APARC Leadership
APARC leadership is composed of experts from around the world who dedicate their time to APARC’s international activities. These include the APARC Scientific Steering Group (SSG), who serve to guide APARC’s scientific focus, targeted activities and their leaders, the WCRP Joint Science Committee liaisons, and WCRP Secretariat officer, as well as the the International Project Office.
Current members of the APARC Scientific Steering Group (SSG) are:
Amanda Maycock
University of Leeds, UK
Biography
Amanda Maycock is Associate Professor and Director of the Institute for Climate and Atmospheric Science at the University of Leeds. Her research covers climate variability and change across timescales, atmosphere-ocean interaction, midlatitude dynamics, teleconnections, stratosphere-troposphere coupling and atmospheric composition. Amanda co-led the SPARC activity Atmospheric Temperature Changes and their Drivers. She served as Lead Author of the IPCC WGI Sixth Assessment Report and Co-ordinating Lead Author of the 2018 WMO/UNEP Scientific Assessment of Ozone Depletion and was a member of the US CLIVAR working group on tropical widening. She led the SPARC Task Team to develop the new SPARC Strategy 2022-26.
Olaf Morgenstern
DWD Offenbach, Germany
Biography
Olaf is interested in all aspects of composition-climate interactions. He was a lead developer of the UK Chemistry and Aerosols (UKCA) chemistry-climate model from its inception in 2003. After moving to NIWA in 2008, he has widened his research to cover various aspects of climate, in particular attributing global- and regional scale climate change to anthropogenic and other drivers, and has published extensively on tropospheric composition and climate trends. He has led NIWA’s involvements in the Chemistry-Climate Modelling Initiative and the Aerosol and Chemistry Model Intercomparison Project (AerChemMIP). The latter has informed the 6th Assessment Report of IPCC which he is also a Lead Author of. He is Science Leader Earth System Modelling for the Deep South National Science Challenge, has led several projects for the Deep South NSC, and is presently co-leading the “Modelling Clouds and Aerosols” project.
Karen Rosenlof
NOAA Boulder, USA
Biography
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.
