UMBC, NASA, and Partners Mount Intensive Chesapeake Bay Air-Quality Study

SCIENCE & TECHNOLOGY AUGUST 21, 2018 10:26 AM SARAH HANSEN

Dr. Ruben Delgado Research Scientist with UMBC JCET Department

This Summer, students and faculty from UMBC and three additional universities teamed up with NASA researchers and Maryland’s Department of the Environment to collect huge amounts of data that will provide a snapshot of air quality in the Baltimore-Washington metropolitan area and over the Chesapeake Bay. The study measures factors ranging from wind speed to ozone concentration.

“In trying to understand air quality near the coast, it’s critical to obtain measurements over the water and over the land simultaneously with as wide of a variety of instruments as possible,” says John Sullivan, Ph.D. ’15, atmospheric physics, and the lead NASA researcher on the project.

UMBC serves as the primary land-based site, and equipment placed on remote Hart Miller Island in the Bay collects data over water. “With two sites, you can begin to really answer questions pertaining to differences in air pollution and understand the mechanisms driving these differences,” Sullivan explains.

Ozone in the forecast

This summer’s work is an extension of the Ozone Water-Land Environmental Transition Study (OWLETS), dubbed OWLETS-2, and it is particularly focused on tracking the presence of ozone in coastal cities. Ozone in the upper atmosphere helps maintain Earth’s temperature and absorbs harmful UV rays.

However, near ground level, breathing in ozone causes inflammation in the respiratory system, which can be dangerous for young children, the elderly, and those with asthma or other respiratory conditions. Plants also take up ozone, which can reduce crop yields.

Chemical reactions between sunlight and emissions from vehicles and industry generate smog-like ozone episodes, so one would expect the highest concentrations at midday, when the sun is at its brightest. However, wind over the Bay changes that.

“The Bay breeze is like a wall that doesn’t allow normal west to east airflow to happen,” explains Ruben Delgado, assistant professor at the Joint Center for Earth Systems Technology (a UMBC-NASA partnership) and the lead UMBC OWLETS-2 researcher. That means the midday ozone heading out to sea comes back in during the late afternoon, causing a spike just as local residents are heading home from work and school. Other factors, such as smoke blowing over the city from wildfires in the West, can also have a real impact.

Better understanding how these issues influence the presence of ozone in Baltimore can help improve air quality forecasts and protect sensitive populations from ozone’s ill effects. “The National Weather Service is interested in this kind of data, because it allows them to push their models to a new frontier,” Delgado explains.

Students step up

Working with Delgado are students from UMBC, Howard University, City University of New York, and Hampton University. The students and their home-institution faculty mentors are all members of the NOAA-funded Center for Earth System Sciences and Remote Sensing Technologies and Center for Atmospheric Sciences and Meteorology.

Delgado finds mentoring these emerging researchers to be both personally rewarding and essential to the success of the project. “My favorite part of this project is giving the students hands-on experience,” Delgado says. “They get to contribute to the process from start to finish.”

Kat Ball ’21, chemical engineering, is one of those student researchers, and her experience has been transformative. “I feel so fortunate to have had the opportunity to participate in meaningful scientific research so early on in my academic career,” she shares. “I’ve only just completed my freshman year, and will be one of the authors on the publications that result from all the data we received, which is something I thought I would only be dreaming about for quite some time.”

Ball learned that field and lab research differ in important ways. “Not everything is easy to deal with when you’re miles away from an actual lab where you have all of the necessary parts, chemicals, and even just clean water that you need to deal with problems that arise,” she says.

Working with much more experienced team members, Ball was intimidated at first, but soon felt at home on Hart Miller Island. “Hearing from people with such impressive qualifications that your input on the situation truly matters expanded the confidence I had in myself as a researcher,” she shares.

