IGACnews engages and informs the international atmospheric chemistry community by providing information on IGAC Activities through Workshop Summaries, Activity Updates, and Scientific Features. In addition each issue of IGACnews profiles an early career scientist. The Open Submission section allows non-IGAC Activities related to atmospheric chemistry to publish Workshop Summaries, Activity Updates, Scientific Features, and Editorials. IGACnews is typically published three times per year. The next deadline for submissions to the Jul/Aug 2019 IGACnews is 19 July 2019. Please send submissions to email@example.com.
