Averaged 4 highest 8 hour ozone concentrations
The number of 8hr exceedances for 2004. Similar
to 2003, the 2004 summer was another year of good
air quality and low ozone exceedance days
With few exceptions, urban and coastal
monitoring sites were the only areas that
experienced ozone levels high enough to exceed
the 8-hr standard in 2004.

Figure 6 REIP vs. Ozone All New Hampshire
Schools.

• In 2005, mean monthly max ozone decreased and
  REIP remained elevated
• High REIPs in 2005 indicate healthy pine needles
  with high amounts of chlorophyll
• In 2005, high REIP values corresponded to low
  ozone values as they have in most years
• since Forest Watch began.2004 and 2005 are our
  highest REIP values.
• REIP is rising over time, Our white pines are
  getting healthier!
