Arlyn Andrews leads the Carbon Cycle Greenhouse Gases group within NOAA’s Global Monitoring Laboratory. She has measured carbon dioxide from Earth’s surface to the stratosphere from a variety of diverse platforms, including NASA’s ER-2 aircraft -- a modified U-2 spy plane, high-altitude balloons, and very tall broadcast towers. Arlyn earned her Ph.D. in Earth and Planetary Science from Harvard University in 2000 and then spent a few years at NASA Goddard Space Flight Center, where she contributed to the initial development of concepts for active and passive CO2 satellite sensors.
Arlyn joined the NOAA Global Monitoring Laboratory in 2003 and assumed responsibility for in situ measurements from tall towers within the NOAA Global Greenhouse Gas Reference Network. She developed the NOAA’s CarbonTracker-Lagrange regional modeling framework for estimating greenhouse gas emissions and removals, with a particular emphasis on understanding uptake of carbon dioxide by terrestrial ecosystems. Arlyn has been an active participant in the U.S. Interagency North American Carbon Program since its inception. She served on the Climate Variability and Change panel supporting the Decadal Survey for Earth Science and Applications from Space (ESAS 2017), and she is a member of the NASA Carbon Monitoring System Science Team and the NASA Orbiting Carbon Observatory Science Team.
Andrews plenary talk will discuss development towards an International Reference Network for Greenhouse Gases
Dr Erik Andersson is working at the European Commission's Copernicus Unit, seconded there by the European Centre for Medium-Range Weather Forecasts (ECMWF). While on secondment, Andersson is working on developing Copernicus Services for the monitoring of carbon dioxide (CO2) emissions, focusing on anthropogenic fossil fuel emissions in the context of the Paris Agreement. The CO2 monitoring and validation service will be based on satellite and in-situ measurements. Andersson has a scientific background in data assimilation, the global observing systems, the impact of observations on the quality of forecasts and the use of observations in Numerical Weather Prediction (NWP).
Andersson's plenary talk will discuss the requirements for in-situ observations to support the Copernicus CO2 monitoring service focusing on anthropogenic CO2 emissions.
Christof Gerbig is the leader of the Airborne Measurements and Mesoscale Modeling Group at the Max-Planck-Institute for Biogeochemistry in Jena, Germany. His main interest is to make atmospheric measurements of trace gases relevant for our earth's climate, and to utilize these data in combination with transport models to learn about sources/sinks of those gases, most prominently of CO2. On the experimental side this involves high accuracy measurement of trace gases from airborne platforms, but also development and optimization of such instrumentation. On the theoretical side it involves development of analysis tools such as mesoscale tracer transport models coupled to surface flux models. Gerbig’s plenary talk is titled ”Can we see a covid-19 impact in atmospheric GHGs? A diagnostic assessment using STILT”.
