Stephen Guimond, who has joined GESTAR II from JCET, is a Research Associate Professor with the Physics Department at UMBC and directs the Geophysical Fluid Dynamics (GFD) Group here. Dr. Guimond (UMBC/612) recently had a paper published and a proposal selected. He was the second author on an article led by Gennaro D'Angelo of Los Alamos National Laboratory (LANL), "Contrasting stratospheric smoke mass and lifetime from 2017 Canadian and 2019/2020 Australian megafires: Global simulations and satellite observations," published in J. Geophys. Res. - Atmos., https://doi.org/10.1029/2021JD036249.

Dr. Guimond also is part of an NASA AIST proposal that was selected for funding: "GEOS Visualization And Lagrangian dynamics Immersive eXtended Reality Tool (VALIXR) for Scientific Discovery." According to the proposal team, "Traditionally, scientists view and analyze the results of calculated or measured observables with static 1-dimensional (1-D), 2-D or 3-D plots. In this context, it is very difficult to identify, track and understand the evolution of key features due to poor viewing angles and the nature of flat computer screens. In addition, numerical models, such as the NASA Goddard Earth Observing System (GEOS) climate/weather model, are almost exclusively formulated and analyzed in an Eulerian reference frame with fixed grid points in space and time. However, Earth Science phenomena, such as convective clouds, hurricanes and wildfire smoke plumes, move with the 3-D flow field in a Lagrangian reference frame, and it is often difficult and unnatural to understand these phenomena with data in an Eulerian context." Dr. Guimond added, "This AIST project, VALIXR, will develop a scientific exploration and analysis mixed augmented and virtual reality tool with integrated Lagrangian Dynamics (LD) to provide more in-depth science with the NASA GEOS model." He will be responsible for portions of the LD tool and understanding the value for wildfire smoke plume science.

The VALIXR proposal team consists of PI: Thomas Grubb GSFC/587), Co-Is: Thomas Clune (GSFC/610.1), Steve Guimond, Matthias Zwicker (UMD), Leslie Lait (SSAI/614), and Ruth West (UNT), plus Collaborators: Roger Eastman (UMD) and Don Engel (UMBC/672).

Christoph Keller (610.1/MSU) and team were awarded funding for their proposal "Development of a next-generation ensemble prediction system for atmospheric composition", submitted to NASA's Advanced Information Systems Technology (AIST) call. In addition to Dr. Keller as PI, the team consists of Co-I Patricia Castellano (610.1/GSFC), machine learning expert Jennifer Sleeman (610.1/Johns Hopkins University), and collaborators Steven Pawson (610.1/GSFC) along with NOAA scientists Raffaele Montuoro and Ivanka Stajner.

According to Dr. Keller, "The goal of this AIST project is to develop a new modeling framework to support the real-time simulation of reactive gases and aerosols at very high resolution. The project comprises two science tasks: the implementation of simplified parameterizations for atmospheric chemistry and tracer transport into the GEOS Earth System Model, and the development of an efficient methodology for generating probabilistic estimates of atmospheric composition using state-of-the science machine learning algorithms. The utility of this framework will first be demonstrated in the GEOS Composition Forecast system (GEOS-CF), with a technology transfer to NOAA's next-generation air quality forecasting system planned in a second step."

Abstract: 
Data assimilation is the science, or art, of combining information from observations with numerical models to provide better forecasts, improve models, and improve system understanding. Present-day operational data assimilation is based on linearized methods, such as Ensemble Kalman filters and 3D- and 4DVar, while parts of the atmosphere display highly nonlinear dynamics, such as cloud processes and intense tropical cyclones. Furthermore, current methods rely on assuming Gaussian observation errors, and largely ignore errors in the model equations. In this talk I will discuss exciting new developments in nonlinear data-assimilation, and in using data assimilation to estimate non-Gaussian observation errors and model errors. Furthermore, an example of how data assimilation can be used in combination with a newly developed causal discovery method to unravel the physics of Hurricane Rapid Intensification will be presented.

Biographies:
Sonia Kreidenweis is a University Distinguished Professor of Atmospheric Science at CSU. Her research focuses on characterization of the physical, chemical, and optical properties of atmospheric particulate matter, and the effects of the atmospheric aerosol on visibility and climate. Ongoing laboratory and field studies have investigated the role of particle types and of individual compounds found in particulate matter in the nucleation of cloud droplets and ice crystals and initiation of precipitation.

Peter Jan van Leeuwen is Professor of Data Assimilation and Nonlinear Dynamics in the Department of Atmospheric Science and joined CSU in 2018. Before that he worked at the University of Reading, UK, and at the University of Utrecht in the Netherlands, and served as the Director of the Data Assimilation Research Centre. His research group works on pushing data assimilation into the fully nonlinear regime for atmospheric and oceanic problems. Furthermore, he has developed a fully nonlinear causal discovery methodology to analyze the causal pathways of complex nonlinear processes such as Hurricane Rapid Intensification, cloud dynamics and ocean dynamics. He also explores dynamical systems theory to investigate cloud evolution and cloud aggregation processes, and develops methods to investigate how information flows in complex numerical models to understand how different physical processes communicate with each other.

Fuentes (Note: this talk will be rescheduled at a later date.) 
Dr. Jose D. Fuentes, Professor of Atmospheric Science, Penn State University, will present a talk titled "Arctic Climate Change and Cycles of Trace Gases."  Dr. Fuentes is an Associate Director of GESTAR II. 

Date and Time: To Be Determined

Abstract: 
The Arctic is experiencing the most dramatic environmental changes. Manifestations of such changes are the loss of perennial ice and the formation of thinner, seasonal ice. Such changes are causing a wide range of impacts and feedbacks on regional climate and chemical cycles, including greater amounts of water vapor transport from winter--time leads to the overlying atmospheric boundary layer. Changes in sea ice impact the chemistry and the chemical composition of the lower atmosphere as well as aerosol physical and chemical composition. Therefore, this presentation will describe the features of field campaigns to advance knowledge of emissions, transport, and chemistry of halogens such as chlorine, bromine, and iodine above the snowpack on the tundra near Utqiagvik, Alaska. Field campaigns took place during the last ten years and provided key data sets to assess the influences of atmospheric thermodynamics and turbulence on halogen chemistry and thus estimate the impacts of halogens on the composition of the Arctic boundary layer. Air turbulence and chemistry measurements were made on fixed flux towers above the frozen tundra and on aircrafts.

Biography:
Jose D. Fuentes is a Professor of Atmospheric Science at the Pennsylvania State University where he teaches undergraduate- and graduate-level courses in Micrometeorology, Biometeorology, and Air Chemistry. His research focuses on surface-atmosphere interactions related to emissions, turbulent transport, surface deposition, and chemistry of reactive gases and aerosols. Since 2000, he and his students have investigated the role of the snowpack in the emissions and surface deposition of ozone, halogens, mercury, and aerosols. To complete his field studies, he employs flux towers and tethered balloons which have been deployed at several sites in the Arctic. He has also contributed to the development of numerical models to investigate the chemistry of halogens and the aerosol formation in the Arctic atmospheric boundary layer during the springtime. He serves on many advisory boards, including the Committee on Equal Opportunities in Science and Engineering (CEOSE), which is a congressionally mandated advisory committee to the National Science Foundation. As the current chair of CEOSE, he seeks to identify national strategies to broaden the participation of under-represented groups in science, technology, engineering, and mathematics.
