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.




The IGAC Americas Working Group and the Caribbean Aerosol-Health Network are pleased to announce a 2018 School of Atmospheric Measurements in Latin America and the Caribbean (SEMLAC).

The school will takes place in conjunction with the 2018 Caribbean Aerosol-Health Network (CAHN) Meeting.

Organizing Committee:


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.


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.
