Yearlong study to examine atmospheric conditions over Baltimore

A climate study focusing on the atmosphere above Baltimore is in the works for next year.

A team of 23 investigators from 13 research institutions will deploy field equipment on loan from the U.S. Department of Energy. The project is called the Coast-Urban-Rural Atmospheric Gradient Experiment and will examine interactions between the surface and atmospheric boundary layer to see how it impacts the city's climate.

The Department of Energy made one of its multi-instrument Atmospheric Radiation Measurement mobile units available to researchers.

Ken Davis, professor of atmospheric and climate science at the Pennsylvania State University and the project lead, said the measurement system enables scientists to study several things at once.

"It's a bit unique in that they have all of these different types of measurement systems together and that's the purpose," Davis explained. "Because the clouds influence the radiation, which influences the precipitation, which influences the climate, and measuring them all together lets you look at all these different aspects of the system, which is very powerful."

The project was announced recently, and Davis pointed out the instruments will be deployed for a year, likely beginning around December 2024.

While the main ARM unit will be located at Morgan State University's Clifton Park site, two smaller observational nodes will be deployed outside the city. One will be in a rural site northwest of Baltimore, and the other on an island in the Chesapeake Bay.

Davis noted studying the atmospheric conditions at each location will help scientists understand how the region's climate is impacted by these different environments.

"One way I like to explain this is we will make many measurements through the long-term study of the city of Baltimore. But I say what about the neighbors? There are neighboring environments that influence the city," Davis outlined. "This ARM deployment will help us to expand our reach beyond just the city of Baltimore, to the surrounding environment."

Researchers believe by studying the interaction between coastal, urban and rural environments, they can improve future climate models. Davis added it will help Baltimore and similar cities plan more effective climate adaptation and mitigation efforts.
