Dr. Richard Collins
My primary interest is the meteorology of the middle and upper atmosphere and the remote sensing of this region. Working with students at the Lidar Research Lab at Poker Flat Research Range, I develop and operate laser radar (lidar) systems to probe the atmosphere yielding measurements of temperature, density and concentration of species. We also develop the analysis tools for studying these measurements and associated data sets. These studies include the following topics; the aeronomy of the summer polar atmosphere and noctilucent clouds, the thermal structure of the stratosphere and mesosphere, variability and waves in the middle atmosphere, and the impact of the aurora on the upper atmosphere. I have also participated in studies of forest fires, volcanic aerosols, and fish.
Dr. Nicole Mölders
Since 1988, Nicole Mölders been involved in numerical modeling of the physics and chemistry of the atmosphere. She has used mesoscale models to investigate human and natural (e.g. fire, volcanic eruptions, anthropogenic emissions, land-use changes) impacts on weather, air quality and climate. In close cooperation with hydrologists and geologists she coupled a hydrologic and meteorological model and developed an integrative hydrometeorological model. She worked with computer scientists on optimizing chemistry transport models for parallel computers. She led several projects to study ground water recharge, dry deposition of reactive atmospheric trace gases, water availability under changed climate conditions, the impact of land-use changes on evapotranspiration, cloud and precipitation formation, and impacts of various emission sources on air quality and weather. From 1999 to 2001 she was honored as a Heisenberg Fellow for Physical Hydrology, a prestigious award conferred by the DFG. Her scientific career in America dates back to 1989, when she worked as a visiting graduate student at the ASRC of the State University of New York (SUNY) at Albany. In 2000, she worked at the National Center for Atmospheric Research (NCAR) at Boulder, Colorado. In 2001, she joined the University of Alaska Fairbanks (UAF). At UAF, she continues her research direction with special focus on air quality issues of the Arctic and continues teaching activities. Since 1995, in Germany and the United States, she has taught cloud physics, satellite meteorology, physical hydrometeorology, paleoclimatology, parameterization of hydrometerological processes, numerical modeling and parameterization methods, mesoscale dynamics, introduction to computational meteorology and introduction to atmospheric sciences. She is the author of Land-use and Land-cover change - Impact on Climate and Air Quality and one of the authors of the textbook Lectures in Meteorology. She wants to contribute to improving numerical models in order to simulate the water, energy and trace gas cycles appropriately. Doing so will allow policy makers to use model outcomes to assess future water resources, water and air quality and to make reasonable decisions to meet the challenges of the future.
