Lucy Carpenter is professor of physical chemistry at the University of York and director of the Cape Verde Atmospheric Observatory (CVAO). Her group studies the complex interaction between the oceans and the atmosphere, in particular the chemistry of reactive halogens, organic carbon, and reactive nitrogen. Her work on oceanic and atmospheric halogens has established this chemistry as an important component of tropospheric ozone cycling and makes use of gas chromatography–mass spectrometry (GCMS).

She helped establish the Cape Verde Atmospheric Observatory, one of a few dozen World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) stations worldwide which monitor climate and air quality gases over long time scales, and was a lead chapter author of the WMO/United Nations Environment Programme (UNEP) 2014 scientific assessment of ozone depletion.

After a PhD in Atmospheric Chemistry at the University of East Anglia (UK), Alfonso Saiz-Lopez spent five years working at the NASA Jet Propulsion Laboratory, Harvard-Smithsonian Centre for Astrophysics, and the National Centre for Atmospheric Research. He returned to Spain in 2009 to found the Department of Atmospheric Chemistry and Climate at the Spanish National Research Council (CSIC). His group´s multidisciplinary research combines experimental field measurements of present and past (ice cores) global atmospheric composition, quantum chemistry, and computational Earth system modeling to study atmospheric chemistry-climate interactions.

Anoop Mahajan is an atmospheric chemist working on sea-air interactions and the effect of ocean emissions of trace gases on the atmosphere and climate. He is currently based at the Center for Climate Change Research, Indian Institute of Tropical Meteorology, where he heads a group on chemistry-climate interactions.  He completed his PhD from the University of Leeds, UK and conducted post-doctoral research at Institute of Physical Chemistry Blas Cabrera, Madrid (IQFR), CSIC, before moving back to India in 2012. He has participated in more than 25 international projects, including in the Southern Ocean, Antarctic and Arctic. He is on the Surface Ocean Lower Atmosphere Study (SOLAS) executive committee. He is also involved with the Indian Southern Ocean program, and was the leader of the last Indian Scientific Expedition to the Southern Ocean (ISESO). Over the last few years, he has been working on understanding methane variability over India and its emissions and atmospheric chemistry.
