Yatheendradas, Liu’s Assimilation Efficiency article in EOS Research Spotlight
ESSIC Assistant Research Engineer Soni Yatheendradas and ESSIC/CICS-MD Assistant Research Scientist Jicheng Liu recently collaborated on a study titled “The Efficiency of Data Assimilation” published in the EOS Journal Water Resources Research. In the piece, the authors offer a framework to quantify information loss from data assimilation through measuring information in models, observations, and evaluation data. The piece was highlighted in a recent EOS Research Spotlight that details …
Link Between Extreme Rainfall Events and Floods Is Tenuous, Writes Murtugudde
ESSIC/AOSC Professor Raghu Murtugudde recently published an article in The Hindu Business Line titled “Understanding link between extreme rainfall events and floods”. In the piece, Murtugudde writes that contrary to popular belief, there is little connection between extreme rainfall events and rising incidence of floods in India. Instead, factors like soil moisture, thunderstorm size, warm temperatures, water storage capacity of tree canopies, and tree leaf wettability can all affect …
Decline of Arctic Sea Ice Cover Continues, Writes Farrell in NOAA Arctic Report Card
Last December, NOAA released its annual Arctic Report Card, a reflection of the past year’s land, ice, and ocean observations. Sinead Farrell, ESSIC/CICS Associate Research Scientist, co-authored a chapter on Sea Ice alongside international colleagues. The chapter discussed the continuing decline of Arctic sea ice cover. In 2018, the summer maximum extent was the sixth lowest and the winter minimum extent was the second lowest in satellite record. Of particular interest to the …
Farrell Quoted on Synthetic Aperture Radar in Nature
ESSIC / CICS-MD Associate Research Scientist Sinead Farrell was quoted in a recent article published in Nature titled “Arctic scientists iced out by US–India radar mission”. The story discusses NISAR, an upcoming NASA and Indian Space Research Organisation (ISRO) radar mission that will study changing polar ice. Recently, NISAR mission managers have made the decision to focus the satellite’s observations on Antarctica, removing the possibility of monitoring Arctic sea ice …
Farquhar Develops Method to Analyze History of Climate-Altering Volcano Eruptions
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 …
ESSIC/CICS Scientists Present at AGU & AMS Annual Conferences
ESSIC / CICS-MD scientists actively participated in two recently convened annual societal meetings. The week-long American Geophysical Union’s (AGU) Fall Meeting (AGU) held during early December 2018 in Washington, D.C., boasted 1,900 oral and poster sessions, 26,000 abstracts, and 24,000 attendees. A number of ESSIC/CICS scientists presented talks, including Melissa Kenney, Ross Salawitch, and Dorothy Hall. (A listing of some of the ESSIC / CICS affiliated participants can be found …
Mishonov and Reagan Published on The Northwest Atlantic Regional Ocean Climatology
In collaboration with NOAA colleagues Dr. Dan Seidov, Dr. Rost Parsons, and others, ESSIC Associate Research Scientist Dr. Alexey Mishonov and ESSIC / CICS-MD Senior Faculty Specialist James Reagan recently published an article titled, “Regional Climatology of the Northwest Atlantic Ocean: High-Resolution Mapping of Ocean Structure and Change” in the Bulletin of the American Meteorological Society. The article discusses the Northwest Atlantic Regional Ocean Climatology, a recent …
Zheng Co-Authors Article in Science on Aerosol Cooling Effect on Marine Clouds
ESSIC / CICS-MD Post-doctoral associate Youtong Zheng recently co-authored a paper published in Science titled, “Aerosol-driven droplet concentrations dominate coverage and water of oceanic low level clouds”. The article introduces a methodology for ascribing cloud properties to cloud condensation nuclei (CCN) and isolating aerosol effects from meteorological effects. This new finding is largely based on a series of novel satellite remote sensing techniques of estimating the vertical …
Li Gives Keynote Presentation at AMS
Zhanqing Li, AOSC/ESSIC Professor, recently gave a Core Science Keynote Presentation at last week’s AMS Annual Conference. The presentation, titled “Can air pollution fuel extreme weather events and contribute to long-term climate changes”, discusses the major impact that aerosols can have on extreme weather events such as heavy rainfall, thunderstorms, and lightning over densely populated regions. Despite the government shutdown that impacted the conference’s overall attendance, the …
