Jeep Accident, Sea Ice Anomalies and Global Warming


Growing up in a religious town in northern Philippines, Dr. Josefino "Joey" Comiso's early involvement in science was relatively modest, but a jeep accident and the advent of the jet era changed his career path. He did a few years of particle physics research before joining the cryosphere group at NASA/GLAS and got involved in the analysis of satellite data, field programs and process studies that led to many breakthroughs in our understanding of the role of sea ice and the polar regions in our climate system. In his Maniac Talk on Nov 5th, he also discussses his recent experiences as a coordinating lead author in the upcoming IPCC/WG1/AR5 report and the educational outreach he has been doing in the Philippines.

My Radiative Transfer Journey: from Pure Math to Aerosols and Clouds with Stops at Nuclear Reactors, Vegetation & Fractals


Dr. Alexander Marshak came to GSFC as a radiative transfer scientist in 1991 following a lengthy journey through many aspects of transport theory: he started with math at Tartu (Estonia) then learned about nuclear reactors in Novosibirsk (Russia), vegetation back in Tartu and Goettingen (Germany), and finally atmosphere at Goddard. In the talk, as he goes through the journey, he focuses on the specifics of atmospheric radiative transfer compared to other radiation fields and how studies in these fields can help to better interpret remote sensing observations of aerosols and clouds.
