ARL/NIST Greenhouse Gas Measurement Collaboration

In collaboration with Dr. Anna Karion at the National Institute of Standards and Technology (NIST), Phil Stratton and Xinrong Ren visited a greenhouse gas measurement lab at NIST on March 2, 2022 to calibrate a Picarro carbon dioxide and methane analyzer and a few greenhouse gas reference cylinders to get ready for the planned street-level mobile measurements of greenhouse gases and air pollutants in the Baltimore-Washington area. During the visit, Phil and Xinrong discussed with Dr. Karion about the deployment of a NIST ethane analyzer during the mobile measurements. The combination of methane and ethane detection can be used to identify methane emissions from pipeline gas to be distinguished from biogenic sources. They also discussed the survey of several greenhouse gases sources in the area and the coordination between the mobile measurements and the NIST-funded tall tower measurements of greenhouse gases in the Northeast Corridor.

New ARL sUxS Mission Commander

On 2 March, Temple Lee successfully completed the flight readiness review with the UxS UAS Division Aircraft Operations Center. Doing so allowed him to become the new mission commander for ATDD’s uncrewed aircraft system (UxS) operations and enabled ATDD to resume its UxS operations to study land-atmosphere interactions and boundary layer processes. The mission commander position was formerly held by Bruce Baker until his retirement in December 2021.

Papers Sought on Improving Air Quality Predictions and Assessment Across Scales
ARL’s Dr. Patrick Campbell and Dr. Barry Baker along with EPA’s Dr. Daiwen Kang are guest editors on the release of a Special Issue, “Improving Air Quality Predictions and Assessment Across Scales” in the journal Atmosphere. This special issue invites the submission of research papers that investigate improved methods, applications, and evaluations of air quality assessments and predictions across scales. The deadline for paper submission is September 30, 2022.  More information on the special issue, including how to submit your research paper(s) may be found at this link.
