Jim Crawford received his B.S. in Mathematics from the United States Military Academy in 1986 and his Ph.D. in Atmospheric Chemistry from the Georgia Institute of Technology in 1997. Since that time, he has been a research scientist at NASA’s Langley Research Center. From the start of his graduate studies in 1991 and throughout his career, his research has been associated with airborne field studies conducted across the globe by NASA’s Tropospheric Chemistry Program and collaborating partners.



IGAC has a strong focus on engaging the next generation of atmospheric scientists through its early career program.  These scientists join an international network early in their career that creates relationships that facilitate atmospheric chemistry research at an international level for years to come.

IGAC cultivates the next generation of scientists by:


Hiroshi Tanimoto is the Head of Global Atmospheric Chemistry Section at National Institute for Environmental Studies (NIES) in Tsukuba, Japan. He received his PhD in Chemistry from The University of Tokyo in 2001 and was a visiting scholar at Harvard University during 2007–2008. Dr. Tanimoto has been working in the field of atmospheric composition in Asia and Oceania regions.



Mark Lawrence is a scientific director of the cluster “Sustainable Interactions With the Atmosphere” (SIWA) at the Institute for Advanced Sustainability Studies (IASS, www.iass-potsdam.de) in Potsdam, Germany.



Fostering collaborative, interdisciplinary research on Arctic air pollution and its interactions with the Earth system and human societies


This working group is brand new in 2018 and is being founded in order to:

  • Provide a forum for scientists to discuss particular challenges in understanding the Southern Hemisphere atmosphere &
  • To foster stronger collaborations between Southern Hemisphere research groups.

Current Activities:


With the view that improving the understanding of atmospheric science in Africa would have large impacts on key societal issues for the continent (e.g. air quality, human health, agriculture, climate change), the African Group on Atmospheric Sciences (ANGA) working group has been established and is under development.


The goals of the new AMIGO (Analysis of eMIssions usinG Observations) project of IGAC is to organize the international scientific community around a synthesis of research using observations-based analysis techniques that aim to better quantify emissions. The synthesis will consider chemically active compounds and greenhouse gases and will evaluate the consistency of their inferred emissions. AMIGO will assess the ability of different analysis techniques to provide consistent quantification of the emissions of multiple species across a range of spatial and temporal scales.


Overarching Objective:

Develop and implement a global air pollution monitoring, analysis, and prediction system for air quality with downscaling capability in regions of the world affected by high levels of atmospheric pollutants, in particular Asia, Latin America, and Africa.
