ESSIC / Geology Professor James Farquhar recently co-authored a new paper, “2600 years of stratospheric volcanism through sulfate isotopes,” in Nature Communications.  Using 2,600 years’ worth of records contained in ice cores from Antarctica, Farquhar and his colleagues developed a new isotopic method to analyze the recent history of large stratospheric volcanic eruptions. By understanding the history of these big eruptions, researchers can begin to place short cooling episodes and …

A paper co-authored by ESSIC-AOSC professor Raghu Murtugudde was recently published in the July 2018 edition of Nature Sustainability.  The piece, titled “Bridging barriers to advance global sustainability”, is a discussion about how academic institutions can better support society’s efforts towards global sustainability.  The authors call for new structures of fostering knowledge that are integrated across disciplines and produced alongside non-academic stakeholders.  The article …

An article by ESSIC/CICS-MD post-doctoral associate Xiaoxu Tian and by ESSIC/CICS-MD research professor Xiaolei Zou was recently accepted for publication in the American Meteorological Society’s Journal of Atmospheric Sciences. The piece, titled “Capturing Size and Intensity Changes of Hurricanes Irma and Maria (2017) from Polar-Orbiting Satellite Microwave Radiometers”, is an analysis into the temporal evolutions of the three-dimensional thermal structures of Hurricanes Harvey, Irma, and …

ESSIC post-doctoral associate Michael Peterson developed a virtual reality visualization of Hurricane Harvey using GOES-16 which puts the viewer on the space station looking down at the hurricane. Viewers can move their mobile phones in different directions for different views of the storm or use virtual reality equipment to immerse themselves in the visuals. You can view the animation here.  …

ESSIC / GEOL Professor James Farquhar is a co-author of a newly released study published in the online edition of the Proceedings of the National Academy of Sciences. The paper entitled “Biological regulation of atmospheric chemistry en route to planetary oxygenation,” explores emerging evidence that a methane-derived organic haze was a large contributing factor associated with the Great Oxidation Event.  During the global scale phenomena that occurred over 2 billion years …

A new study from scientists Jungbin Mok and Zhanqing Li, Earth System Science Interdisciplinary Center (ESSIC) University of Maryland, and Nickolay Krotkov, NASA Goddard Space Flight Center, is focusing on the impacts of brown carbon from biomass burning on ultraviolet (UV) radiation and atmospheric pollutants, which could lead to improved air quality models and help ameliorate potential health hazards such as suppression of the immune system and skin cancer. The paper is being released in

Work by Anand Ramanathan and Jianping Mao of ESSIC as part of the NASA Goddard CO2 Sounder lidar instrument team was presented at the 12th International Workshop for Greenhouse Gas Measurements from Space (IWGGMS), held in Kyoto, Japan from June 7-9. Highlights including results from the recent NASA ASCENDS airborne campaign in California and Nevada which showed 3x higher precision in column CO2 measurements, simultaneous column water vapor measurements, and the …
