Earth's climate system is characterized by complicated and fascinating interactions between physical, chemical, and biological processes. My current research ambitions lie in understanding processes that govern cryosphere-climate interaction and feedback. These processes range from the physics of snow melt, to atmospheric transport and processing of aerosols, large-scale energy transport, snow-vegetation interaction, and radiative transfer in the atmosphere and cryosphere. I strive to study these interactions using a combination of numerical modeling, remote sensing observations, and experimental studies.
Students interested in researching these and related topics are welcome to contact me about potential graduate studies.
January, 2013 — Mark is one of 31 co-authors of a 4-year international study bounding the role of black carbon in climate. The study, published in JGR, concludes that black carbon exerts a substantially stronger warming effect on climate than quantified in the IPCC (2007) report. Media coverage:
June, 2012 — Mark lectures on aerosol-cryosphere-climate interactions at the Alpine Summer School in Valsavarenche, Italy. Lecture slides are available through the website.
June, 2012 — Alex accepts a professorship in the Geography Department at Clark University, starting September 2012.
February 16, 2012 — On invitation from Secretary of State Hillary Clinton, Mark visits the State Department to attend the announcement of a new U.S.-led Initiative on Climate Change and Clean Air, targeted at reducing short-lived pollutants that adversely affect both climate and health.
