In 1986, chlorofluorocarbons (CFCs), chemical compounds known to break down ozone in the atmosphere, were banned by the Montreal Protocol. This led to an immediate rapid decline in emissions. However, recent studies have shown that CFC-11 emissions have increased, suggesting a contribution from eastern Asia.
On August 18, 2021, the western part of North Carolina suffered a catastrophic flash flood caused by Tropical Storm Fred. As part of a NOAA/STAR precipitation validation project, CISESS science team Malar Arulraj, Veljko Petković, Ralph Ferraro, and Huan Meng evaluated the performance of different satellite-based precipitation products during this event using Multi-Radar/Multi-Sensor (MRMS) observations.
ESSIC/CISESS scientist Sinéad Farrell is one of the contributors to the new “State of the Climate in 2020: The Arctic”, released by the American Meteorological Society (AMS) in the August 2021 issue of the monthly bulletin (BAMS). She co-authored the section on sea ice extent.
This week, ESSIC/CISESS Scientists Joseph Patton and Guangyang Fang and Summer Intern Terrence Pierce visited one of our lightning detection stations on the campus of Howard University-Beltsville. The GPS antenna for the station had been giving them trouble, so they installed new connectors for the cable that connects the GPS antenna to the lightning detection computer, and that seems to have resolved the problem.
ESSIC/CISESS Visiting Research Scientist Tom Smith is coauthor of an article on DOISST v.2.1 coming out in the September 2021 issue of the Journal of Climate. The paper, titled “Assessment and Intercomparison of NOAA Daily Optimum Interpolation Sea Surface Temperature (DOISST) Version 2.1”, shows how the improved NOAA operational analysis compares to several other available analyses.
ESSIC/CISESS Scientists Yalei You, John Xun Yang, and Jun Dong have a new article on using “morphing” to improve rain data from cross-track scanning radiometers. The paper, titled “Improving Cross-track Scanning Radiometers’ Precipitation Retrieval over Ocean by Morphing”, is in press at the Journal of Hydrometeorology.
ESSIC/CISESS Scientists John Xun Yang and Hu Yang have a new article in press at IEEE Transactions on Geoscience and Remote Sensing titled “A New Algorithm for Determining the Noise Equivalent Delta Temperature of In-Orbit Microwave Radiometers”.
Congratulations to Xin-Zhong Liang, newly elected Fellow of the American Meteorological Society (AMS). This honor is an apt recognition of his vigorous multidisciplinary research efforts and notable achievements.
Joe Munchak, the NASA GPM Deputy Project Scientist for Ground Validation (GV), will be leaving NASA at the end of this week to pursue a career in the private sector. Muncak has served in this role since 2010, when he left ESSIC. Dave Wolff will be filling Munchak’s position at NASA, after being with Goddard since 1988.
ESSIC/CISESS Scientists Xin Jing, Xi Shao, Tung-Chang Liu and Bin Zhang (STAR/SOCD) have a new article in the July 2021 issue of Atmosphere titled “Comparison of GRUAN RS92 and RS41 Radiosonde Temperature Biases”.
