Future projections of daily maximum 8-hour average ozone exceedances of 60, 70, or 75 ppb levels in summer (JJA) over the Northeastern U.S.A. [Rieder et al., 2015]

Follow the link above to download csv files, provided separately for each threshold value (60, 70, 75 ppb) and for four time periods (2006-2015, 2026-2035, 2046-2055, 2091-2100) and two sets of simulations: RCP4.5 and RCP4.5_WMGG from bias-corrected GFDL CM3 simulations (each grid cell is an average of 3 ensemble members).  RCP4.5_WMGG is identical to the RCP4.5 scenario except that air pollutant emissions are held fixed at 2005 levels, in order to isolate the role of climate change occurring from well-mixed greenhouse gases.   These files include the values shown in Figures 4 and 6 of Rieder et al., JGR, 2015, and provided in the supplementary material, with some additional time periods included here for completeness.

 

Future projections of 1-year summertime (JJA) return levels of daily maximum 8-hour average ozone over the Northeastern U.S.A. [Rieder et al., 2015]

Follow the link above to download csv files, provided separately for each of four time periods (2006-2015, 2026-2035, 2046-2055, 2091-2100) and two sets of simulations: RCP4.5 and RCP4.5_WMGG from bias-corrected GFDL CM3 simulations (each grid cell is an average of 3 ensemble members).  RCP4.5_WMGG is identical to the RCP4.5 scenario except that air pollutant emissions are held fixed at 2005 levels, in order to isolate the role of climate change occurring from well-mixed greenhouse gases.   These files include the values shown in Figures 5a-d and 7a-c of Rieder et al., JGR, 2015, and provided in the supplementary material, with some additional time periods included here for completeness.

1-year and 5-year Surface Ozone Return Levels at EUS CASTNet Sites [Rieder et al., 2013]

Follow the link above to download a csv file containing the 1- and 5-year return levels for 1988-1998, 1999-2009, and  2003-2009 derived from summertime maximum daily 8-hour average (MDA8) at Eastern U.S. CASTNet measurement sites.  These are the values shown in Figure 3 of Rieder et al., Environ. Res. Lett, 2013; please refer to the published manuscript for more detail.
