Jean Paul Vernier
He earned his Ph.D. from the University of Versailles, France in 2010 by using
balloon measurements and satellite observations to investigate the distribution of
aerosols in the Upper Troposphere and Lower Stratosphere (UT/LS). This relied
significantly on lidar measurements from CloudSat and from the Cloud-Aerosol
Lidar and Infrared Pathfinder Satellite Observation (CALIPSO). This improved
understanding of the role of mid-size tropical volcanic eruptions in supplying the
stratosphere in aerosols which may have mitigated the impact of global warming
by 25% between 2000 and 2010.
Between February 2010 and January 2012, he was a NASA Postdoctoral Fellow
at the Langley Research Center, Hampton, VA and has continued his research on
UT/LS aerosols and dynamics with CALIPSO and other satellite platforms. His
recent results highlight the discovery of a recurrent Asian Tropopause Aerosol
Layer (ATAL) associated with the Southeast Asian monsoon. He was hired as a
Senior Research Scientist by Science Systems and Applications, Inc., in February
2012 to continue his research activities on stratospheric aerosol and to prepare the
validation of the future SAGE III mission on the International Space Station.
