R. Chatfield presents ozone research at AGU

Robert Chatfield (SGG) made a presentation at the American Geophysical Union, held Dec. 11-15, 2006, in San Francisco. concerned with air pollution, from urban to regional scales. His talk, "POGO-FAN: Remarkable Empirical Indicators for the Local Chemical Production of Smog, Ozone and the NOx-sensitivity of Air Parcels," was delivered during a special session concerned with air pollution, from urban to regional scales.

The acronym “POGO-FAN” stands for Production of Ozone by the Gauging of Organic oxidation -- Formaldehyde and Nitric Oxide. The technique could be rigorously tested for all the pollutant situations of the Eastern and Central U.S. by the wide-ranging DC-8 aircraft that flew in NASA's INTEX-NA mission. The high technology sensing aboard the aircraft demonstrated the quality of a modest-cost technology involving only a few, relatively inexpensive instruments.

The technique also emphasizes the potential for NASA satellite observations in determining ozone production and concentrations. This addresses national needs as many local regions are affected by upwind areas. Additionally, the technique can spotlight the often-small effect of local emissions, or suggest local unsuspected difficulties. Measurements of formaldehyde, nitrogen dioxide, and ultraviolet-light exposure from space appear extremely useful.



F. Freund gives radio interview on earthquake prediction research

Friedemann Freund (SJSU/SGE) was interviewed, Jan. 2, by radio host Mitch Battros for the show, “Earth Change,” a biweekly program broadcasting from Seattle, Washington. The topic for discussion was Freud's research into pre-earthquake signals and the number of strong or subtle interactions that have been seen between the sun/ionosphere system and solid Earth/earthquake triggering.



Biospheric Science team attend ESIP meeting

Vince Ambrosia (CSUMB/SGE) and Don Sullivan (SGE) participated in the Earth Science Information Partnership (ESIP) meeting in Portland, Oregon, during the week of January 2-5. Ambrosia and Sullivan led efforts on the development of the Disaster Management Cluster Focus Group of the ESIP Federation, and detailed their work in Disaster Management, Information Sharing, and the collaborative efforts with GoogleEarth as an information-visualization tool. Ambrosia and Sullivan also had informal meetings with Karen Moe, of NASA Earth Science Technology Office (ESTO) during the ESIP Federation meeting. (POC: V. Ambrosia, 4-6565, vambrosia@mail.arc.nasa.gov)