 Air Quality Study Over Chesapeake Bay Seeks To Understand Pollution

Article by Liz Bowie – Contact Reporter for Baltimore Sun

The sky above Hart-Miller Island became a busy laboratory for several weeks this summer as researchers launched balloons, drones and planes to better understand the complex swirl of air pollution over the Chesapeake Bay.  State and federal agencies initiated a research study aimed at providing more detailed data on how and why the Chesapeake Bay seems to act as a magnet for ozone pollution, amplifying the smog before it is then blown back over land.  “The study is an exciting example of cutting-edge research on the interface between land and water,” said Maryland Environment Secretary Ben Grumbles.  The study attempts to understand in a three-dimensional way what happens to the emissions of power plants, cars and other pollutants once they gather over the Chesapeake Bay. The results could help Maryland make the case for forcing sources of air pollution in states upwind to better control their emissions.  Maryland officials blame air pollution from upwind states for more than two-thirds of the smog that forms over the Baltimore and Washington regions. On hot summer days, the sunlight and heat trigger chemical reactions between pollutants and other compounds in the air, multiplying what is known as ground-level ozone.  Ozone is a form of oxygen found naturally in the upper atmosphere that protects the Earth from ultraviolet radiation, but ground-level ozone is a key ingredient in smog and can cause or aggravate breathing or heart problems in humans.  Already this year there have been eight days when Baltimore’s air quality exceeded U.S. Environmental Protection Agency standards.  Ozone is created by the chemical reactions between pollutants known as nitrogen oxides and volatile organic compounds. Nitrogen oxides come from the combustion of fossil fuels in cars and power plants. The nitrogen often falls out of the air as ozone is created.  About a third of the bay’s nitrogen pollution falls from the air onto the land and water, said Ariel Solaski, a staff litigation attorney at the Chesapeake Bay Foundation. Excess nitrogen in the bay contributes to algae blooms and dead zones.  Significant improvements in the bay’s water quality have been seen since nutrients including nitrogen have been reduced in the rivers and streams flowing into the bay.

UMBC Atmospheric Scientists Use New Instrumentation

To Study Cloud and Aerosols in Exploratory NASA Aircraft Campaigns

Aerosol-cloud interaction continues to puzzle climate scientists. It is among the most significant contributors to our climate but least understood. Aerosol-cloud processes are poorly represented in climate models and measurement requires high accuracy, narrow resolution, and cooperation between different instruments.

Several studies converge on the idea that a multi-angle imaging polarimeter, with high accuracy and narrow spatial and angular resolution, is the strongest candidate to sample cloud and aerosol properties at the level required for climate study. The Hyper-Angular Rainbow Polarimeter (HARP) is a wide field-of-view camera, designed and developed by J. Vanderlei Martins and the Laboratory for Aerosol and Cloud Optics (LACO) Group at UMBC to fill this role.

Over the past year, AirHARP, the HARP instrument adapted for aircraft, flew on two NASA research campaigns: the Lake Michigan Ozone Study (LMOS) and the Aerosol Characterization from Polarimeter and LIDAR (ACEPOL). The LMOS campaign was a joint NASA-NOAA-EPA effort to explore the connection between lake breezes and high ozone exceedance levels on the eastern coastline of Wisconsin in the summer months. AirHARP took data on many B-200 flights alongside the NASA Langley Research Center (LaRC) GeoTASO instrument, a trace gas experiment that measures ozone pre-cursors, such as NO₂, through the entire atmospheric column. Brent McBride, a Ph.D candidate in Martins’ group, operated AirHARP on-board the B-200 and led field operations on the ground throughout the campaign, while LACO group members engaged remotely from UMBC. While AirHARP does not have trace gas sensitivity, measurements of convective clouds and low aerosol levels over eastern Wisconsin will be compared to co-incident observations made by AERONET sun photometer sites and the Advanced Baseline Imager (ABI) on the GOES-R geosynchronous satellite.

UMBC Physicists Discover Unexpected Effect of African

Wildfires on Climate

African Fires Effect Climate

Clouds play a prominent role in moderating Earth’s climate, but their role is still poorly understood. Generally, clouds cool the Earth by reflecting incoming sunlight back out into space. Reducing the clouds’ reflectivity—with a layer of pollution, for example—reduces the cooling effect. However, new research in Proceedings of the National Academy of Sciences by Zhibo Zhang, associate professor of atmospheric physics at UMBC, two of his students, and collaborators from University of Wyoming, University of Science and Technology of China, Universities Space Research Association, and University of Michigan adds another level of complexity to this model.

Every fall, fires race across central and southern Africa. Many are wildfires; others are intentionally set by humans to clear farmland. They create so much smoke that it’s clearly visible from space. Wind sweeps the smoke westward over the Atlantic Ocean, where it rises above the largest semi-permanent gathering of clouds in the world. For years, scientists believed that overall, the smoke diminishes the clouds’ cooling effect by absorbing light that the clouds beneath otherwise would reflect. The new study by Zhang and colleagues doesn’t dispute the existence of this effect, but introduces a new mechanism that counteracts it by making the clouds more reflective.
