ARL and the National Atmospheric Deposition Program provide data for important research

A paper was recently published in Environmental Research Letters about National Atmospheric Deposition Program (NADP) data used to document the effects of the East Palestine, OH train derailment on February 3, 2023. The paper highlights the importance of measuring wet-deposited contaminants. Data for this analysis were taken from the NADP National Trends Network; ARL funds and operates six sites in the network and the analysis used data from three of those sites in PA, NY, and MD. The paper also used ARL’s HYSPLIT to compute forward trajectories. 

GMU Cooperative Institute Team Hosted a Workshop

Our Cooperative Institute team in George Mason University (GMU) successfully hosted the 2nd Annual, Greater Washington D.C. Air Quality Research and Development Consortium (AIRDC) Workshop in Fairfax, VA on July 17.

More than 20 atmospheric Composition researchers from GMU, UMD, UMBC, JHU, JWU, Howard University, NOAA, DOE and NASA in the DC area as well as some scientists from Boulder, CO, attended this workshop. They discussed topics from air pollution emissions, air quality modeling, data assimilation/fusion to satellite data applications. They shared recent research and plans and agree that a further collaboration will be beneficial to this community. The next AIRDC will be hosted by JHU (John Hopkins University) in 2025.  

Community Outreach

On June 18, Temple Lee, Kurt Daniels, Randy White, and Dominick Christensen demonstrated a weather balloon launch for about 90 students, ranging from kindergarten through eighth grade, at White Pine School in White Pine, TN. Temple and the group discussed the importance of measurements obtained via weather balloons and answered students’ questions about the weather.

Many thanks once again to Kurt, Randy, and Dominick for their hard work, as well as their preparation for the event!
