Background/Education

T. J. Blasing graduated from Arrowhead High School, in Hartland WI, in 1962. He subsequently received undergraduate and graduate degrees from the University of Wisconsin - Madison: Bachelor of Science in Meteorology, 1966; Master of Science in Meteorology, 1968; and Doctor of Philosophy, with a major in meteorology and a minor in statistics, 1975.

He joined the faculty of the College of Geosciences, University of Arizona - Tucson, in September 1971, and he accepted a position on the research staff of the Environmental Sciences Division at Oak Ridge National Laboratory in September 1977. He became an adjunct faculty member in the Geography Department at the University of Tennessee, Knoxville, in 1982 and taught courses there in meteorology and climatology from 1983 to 1998.

His outside interests include soccer, Habitat for Humanity, and world religions. His biographical listings can be found in Who's Who in Technology and American Men and Women of Science.

Research Interests

T. J.'s primary research interest is in air quality, especially the changing concentrations of aerosols and trace gases and consequent effects on climate and the biosphere. (cf. Blasing, 1992). Tracking the sources, sinks, and atmospheric concentrations of certain trace gases (e.g., carbon dioxide, methane, oxides of nitrogen, chlorofluorocarbons, sulfur dioxide, sulfur hexafluoride) can help improve our knowledge of their current and potential future environmental effects; such tracking can also serve to improve our understanding of how various components of our environment function.

A secondary research interest is the characterization of the diurnal behavior of the planetary boundary layer (cf. Blasing et al., 1998). Rapid and predictable changes that occur on large spatial scales are related to pollutant dispersion and transport, as well as to the transfer of energy from small to large scales in the atmosphere - something needing improved representation in general circulation models of climate.

Another interest is synoptic climatology, in which climate and climate change are represented in terms of generalizations about weather events. Recently, T. J. has investigated changes in the annual cycle of climate (cf. Scott et al., 2002). There is increasing evidence that annual changes in the general circulation of the atmosphere that normally occur during the spring are now occurring earlier (Cayan et al., 2001) stimulating earlier occurrences of annual biospheric events such as flowering (IPCC 2001). Transitions from one "natural" season to another often have clear agricultural and/or hydrological consequences. Upsets could occur if, for example, the arrival of corn earworm in Texas (possibly influenced by climate) gets "out of synch" with the breeding cycle of the local bat populations (cf. Bat Patrol, National Geographic Magazine, April 2002).

T.J. is an adjunct professor at the University of Tennessee and has advised or mentored students from several universities throughout the United States. He likes to actively involve students in his research, and student-authored publications frequently result (cf. Scott, et al. 2002; Blasing, Scott and Kaiser, 2003).
