Helene Chepfer is Professor of atmospheric physics at the University Pierre and Marie Curie, Paris, France. She studies clouds, radiation an climate at the Laboratoire de Météorologie Dynamique of the Institute Pierre Simon Laplace. She is strongly involved in the CALIPSO mission, she is a member of the EarthCare European mission advisory group, and she co-proposed a future space-born lidar mission project named MESCAL.
Dr. Matthew CHRISTIENSEN - STFC-RAL
Wednesday 8 – Session 3
Title: Liquid water path controls on cloud albedo
Dr. Christensen specializes in the development of remote sensing products and studies aerosol-cloud interactions using satellite observations. He has a particular interest in ship tracks where he studied them under Jim Coakley and Graeme Stephens at Oregon State and Colorado State Universities, respectively.
Assessment of the aerosol radiative impacts on clouds at global scales is critical for understanding climate change. At the Rutherford Appleton Laboratory and Oxford University where he currently works, he has developed the broadband radiative flux retrieval for ORAC (Optimal Retrieval of Aerosol and Cloud) to examine the global radiative effect of aerosol-cloud interactions using a suite of satellite sensors.
Dr. Cyrille FLAMANT - LATMOS/IPSL, CNRS
Wednesday 8– Session 1
Title: Dust radiative forcing and heat low dynamics
Dr. Cyrille Flamant is a Senior Scientist at CNRS and has obtained his PhD in 1996 and his habilitation in 2007 from the Université Pierre et Marie Curie in Paris. Dr. Flamant has over 20 years of experience in observational work using ground-based, airborne and space-borne laser remote sensing (LIDAR) applied to the topics of atmosphere dynamics-aerosol interactions, including boundary layer processes, dust aerosols lifting and transport processes and dust aerosols radiative impact on atmospheric dynamics in arid and semi-arid regions.
He has been working for over 10 years on the impact of dust in the West African climate. He steered the seminal work conducted on the Saharan Heat Low (SHL) dynamics and its impact on dustiness in the in the framework of the international African Monsoon Multidisciplinary Analyses (AMMA) project. He was the Principle Investigator of the FENNEC project on Saharan climate. Within the AMMA and FENNEC projects, he has led numerous studies related to dust lifting processes in remote Sahelian and Saharan regions, dust aerosol transport across West Africa (from Sudan to Senegal) via the African easterly jet as well as associated to the northward propagation of cold pools (density currents) emanating from deep convective clouds.
Recent studies in which he collaborated evidenced that interannual variability in Sahelian rainfall, as well as surface wind speeds and dust emissions over the Sahara are the result of changes in lower tropospheric air temperatures in the SHL region, linked to changes in water vapor (SWAT feedback). The studies have shown the prominent role for the SHL in the recent increase in Sahelian monsoon rainfall and Saharan dust load decrease in recent years.

Dr. Amber SOJA - NIA / NASA LaRC
Wednesday 8 – Session 1
Title: Biomass burning emissions, injection height and smoke transport
Dr. Amber Soja is currently an Associate Research Fellow at the National Institute of Aerospace, resident in the Climate Science and Chemistry and Dynamics Branches of Atmospheric Sciences at NASA Langley Research Center, where she has served for almost two decades. Her research career in remote sensing began in 1995, working with Aerosol Optical Depth and Sea Surface Temperature data. She focuses on using satellite, Geographic Information System and modeled data as tools to explore the dynamic relationships that exist between fire regimes, fire weather, the biosphere, atmosphere and climate systems.
She has participated in and led numerous ground-based international field experiments in Siberia, where both experimental and wildland fires were examined. Additionally, Soja has worked closely with the Environmental Protection Agency (EPA) to enhance Decision Support tools by leading efforts that led to the incorporation of multiple platforms (NOAA and NASA) of satellite-based fire data in the current National Emissions Inventory, which demonstrates her ability to lead and to transfer science to applications.
Additional work has included estimating ground-based fire emissions for use in the Realtime Air Quality Modeling System (RAQMS) chemical transport model during the INTEX-A, INTEX-B, TexAQS and ARCTAS field campaigns. Most recently, she took a part-time position as an Associate Program Manager at NASA Headquarters in the cross-cutting Applied Sciences Program, Wildland Fire Applications, where she manages and analyzes the progress of projects and identifies risks, works towards developing NASA interagency partnerships and aides in strategic programmatic planning.
Dr. Trude STORELVMO - Yale University
Wednesday 8 – Session 3
Title: Observational constraints on mixed-phase clouds imply higher climate sensitivity
Dr Storelvmo is an atmospheric scientist, whose research is focused on aerosol-cloud-climate interactions, using mainly a combination of numerical models and satellite observations.

Her research group at Yale currently works on a variety of topics covering a range of scales, from aerosol effects on local storms to the role of dust-cloud interactions in global climates of the past, present and future. Recent studies have also focused on new ways to constrain Earth’s Climate Sensitivity.

Dr. Jean-Paul VERNIER - SSAI/NASA Langley Research Center
Wednesday 8 – Session 1
Title: 10 years of volcanic aerosol observations from CALIPSO
Dr. Vernier earned his Ph.D. from the University of Versailles (France) in 2010 using balloon measurements and satellite observations for investigating the distribution of aerosols in the Upper Troposphere and Lower Stratosphere (UT/LS). His research relied significantly on CALIPSO lidar measurements in developing algorithm for retrieving stratospheric aerosols (Vernier et al., 2009). His work provided better understandings of the role of mid-size tropical volcanic eruptions in supplying the stratosphere in aerosols (Vernier et al., 2011b), which may have mitigated the impact of global warming by 25% between 2000 and 2010 (Solomon et al., 2011).
Between February 2010 and January 2012, Dr. Vernier was supported as a NASA Postdoctoral Fellow at Langley Research Center (Hampton, VA) and has continued his research on UT/LS aerosols and dynamics with CALIPSO (Vernier et al.,2011c) and other satellite platforms. Recent results of his work highlight the discovery of a recurrent Asian Tropopause Aerosol Layer associated with the Southeast Asian monsoon (Vernier et al., 2011a). Since February 2012, Science Systems and Applications, Inc. recruited Dr Vernier as a Senior Research Scientist to continue his research activities on stratospheric aerosol and to prepare the validation of the future SAGE III mission on the International Space Station. He recently won the 2013 award for the best science paper at NASA Langley.

Title: CALIPSO reveals connections between distinct ecosystems via dust intercontinental transport and deposition
Dr. Hongbin Yu is a senior research scientist at the Earth System Science Interdisciplinary Center of the University of Maryland and works in the Climate and Radiation Laboratory of NASA Goddard Space Flight Center.
