FRD “Distinct Turbulence Structures in Stably Stratified Boundary Layers with Weak and Strong Surface Shear,” with Dennis Finn…
DetailsHQ Dr. Hyun Cheol Kim is traveling to South Korea August 21-31 for kick-off meetings related to three projects: “Development of top-down emission estimation framework based on artificial intelligence techniques,” “Source Apportionment of PM2.5 using Three-Dimensional Photochemical Models: Top-down adjustment of NOx and SO2 emissions,” and “Development of the Korea-Monitoring Emission Modeling System (K-MEMs).” The…
DetailsHQ From August 6-10, 2018, Xinrong Ren attended the 10th International Conference on Urban Climate/14th Symposium on the Urban Environment held at the City College of New York. He gave a talk titled, “Greenhouse Gas Emissions from New York City Based on Airborne Mass Balance Experiments” and presented some results on aircraft observations from the…
DetailsHQ Student Science and Education Symposium Poster Judging: Alice Crawford and Glenn Rolph served as poster evaluators for the 2018 Student Science and Education Symposium, August 2, 2018, at NOAA Headquarters in Silver Spring, Maryland. Over 100 students participated in this year’s event and provided either oral presentations or a poster for the work that…
DetailsHQ Winston Luke traveled to the Grand Bay National Estuarine Research Reserve (NERR) in Moss Point, Mississippi from July 23-27. The NERR is home to one of ARL’s three sites in the National Atmospheric Deposition Program’s Atmospheric Monitoring Network. This maintenance trip focused on the inspection, calibration, and as-needed repair of the trace gas and…
DetailsHQ WMO RSMC Dispersion Modeling Development: Glenn Rolph has been nominated to lead the effort to complete work on implementing the Transfer Coefficient Matrix (TCM) application developed at ARL for use within the World Meteorological Organization’s (WMO) Emergency Response Activities Program. The TCM application will allow more flexibility by all WMO Regional Specialized Meteorological Centers…
DetailsFRD The manuscript “Distinct Turbulence Structures in Stably Stratified Boundary Layers with Weak and Strong Surface Shear” with Heping Liu from Washington State University as lead author and Dennis Finn as a coauthor received highly favorable reviews in the Journal of Geophysical Research – Atmospheres. It examines turbulent structures and flux exchanges in the stably…
DetailsHQ Long Island Sound Tropospheric Ozone Study (LISTOS): ARL’s air pollutant-measuring equipment, aboard the University of Maryland’s research aircraft, flew over the New York City and Long Island Sound area on July 2 during an episode of the worst air quality in over 10 years, with severe haze and high concentrations of ozone. Measurements taken…
DetailsFRD Roger Carter has been investigating some of the newer halocarbons that are becoming available for their suitability as possible atmospheric tracers. These halocarbons are starting to be used as refrigerants and foam blowing agents, and they have relatively low global warming potentials.Cost, reactivity, and compatibility with existing equipment are some of the factors being…
