight Mass Spectrometer (TOGA-TOF). This is the most advanced Fast GC-MS TOF instrument in the world. It was recently deployed on the NASA DC-8 for the FIREX-AQ mission. I recently led the development of the WASPP – the NCAR ACOM Whole Air Sampler Pilotless Platform, a unique and versatile atmospheric sampling drone system developed during Lizzy Asher’s ASP Postdoc.

I have been working on stratospheric chemistry and dynamics for about 20 years. My primary interest is exploiting satellite data sets to improve our understanding about the chemical and dynamical processes in the atmosphere. My primary tools are chemical models and statistical techniques to quantify influence of various climate forcers (e.g. Volcanos/solar variability). I also use machine learning to construct long-term gap free datasets.

I lead the Chair for Artificial Intelligence in Climate and Environmental Sciences at KIT. My group works on a diverse set of scientific and methodological challenges in climate science and atmospheric chemistry. For this, we combine machine learning techniques, numerical Earth system models, and Earth observations (e.g., satellite data).

Dr. Gabriele Stiller is an expert for remote sensing of the atmospheric composition. Her scientific interest covers the physics and chemistry of the atmosphere from the upper troposphere to the mesopause. In the last years she has been working on the analysis of the mean meridional circulation of the stratosphere and mesosphere, ozone recovery and water vapour trends in the UTLS, and transport from the troposphere into the stratosphere. She leads the 'Satellite-borne remote sensing of trace gases' group at Karlsruhe Institute of Technology, Institute of Meteorology and Climate Research - Atmospheric Trace Gases and Remote Sensing (KIT/IMK-ASF).

In general terms, my research interest could best be described as data quality assessment, uncertainty estimation and data homogenization with the purpose to study the variation in data series due to climate change processes. I am in particular interested in the variation of water vapour and ozone, both the total column values as the vertical profiles. I developed, applied and compared different correction strategies for vertical profiles of humidity and ozone and I undertook a multi-site intercomparison of total column water vapour measurements at almost 30 sites worldwide by 5 different techniques. Currently, I devote most of my time advertising the use of GPS total column water vapour measurement for climate applications and the controlling the quality assessment of the worldwide network of ozonesonde measurements.

Lisa’s research interest involves atmospheric measurements, modelling studies and laboratory experiments relating to the short-lived radical species OH, HO2 and RO2. She is experienced in using the detailed Master Chemical Mechanism (MCM) to predict radical concentrations for comparison with observations to better understand the chemistry controlling their concentrations in different environments. Her research focusses on understanding the chemistry driving secondary pollutant formation such as ozone as well as understanding the chemistry impacting OH concentrations in remote regions which can impact methane lifetimes. Her research is supported by the National Centre for Atmospheric Science (NCAS)
