Dr. Henry B. Selkirk received his Ph. D. in Meteorology in 1986 from the Massachusetts Institute of Technology (MIT), Cambridge, MA and a BA in 1977 from The Evergreen State College in Olympia, WA. His Ph.D. thesis was an observational study of the Madden-Julian oscillation. Before joining GESTAR in May 2011, Dr. Selkirk worked at GEST/UMBC for three years, and had been working in the Earth Sciences Division at NASA Ames Research Center on topics related to tropical climate, weather and wave dynamics, atmospheric trace constituents, aerosols and transport processes, and stratosphere-troposphere exchange processes. He has participated in some 20 research aircraft missions since 1987 providing flight planning and meteorological support. In 2004 he organized with Costa Rican collaborators the first of what became five Ticosonde high-frequency radiosonde campaigns in Costa Rica, extending these observations in 2005 to what is now an ongoing program of CFH and ECC ozonesonde measurements. This continuing work remains a joint enterprise with Dr. Holger Vömel of the National Center for Atmospheric Research, Dr. Jorge Andrés Diaz of the Universidad de Costa Rica, and Dr. Anne M. Thompson of NASA Goddard Space Flight Center. Ticosonde observations continue to provide a unique and important source of accurate water vapor measurements in the TTL for satellite validation and climate modeling. In 2012, Dr. Gary Morris, now at St. Edwards University, brought to the team his expertise in the measurement of SO2 using a dual ozonesonde system and measurements of SO2 emissions from nearby Turrialba volcano are providing a valuable source of validation for satellite-based SO2 column measurements.
