Neil Harris

Co-chair of the SSG. Neil is Professor of Atmospheric Informatics at Cranfield University. He obtained his PhD in Chemistry at the University of California in Irvine in 1989 and then joined the European Ozone Research Coordination Unit in Cambridge, UK, where he was a NERC Advanced Research Fellow in the Dept of Chemistry until March 2016. He was a Chapter Lead Author on the 1994 and 2014 WMO/UNEP ozone assessments and is a co-editor of Atmospheric Chemistry and Physics. He has served as a SPARC Activity leader for the SI2N initiative, 20 years after doing similarly for the first SPARC Assessment Report. His research interests include measurements of atmospheric halocarbons, the Tropical Tropopause Layer and emissions of trace gases as well as analyses of ozone trends.

Judith Perlwitz

Co-chair of the SSG. Judith is a Senior Scientist at NOAA and CIRES. She is an expert in atmospheric dynamics, climate diagnostics, and climate attribution. Her background also includes expertise in dynamical interaction of the troposphere and stratosphere, their role in climate and climate change, and chemistry-climate interactions. She participated in recent IPCC and Ozone Assessments as lead and contributing author.

Gufran Beig

Gufran works as Project Director at the Indian Institute of Tropical Meteorology, Pune, India. His area of research is atmsopheric chemistry and air pollution. He developed India’s first air quality forecasting project “System of Air Quality and Weather And Research” (SAFAR) and contributed to the assessment of its impact on human health and food security. Specific topics of expertise include long term changes and trends in the troposphere and stratosphere and hemispheric transport of chemical constituents.

Wen Chen

Wen obtained his PhD in the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences (CAS) in 1994. Currently he is director of the Center for Monsoon System Research at IAP/CAS. And he is also an adjunct professor at the University of the Chinese Academy of Sciences. His research interests include East Asia monsoon climate, atmospheric circulation and teleconnection patterns, stratosphere-troposphere dynamical coupling, and different types of El Niño and their effects on climate. He also served on several national review panels including the National Natural Science Foundation of China – CAS advisory panel that define future priorities in atmospheric science and climate change research.

Harry Hendon

Harry is senior principal research scientist and Climate Processes team leader at the Bureau of Meteorology (BoM), Melbourne. His research focuses on mechanisms and predictability of climate variability from weeks to decades and contributes to the development of the BoM seasonal forecast systems.  He has a focus on variability, predictability and impacts of organized tropical convection, including the interaction of the QBO with the MJO, and on the Southern Annular Mode, including the role of coupling with the stratosphere.  He is a member of the WWRP/WCRP Subseasonal-to-Seasonal Prediction Project Steering Group and previous co-chair of the WCRP Asian-Australian Monsoon Panel.

Nathaniel Livesey

Nathaniel is currently the Principal Investigator for the Microwave Limb Sounder (MLS) instrument on the Earth Observing System Aura spacecraft, launched in 2004. His research interests are centered on microwave space based observations of the chemistry, hydrology and dynamics of Earth’s atmosphere. Most of his work has focused on the MLS experiments both on Aura and the earlier Upper Atmosphere Research Satellite (UARS) launched in 1991. Before becoming Aura MLS PI, he was responsible for the MLS ‘retrieval’ algorithms. These convert the raw observations of the microwave signature of the atmosphere into measurements of atmospheric composition, temperature, humidity, and cloud ice

Karen Rosenlof

Karen is a Program leader and  Senior Scientist for Climate and Climate Change at NOAA/ESRL. Her expertise is in interpretation of stratospheric constituent, aerosol, and temperature data. She is an author of 111 peer-reviewed journal publications. She co-chairs the SPARCs upper troposphere and stratosphere Water Vapor Assessment (WAVAS-II), served as lead author in the first SPARC water vapor assessment and participated in SPARC ozone trends and temperature activities. She is co-author for WMO/UNEP Scientific Assessments of Ozone Depletion; a reviewer and contributing author for IPCC, and a lead author for a GRUAN Network Expansion report.

Kaoru Sato

After spending five years as assistant professor at the Kyoto University and six years at the National Institute of Polar Research (NIPR) in Japan, and – as a visiting scientist – five summers at the North-West Research Associate in Seattle, USA, Kaoru Sato is now professor at the Department of Earth and Planetary Science, University of Tokyo, Japan. Her main research interest is atmospheric dynamics. Her research approach is a combination of theoretical, and high-resolution observation and modeling studies to examine the hierarchical structure and interaction of atmospheric phenomena. She has also served as a visiting professor at NIPR and led the program of the Mesosphere-Stratosphere-Troposphere/Incoherent Scatter radar in the Antarctic (PANSY).

Hauke Schmidt

Hauke is deputy director of the department “Atmosphere in the Earth System” and head of the “Middle and Upper Atmosphere” group at the Max Planck Institute for Meteorology in Hamburg. He has studied various aspects of atmospherics dynamics and chemistry from the surface to the thermosphere and led the development of the “Hamburg Model for the neutral and ionized atmosphere” (HAMMONIA). His current work concentrates on understanding the response of the middle atmosphere to natural and anthropogenic forcing and the role of vertical coupling for this response. The interest in effects of solar variability and of large volcanic eruptions has prompted him in recent years to also work on potential consequences of suggested climate engineering.

Seok-Woo Son

Seok-Woo is an associate professor at the Seoul National University, Republic of Korea, primarily working on the large-scale atmospheric dynamics, upper troposphere-lower stratosphere processes, and stratosphere-troposphere dynamical coupling. He has been actively involved in the SPARC projects such as the CCMVal2, DynVar, and SNAP, and co-authored the WMO ozone assessment reports in 2010 and 2014. He has been (co-)convening SPARC-related sessions in the AGU and EGU meetings and is interested in regional activities in Asia.

Donald J. Wuebbles

Don is Professor of Atmospheric Science at the University of Illinois. He is an expert in atmospheric physics and chemistry, with over 500 scientific publications related to the Earth’s climate, air quality, and the stratospheric ozone layer. In addition, he has co-authored a number of policy-relevant scientific assessments, including as a coordinating lead author for the 2013 IPCC report on the science of climate change, the 2014 U.S. National Climate Assessment, and the 2014 WMO assessment on stratospheric ozone.

Tianjun Zhou

Tianjun Zhou leads the development of the FGOALS climate system model at the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), Institute of Atmospheric Physics, Chinese Academy of Sciences. He is also an adjunct professor at the University of the Chinese Academy of Sciences. His personal research focuses on coupled atmosphere-ocean modelling, climate dynamics, climate change and variability, with particular emphasis on East Asia and the monsoons. Tianjun was co-chair of the CLIVAR Asian-Australian Monsoon Panel (AAMP) from 2013 to 2014 and is currently a member of the GEWEX/CLIVAR Monsoons Panel, and a member of GEWEX GDAP. He also served as Lead Author of chapter 14 of the IPCC WG1 AR5.

Boram Lee

Boram Lee is Senior Scientific Officer and SPARC liaison at the WCRP Joint Planning Staff. Before joining the WCRP she worked at the WMO’s Marine Meteorology and Oceanography Programme, being responsible for the international coordination of marine affairs including coastal risk forecasting and warning systems. In addition to her management tasks, her experience comprises several research and development projects in marine meteorology and associated applications for coastal disaster risk reduction. Boram holds a Ph.D. in climatology from the Université Paris VI, France, and since 2010, she serves as adjunct professor in the College of Ocean Science at Jeju National University, Republic of Korea.
