The Arctic is where warming has been strongest over the past century. It is an atmospheric receptor of pollution from the northern midlatitudes continents, as manifested in particular by thick aerosol layers. NASA scientists will be flying over the Arctic to better understand the transport of pollutions and its impact on the Arctic. The Arctic crew is keeping Earth Live posted daily.

Mike Cubison
Mike is a post-doctoral research minion at the University of Colorado working as part of the Jimenez Group in the Coop Institute for research in the Environmental Sciences. Together with group leader, Jose, Mike will be deploying a mass spectrometer on the NASA DC8 to measure the chemistry of the air particles we hope to sample up in the Arctic on the ARCTAS mission.
David Knapp
David Knapp is an associate scientist with the National Center for Atmospheric Research in the community airborne research instrumentation (CARI) group. This group operates a number of experiments studying a variety of gas compounds primarily on aircraft, but occasionally also on the ground.
Micheal D. Obland
Mike began work as a postdoctoral fellow specializing in lidar at NASA's Langley Research Center in Hampton, Va., in June 2007. He works primarily with the High Spectral Resolution Lidar instrument flying on NASA's King Air B-200. Mike started seriously thinking about working for NASA when he participated in the NASA Academy at Ames Research Center as an undergraduate from University of Montana. After completing his bachelor degrees in physics and mathematics, Mike continued on to Montana State University where he finished both his master's and doctoral degrees in physics.
Mike was supported in his doctoral studies by a NASA Graduate Student Researchers Program fellowship wherein he built a lidar that specifically maps out water vapor in the atmosphere. He was also the project manager for building Montana State's first satellite, which was called Montana EaRth-Orbiting Pico-Explorer (MEROPE). It was lost when the Russian rocket carrying it failed to make it into orbit and crashed in the Kazakhstan Desert.
Jennifer Richardson Olson
Jennifer has been an atmospheric chemist in the Science Directorate at NASA's Langley Research Center in Hampton, Va., since 1989, where she is primarily involved in the theoretical analysis of measured tropospheric trace species from airborne platforms. Photochemical box modeling is used to evaluate the detailed photochemical characteristics of species that cannot be directly observed, such as photochemical tendencies and the role of such tendencies in the overall regional budgets of atmospheric constituents. Additional research has encompassed participation in the development of regional air quality modeling systems and global model analysis, and the impact of biomass burning emissions on various environments.
Jennifer was born in Texas City, Texas, and grew up in Santa Fe, Texas. She received a degree in Meteorology from Texas A&M University in 1986, and a Master's Degree in Atmospheric Sciences from Georgia Institute of Technology in 1988. She began working at Langley in 1989, and through their continuing education program, returned to Georgia Tech to receive a Ph.D. in Atmospheric Science in 1994.
Tony Strawa
Tony is the principal investigator for a group of instruments called Aero3X, which are flying on the NASA P-3B aircraft in the ARCTAS mission. The main objective of his work in ARCTAS is to measure the way in which small particles in the air, known as aerosols or particulate matter, interact with sunlight and clouds.
