The OMI NO2 group produces the Ozone Monitoring Instrument (OMI) standard nitrogen dioxide data product, supports measurement validation studies, and conducts research and development toward algorithm improvement. We also use the nitrogen dioxide data for scientific studies, and support its use by others in the science community.
Edward Celarier received B.S. degrees in chemistry and physics/astronomy (1981) from the University of Washington, in Seattle, and a Ph.D. in physical chemistry (1986) from the University of Toronto. He was a postdoctoral fellow at Princeton University (1986-1989). After that, he joined the chemistry faculty of Hampton University (Hampton, VA). In 1995, he began work with the Atmospheric Chemistry and Dynamics branch (now Code 613.3) at NASA Goddard Space Flight Center, working for Software Corporation of America, Hughes STX, and Stinger Ghafarian Technologies, Inc. In February 2008, he was hired as Associate Research Scientist by UMBC/GEST; in 2011, he joined GESTAR. During his 15-year association with NASA, Dr. Celarier has worked in the area of measuring trace gases in the Earth's atmosphere using satellites and using ground-based instruments, particularly the measurement of ozone (O3) and nitrogen dioxide (NO2), using the TOMS instruments (O3) and the Ozone Monitoring Instrument (OMI) on NASA's EOS-Aura satellite (NO2). Dr. Celarier has also been responsible for the development and implementation of algorithms that produce publicly distributed data sets, including OMI NO2 and the Surface Ultraviolet Exposure data set produced from TOMS data; the latter algorithm has also been implemented by the Finnish Meteorological Institute to produce a Surface Ultraviolet Exposure data product from OMI. He is also responsible for an Earth surface ultraviolet reflectivity climatology data set, based on TOMS data, that is widely used for other trace gas retrieval algorithms. Finally, he has worked in the area of validation of satellite-based measurements of atmospheric trace gases and ultraviolet exposures, using ground-based measurements. In addition to his research work, Dr. Celarier has taught students from 3rd grade to university, as an assistant professor of chemistry at Hampton University, as a volunteer teacher for 4-H's Adventure in Science Program, supported by the National Institutes of Standards & Technology (NIST), and for workshops run by Dr. Dianne Robinson at Hampton University. He has also taught computer skills to high school students and clerical workers. Dr. Celarier has devised numerous hands-on science activities for students, and some of the students who have participated have gone on to develop some of these activities into science fair projects. At Hampton University, he revised the suite of experiments for the physical chemistry laboratory course, redesigning several experiments and introducing some novel ones. Dr. Celarier was a coauthor of a NASA-produced online textbook on stratospheric ozone. Dr. Celarier has recently been involved in educational projects for high school and university students at the Instituto TechnolÃ³gico de Monterrey Campus Guadalajara, focused on understanding the atmosphere and global warming and climate change.
