ARL Hosts Combined Atmospheric Sciences Meeting

May 2019

ARL hosted the second annual Ozone Water Land Environmental Transition Study (OWLETS) and sixth annual Tropospheric Ozone Lidar Network (TOLNet) Science Team Meetings in College Park, Maryland, from May 6-8, 2019. Over 50 scientists participated in the joint event, representing NOAA, NASA, and EPA, as well as multiple universities and state agencies involved in air quality monitoring.

Acting Deputy Director Dr. Ariel Stein gave opening remarks and seven other ARL staff members delivered and/or contributed to presentations. Barry Baker presented on data visualization using ARL’s Model and Observation Evaluation Toolkit (MONET), a resource that is applicable to both OWLETS and TOLNet; Winston Luke and Paul Kelley contributed to a presentation on analyses of ARL’s Hart Miller Island Observations; Christopher Loughner presented on ARL’s Weather Research and Forecasting (WRF) modeling work related to OWLETS; Pius Lee contributed to the NAQFC Program Manager’s presentation on synergy between NOAA offices working on OWLETS and future collaborations; Xinrong Ren presented on his air quality monitoring efforts with the University of Maryland and its Cessna aircraft; and Howard Diamond presented an overview of ARL and its relationship to the OWLETS effort.


OWLETS, a study to better identify and characterize the coastal interactions of ozone within the Chesapeake Bay, took place in 2017 and 2018. Vertical profile measurements over land and water were complemented by remote sensing and in-site observations of air quality from ground-based, airborne, and shipborne platforms. These observations were then coupled with chemical transport simulations from NOAA’s National Air Quality Forecast Capability (NAQFC) model. Scientists are working toward a more fully-characterized and complete land-water interaction observing system for use in assessing future geostationary air quality instruments and current low earth orbiting satellites.

About TOLNet

Formed in 2011, TOLNet is a collaborative group of researchers within NASA and NOAA dedicated to providing the larger atmospheric community with ozone profiles that can be used for applications such as model/forecast evaluation and process studies.
