Atmospheric Chemist To Present Research At Langley Tuesday
Atmospheric chemist James Crawford will present, "Improving the
View of Air Quality from Space," at 1400 in the Langley Research
Center's Reid Conference Center in Hampton, VA.
Last July, Crawford, NASA researchers and partners, two NASA
aircraft and an extensive ground network, provided an unprecedented
view of air pollution over the Baltimore-D.C. metropolitan area.
This was the first of four field campaigns for a mission called
DISCOVER-AQ (Deriving Information on Surface Conditions from Column
and Vertically Resolved Observations Relevant to Air Quality).
As the principal investigator, Crawford will provide an overview
of current satellite capabilities and how they will be advanced by
the DISCOVER-AQ project. Satellites can observe the total amount of
atmospheric pollutants from the surface to the top of the
atmosphere, but differentiating between pollution near the surface
and miles above is a particularly difficult problem. Scientists,
concerned about high levels of ozone and pollution, are more
interested in what resides at the surface where populations and
ecosystems are exposed to poor air quality.
Research Route of Flight
Crawford, a researcher in NASA Langley's Science Directorate,
has over 20 years of experience in conducting airborne field
studies across the globe to understand atmospheric chemistry and
the changes associated with human activity.
His awards include the Presidential Early Career Award for
Scientists and Engineers as well as NASA's Exceptional Achievement
and Outstanding Leadership medals. Crawford holds a Bachelor of
Science degree in mathematics from the U.S. Military Academy and a
doctorate in atmospheric chemistry from the Georgia Institute of
Technology.
That same evening at 7:30, Crawford will host a similar
presentation for the general public at the Virginia Air & Space
Center in downtown Hampton. This Sigma Series event is free and no
reservations are required.
