ESSIC at the 2023 AGU Fall Meeting

Last month, the American Geophysical Union (AGU) held its annual Fall meeting from December 11 to 15. ESSIC scientists presented and attended both virtually and in-person in San Francisco, CA. The following is a sample (not all-encompassing) of the ESSIC/CISESS talks, presentations, and posters given at the event.

ESSIC Launches Seed Grant Program

This week, Earth System Science Interdisciplinary Center (ESSIC) announced the selection of two recipients of the Seed Grant Program (ESGP), a new initiative to provide ESSIC scientists with internal funding mechanisms to carry out innovative research in pilot studies that have the strong potential to lead to future proposals for external funding.

ESSIC at Blue Crab Data Workshop

The Chesapeake Bay Stock Assessment Committee held a Blue Crab Data Workshop from Dec 5-7 to review sources of environmental and biological data that may help model the blue crab population for improving the management of this important marine resource and iconic Chesapeake Bay delicacy. Ron Vogel, ESSIC/CISESS senior faculty specialist, participated in the workshop as a subject matter expert on environmental data sources from satellites to be used in the modeling research.

Figure 1. The local perturbations in observed microwave brightness temperatures from an ascending orbit of (a) MetOp-B AMSU-A channel 14, (b) MetOp-C AMSU-A channel 14, a descending orbit of (c) NOAA-20 ATMS channel 15, and (d) SNPP ATMS channel 15 on January 15, 2022. The black triangle at the center for each panel is the Tonga volcano location. The outermost black-curved lines from the Tonga volcano location correspond to a phase speed of 330 m/s assuming that the perturbation has been generated at the time and location of initial volcanic eruption. From the 2nd outermost black-curved lines to the innermost lines, the phase speeds are 300, 270, and 230 m/s, respectively. The time information in each panel indicates the approximate observation time for the Lamb wave (between 300 m/s and 330 m/s indicated by black right-pointing triangles) and for the lead gravity wave (between 230 m/s and 270 m/s indicated by red right-pointing triangles). Red dots indicate the pixels where the brightness temperature perturbation is larger than 1.2 K.

Satellite Microwave Observations of the Hunga Tonga Eruption’s Atmospheric Waves

ESSIC/CISESS scientists Yong-Keun Lee and Christopher Grassotti are authors on a new paper in Geophysical Research Letters describing the first attempt to perform a detailed analysis of the stratospheric impact of the eruption from satellite microwave observations. The other authors on the paper are Neil Hindley from University of Bath and Quanhua (Mark) Liu from NOAA’s Center for Satellite Applications and Research.

Zhang Presents Her New Book at the CTR Wilson Meeting

ESSIC/CISESS scientist Daile Zhang and her coauthor Ron Holle virtually presented their new
book–Flashes of Brilliance: The Science and Wonder of Arizona Lightning –at the CTR Wilson
meeting on November 16, 2023. They discussed the motivation of writing the book and
introduced the content of each chapter. The audiences were interested in creating
undergraduate level courses and materials based on the book.

ESSIC Featured in Fifth National Climate Assessment

ESSIC Assistant Research Scientist Justin Pflug is an author attributed on the Fifth National Climate Assessment, the U.S. Government’s preeminent report on climate change impacts, risks, and responses. The congressionally-mandated effort provides the scientific foundation to support informed decision-making across the United States. Pflug is attributed on two chapters, “Water” and “Compound Events”.
