Annika Jersild, ESSIC Visiting Assistant Research Scientist, is first author on a new paper in Geophysical Research Letters titled “A Spatially Explicit Uncertainty Analysis of the Air-Sea CO2 Flux From Observations”.
ESSIC Research Scientist Dorothy Hall is first author on a new paper in Geophysical Research Letters titled “Snowfall Replenishes Groundwater Loss in the Great Basin of the Western United States, but Cannot Compensate for Increasing Aridification”.
CISESS Deputy Director and ESSIC Research Professor Ernesto Hugo Berbery is a co-author on a new paper in npj Climate and Atmospheric Science, a Nature Research journal, that examines agricultural flash droughts worldwide and reveals their characteristics and life cycle.
The National Weather and Climate Prediction Center (NCWCP) and UMD’s Earth System Science Interdisciplinary Center (ESSIC) held a three-day mini-conference from February 27 to 29, a hybrid event held both at the ESSIC and online. The conference brought together ESSIC, CISESS, and NOAA scientists to share their presentations and posters from the recent AGU and AMS conferences. Peter Beierle was the conference organizer for UMD.
ESSIC Visiting Associate Research Professor Ariana Sutton-Grier has contributed to a chapter in a new book titled Beneficiaries, Equity, and Trade-Offs in Estuarine and Coastal Ecosystem Services. Sutton-Grier contributed to a section on blue carbon.
The global ocean has been heating up for decades, with records from the 1960s reporting a substantial rise in upper ocean heat content. Rising ocean temperatures also affect ocean currents, though there has yet to be a consensus on the strength or extent of those changes, or whether these changes will continue in the future. However, a new paper led by Earth System Science Interdisciplinary Center (ESSIC) scientist Alexey Mishonov documents, for the first time, a significant slowing of the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current system that plays a vital role in regulating Earth’s climate.
Dr. Fernando Miralles-Wilhelm, former director of Earth System Science Interdisciplinary Center (ESSIC), has been appointed the next president of the University of Maryland Center for Environmental Science (UMCES).
ESSIC/CISESS scientist Alexey Mishonov is one of the authors of the newly released World Ocean Atlas 2023. The World Ocean Atlas 2023 (WOA23) is a set of temperature, salinity, oxygen, phosphate, silicate, and nitrate means based on profile data from the World Ocean Database (WOD). WOA23 includes approximately 1.8 million new oceanographic casts added to the WOD since WOA18’s release, as well as renewed and updated quality controls. The database can be used to create boundaries and/or initial conditions for a variety of ocean models, verify numerical simulations of the ocean, and corroborate satellite data.
ESSIC/CISESS scientists Yong-Keun Lee and Christopher Grassotti are co-authors on a new paper in Remote Sensing led by first author Zichao Liang, a student who interned with the MiRS team during the summer of 2023. NOAA scientists Lin Lin and Quanhua Liu also co-authored the paper. The paper, titled “Machine Learning-Based Estimation of Tropical Cyclone Intensity from Advanced Technology Microwave Sounder Using a U-Net Algorithm”, assesses the use of the U-Net model to estimate surface wind speed and surface pressure over pure ocean conditions.
During its one-year funding period, this CISESS Seed Grant project expanded the work of the student-oriented CISESS Remote Sensing Laboratory by building equipment for post-launch radiometric validation using in situ measurements of reflective solar band calibration. ESSIC/CISESS Scientist Xi Shao, along with Sirish Uprety, Tung-Chang Liu, and Xin Jin, developed a Robotic Hyperspectral Ground Bi-directional Reflectance Distribution Function (RHG-BRDF) measurement system. Once built, they worked with three undergraduate students to perform field hyperspectral measurements of different ground targets. The student also developed python modules for converting measurements to hyperseptral reflectance, data visualization and analysis.
