Ten years of observations of trace gases at Pico Mountain Observatory (PMO), a free troposphere site in the central North Atlantic, were classified by transport pattern using the Lagrangian particle dispersion model FLEXPART.

The classification enabled identification of trace gas mixing ratios associated with background air and long-range transport of continental emissions, which were defined as chemical signatures. Comparison between the chemical signatures revealed the impacts of natural and anthropogenic sources, as well as chemical and physical processes during long transport, on air composition in the remote North Atlantic.

One million miles from Earth, a NASA camera is capturing unexpected flashes of light reflecting off our planet, and Alex Kostinski has helped identify them as ice particles high in the atmosphere. NASA, Health Medicine Net and Astrobiology Web have published news stories about the phenomena and the research.

Visit here, here and here.

Scientific American and Nature magazine reported on Kostinski’s  research that helped NASA solve the mystery of flashes of light appearing over land, which turned out to be ice crystals high in the atmosphere. See the full story here.

image98360-persHOUGHTON — A Michigan Technological University researcher is leading the effort to create a comprehensive model for the complicated and diverse climate of the Great Lakes region.

Pengfei Xue developed a model combining climate and water models with assistance from Loyola Marymount University, LimnoTech and the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory.

When we have that component, the entire water cycle and surface water cycle would be complete. Then we could estimate the water level change over years.

National Science Foundationby Jenn Donovan

In the National Science Foundation’s (NSF) latest rankings of universities by total research expenditures, Michigan Tech ranked 116th in the nation among public institutions and Tech’s atmospheric science and oceanography research ranked first in Michigan.

Nationally, atmospheric science research at Michigan Tech ranked 39th in research expenditures and oceanography ranked 53rd. Environmental science also ranked 53rd. Tech’s mechanical engineering research ranked 23rd in the nation, the highest ranking of all research fields at the University.

“Michigan Tech has been growing our capabilities in environmental science through our faculty hiring processes like the strategic faculty hiring initiative, our facility development efforts like the Great Lakes Research Center and in our equipment investments such as the cloud chamber in the Earth, Planetary, and Space Sciences Institute,” said Dave Reed, vice president for research. “NSF’s report reflects the impact of those investments and the significant research role that Michigan Tech is playing both nationally and within Michigan.”

The NSF report covered fiscal year 2015.

Other research areas at Tech that ranked in the top 100 nationwide include:

  • Biomedical engineering, 96th
  • Chemical engineering, 98th
  • Civil engineering, 92nd
  • Electrical engineering, 55th
  • Mechanical engineering, 23rd
  • Materials science and engineering, 61st
  • Mathematical sciences, 75th
  • Business and management, 73rd
  • Humanities, 98th
  • Visual and performing arts, 85th

The NSF report showed that research expenditures at Michigan Tech totaled $69.6 million for fiscal year 2015.

The story was shared numerous times by collaborators and the science community on Twitter.

Weather the Storm: Improving Great Lakes Modeling

The collaborative work brought together researchers from Michigan Technological University, Loyola Marymount University, LimnoTech and the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory. Pengfei Xue, an assistant professor of civil and environmental engineering at Michigan Tech, led the study through his work at the Great Lakes Research Center on campus.

One of the important concepts in climate change, in addition to knowing the warming trend, is understanding that extreme events become more severe. That is both a challenge and an important focus in regional climate modeling. —Pengfei Xue

Shaw Wins Research Award

Congratulations to Raymond Shaw (Atmospheric Sciences, Physics) for winning the 2016 Research Award.

In the words of Ravi Pandey, chair of the Department of Physics, Shaw is “widely recognized in the national and international community of atmospheric scientists investigating cloud microphysical processes.”

His research is both detailed and big—from the minutiae of raindrops to understanding the patterns of cloud formation. As part of this research, he collaborates with the National Center for Atmospheric Research (NCAR) to lead a team of scientists to conduct holographic imaging of cloud droplets from an airplane laboratory. The research was published in Science last fall and was the subject of a Michigan Tech Research Magazine story.

“The unifying aspect of my research is the atmosphere,” Shaw says, adding that the process of research inspires him. “It’s like working on an incredibly diverse set of intertwined and nested puzzles. Every now and then a burst of insight allows us to solve a part of one of them.”

Shaw is also recognized for his teaching and says that teaching is another aspect of research. “Students learn at a deeper level when they dig into a research problem,” he explains.

“The advisor-grad student relationship is the closest thing I know to an apprenticeship, where the grad student masters a craft by working side by side with a mentor.”

He considers Alex Kostinski (Physics) his own mentor who has helped him on Michigan Tech’s campus from day one. Along with Pandey’s support and the insight from his students, Shaw says, “Perhaps it sounds quaint, but I do feel like being recognized with the MTU research award is a larger recognition of the colleagues and students with whom I have worked.”
