Mary Barth earned her bachelor’s degree in chemical engineering at the University of Colorado and a Ph.D. in atmospheric sciences from the University of Washington. She is internationally recognized as a leader in the study of clouds and chemistry and led the highly successful NSF/NCAR-NASA Deep Convective Clouds and Chemistry (DC3) field campaign.
Mary’s significant research has focused on examining aerosol sulfate production, studying aerosol-cloud interactions, and investigating the effects of clouds on ozone chemistry primarily using numerical models at different spatial scales. Over the past 15 years, she has focused on thunderstorms and chemistry by conducting numerical simulations coupled with gas and aqueous-phase chemistry to elucidate the processes that control the distribution of chemical species in thunderstorms. Mary also led the high-resolution simulation on a continental domain to examine the effects of the 2006 North American Monsoon on tropospheric chemistry.
She started her research career as an NCAR Visiting Postdoctoral Scientist with the Mesoscale and Microscale Meteorology (MMM)/Atmospheric Chemistry Divisions (ACD). Mary has received numerous awards including NCAR Special Recognition Awards for establishing the Early Career Scientists Assembly and for leading the Deep Convective Clouds and Chemistry Field campaign, as well as the 2015 UCAR Outstanding Accomplishment Award for Diversity.

Martyn received his bachelor’s and master’s degrees from the University of Canterbury in geography and a Ph.D. in geography from the University of Colorado. He has dedicated his career to research at the interface between climate and hydrology. His research spans three main focal areas: 1) developing and evaluating process-based hydrologic models; 2) understanding the sensitivity of water resources to climate variability and change; and 3) developing the next generation of streamflow forecasting systems. He has made major science advances understanding the impacts of climate change on water resources and advancing probabilistic methods for national-domain hydrological modeling.
Martyn’s research on the numerical modeling and prediction of hydrologic processes includes the coupling of hydrology and climate models, development of spatially distributed hydrologic models, development of methods for hydrologic data assimilation, and development of methods to quantify hydrologic model uncertainty. An important recent scientific contribution has been the development of a new hydrologic modeling framework termed SUMMA (the Structure for Unifying Multiple Modeling Alternatives). SUMMA provides multiple options to simulate all dominant biophysical and hydrologic processes from the treetops to the stream, and is particularly useful to characterize uncertainty in hydrologic model simulations, and provide a controlled and systematic approach to land model development.
Martyn started his career at the University of Colorado as a Research Scientist and then worked as senior researcher at the National Institute of Water and Atmospheric Research in Christchurch, New Zealand before coming to NCAR. Recently Martyn received the Editor’s Choice Award, bestowed on the top five papers published in the Water Resources Research journal in a given calendar year.

Mausumi Dikpati

Mausumi earned her master’s degree and Ph.D. in physics from the University of Calcutta and the Indian Institute of Science respectively. Her primary research interests are in the area of hydrodynamics and magnetohydrodynamics of the solar convection zone and tachocline, with particular emphasis on solar dynamo theory and applications of data assimilation to solar prediction problems. Her work on solar flux-transport dynamos has created a paradigm shift in understanding how the solar dynamo operates.
She was the first to build a physical model-based solar cycle prediction scheme based on numerically integrating forward the relevant laws of physics. Recently Mausumi has been one of the pioneers in the application in solar dynamo models, based on the NCAR-DART framework. Currently Mausumi is representing HAO on the NCAR Data Assimilation Initiative committee (NCAR-DA).
Mausumi’s career began as an NCAR Advanced Study Program Postdoctoral Fellow and she has continued her career trajectory within NCAR. Her research on the extended minimum at the end of solar cycle 23 was recognized as one of the top 100 discoveries in 2011 by Discover Magazine. She won the John Firor HAO Outstanding Publication award in 2007 on her first solar cycle prediction paper.

Brian O’Neill

Brian received his master’s degree in applied science and his Ph.D. in Earth systems science, both from New York University. He serves as the Leader of the Community Earth System Model (CESM) Integrated Assessment Modeling Group, co-chairs the CESM Societal Dimensions Working Group, and is the Chief Scientist of the Climate and Human Systems Project. Brian’s field of expertise is integrated assessment modeling of climate change – an inter-disciplinary field that combines knowledge from both the social and natural sciences to address the human dimensions of climate change, from the activities driving emissions and land use to climate’s societal and ecological impacts.

He coordinated the development of the integrated Population-Economy-Technology-Science (iPETS) model, an integrated assessment model of energy, land use, and economy, from its roots as a regional energy-economy model to a global model. He has also provided an international leadership role in the design and development of a new framework for scenarios for climate change research, involving the combination of alternative scenarios of societal development and of climate change outcomes.
Prior to coming to NCAR, Brian developed his research while at the Environmental Defense Fund, Brown University, and the International Institute of Applied Systems Analysis. He has participated as a lead author in assessments of the Intergovernmental Panel on Climate Change and is lead author of the book Population and Climate Change.
