Air Pollution in North Portland: Results as of April 2016 by Ted Eckmann, Assistant Professor of Environmental Studies University of Portland, eckmann@up.edu We made observations for over a year, collecting over 23,000 data points from 19 stations, observing three times daily at each station. Houck et al. (2015) and Oliver & Webster (1990) describe our methods. Fraction of days with detected industrial odor: December 2014 to February 2015, 6am to 8am Local Time: Fraction of days with noticeable industrial odor, modeled using ordinary Kriging Dots show locations of the 19 stations used to produce the interpolated map above; standard error is below. Units for both are fraction of days with detected industrial odor. Maps from Wright et al. (2016) December 2014 to February 2015, 6am to 8am Local Time, Standard Error: Standard error (bottom): Fraction of days with detected industrial odor: December 2014 to February 2015, 11am to 1pm Local Time: Fraction of days with noticeable industrial odor, modeled using ordinary Kriging Dots show locations of the 19 stations used to produce the interpolated map above; standard error is below. Units for both are fraction of days with detected industrial odor. Maps from Wright et al.
