Xu, Wang, and Chen study published in IEEE journal

August 24, 2018

ESSIC / CICS-MD scientists Hui Xu, Likun Wang, and Yong Chen (STAR/SMCD) have an article in press at the IEEE Transactions on Geoscience and Remote Sensing titled “Cross-Track Infrared Sounder Spectral Gap Filling Toward Improving Intercalibration Uncertainties”. The paper focuses on the Joint Polar Satellite System (JPSS) Cross-Track Infrared Sounder (CrIS), a hyper-spectral infrared sounder used to check calibration accuracy of narrow or broadband instruments. Despite the sounder’s …

Li Awarded Department of Energy Grant For Study Into Aerosol-Cloud Interaction

August 3, 2018

In June, the U.S. Department of Energy (DOE) announced $15 million in funding for 27 projects in atmospheric and ecological sciences in an effort to improve Earth systems models and better predict weather and climate. One of these projects includes AOSC-ESSIC professor Zhanqing Li’s research, “Investigation of the surface coupling of marine clouds and its interactions with aerosols over the Southern Ocean”. The grant will utilize Atmospheric Radiation Measurement (ARM) data (from the …

ESSIC participates in 20th Maryland Day

May 3, 2018

A sunny Maryland Day made for the perfect opportunity for ESSIC staff to engage with Terps of all ages about Earth sciences. ESSIC assistant research scientist Michael Peterson organized a virtual reality activity with severe weather visuals. Visitors could view imagery from the NOAA GOES-16 satellite, including Hurricane Harvey, thunderstorms in Argentina and Brazil and the lightning hotspot over Venezuela’s Lake Maracaibo. There were also lighting visuals, including two that …

Chen publishes article on Cross-Track Infrared Sounder algorithm

March 22, 2018

ESSIC associate research scientist Yong Chen published a new article in the February issue of IEEE Transactions on Geoscience and Remote Sensing titled “Calibration Algorithm for Cross-Track Infrared Sounder Full Spectral Resolution Measurements.” Chen leads a CICS task on calibration and validation of the Cross-Track Infrared Sounder (CrIS) on the Suomi NPP and new JPSS-1/NOAA-20 satellite. The article documents a new calibration algorithm for the CrlS….

ESSIC’s Holm ensures smooth sailing for Center travelers

February 28, 2018

Between conferences, workshops and field research, you could conceivably find one of ESSIC’s 160 scientists in any corner of the world on a given day. Cathy Holm has been making sure those adventures run smoothly for nearly six years. Holm, a travel and procurement specialist with the ESSIC Business Office (EBO) manages researchers’ trips, which can often require specialized equipment and medical clearances given how remote and rugged the destinations can be. …

Li and Zhang publish in Science

January 31, 2018

ESSIC / AOSC professor Zhanqing Li and AOSC graduate student Yuwei Zhang are co-authors of a paper published in Science titled “Substantial convection and precipitation enhancements by ultrafine aerosol particles.” It reports that miniscule aerosol particles can influence weather more dramatically than previously thought, including storm and rain intensity. Read a press release here….

Li publishes study on aerosol indirect effect in China

January 24, 2018

ESSIC / AOSC Professor Zhanqing Li is a co-author of a new study published in Advances in Atmospheric Sciences titled “First surface-based estimation of the aerosol indirect effect (AIE) over a site in southeastern China.” According to Li, the use of ground-based measurements is one of the most important methodologies for both quantifying the magnitude of AIE and understanding the underlying mechanisms. The authors were the first researchers to utilize the approach in China. …

September 5, 2017

ESSIC Assistant Research Scientist Lauren Zamora presented a recent webinar entitled, "Quantifying aerosol indirect effects over the Arctic" at the IARPC (Interagency Arctic Research Policy Committee) Atmosphere Collaboration Team meeting. The presentation can be viewed at the following link. …

Zamora a co-author of recent study

July 25, 2017

ESSIC Assistant Research Scientist Lauren Zamora is a co-author of a recently published study in the European Geosciences Union journal Atmospheric Chemistry and Physics. The paper titled “Observation- and model-based estimates of particulate dry nitrogen deposition to the oceans,” concludes that current computer models are vital in assessing ocean nitrogen deposition—a nearly impossible task through direct monitoring–and should be developed further to better …
