5. Averaged 4 highest 1 hour ozone concentrations & The number of
1hr exceedances for 2003.
Many stations recorded zero exceedances in 2003 at the 1hr standard.
Southern New England, especially coastal areas were the only exceptions.

6. 2003 & 2004 both had the fewest exceedance days in over 20 years.

8-hr standard. Source :
2003 & 2004 both had the fewest exceedance days in over 20 years.

9. Contributions of Ozone Precursor Pollutants in New England (2002)
The automobile is directly and indirectly
responsible for more than 50% of emissions of
VOC’s and NOX in New England.
Steps we can take as individuals:
Hybrid technology!
Less driving on hot days
Public transportation
Regular vehicle maintenance
Avoid gas fill ups during hot weather

10. The inverse relationship between REIP and ozone returned in 2002 and 2003.
In 2003, high REIP values corresponded to low ozone values as they have in most years
since Forest Watch began.
In 2003 we saw our highest REIP values since Forest Watch began.
Spearman’s coefficient of correlation: (1998 = -0.81) (2002 = -0.39) (2003 = -0.51)
Probability: = < = < = <0.05

14. Average Annual Red Edge Inflection Point for All Schools
The overall trend shows increasing REIP values between 1993 and 2003
-Increasing CO2 in the atmosphere? (increased rate of DBH)
-Younger Forest Watch trees replacing older ones? (resistance)
-Improvements in Air Quality? (Clean Air Act Amendments of 1990)

15. TM 5/4 Moisture Stress Index
TM 5/4 is a measure of water content.
Lower TM 5/4 = More water
<0.55 = Adequate Moisture
= Initial Moisture Stress
>0.60 = Increasing Stress
Our two highest REIP years for all schools in 1999 and 2000 were our lowest 5/4 years.
2000 was very wet, 1999 was a significant drought year, however spring conditions were very wet in 1999.
2001 and 2002 were drought years; TM5/4 values increased signifying less water.
In 2003, cooler and wetter conditions led to a slight decrease in 5/4 values

16. NIR 3/1 Provides us with information about the developmental status of vegetation
Values <0.9 are indicative of young, rapid growth
Values from .9 to 1.0 equal indicate slow growth and maturity
Values greater than 1.0 signify increasing senescence
The trend of increasing vigor and young growth correlates well with the
Rise in REIP values seen between 1993 and 2003.
This trend could also be related to the loss of older trees sampled in
Forest Watch And the corresponding increase in younger more
sampling accessible trees.
1999 and 2000 show the lowest values in 3/1 and 5/4 index values as well as
High REIP values

20. Figure 21: Percent of needles with both chlorotic mottle and tip necrosis 1996-2003.
This decline in the presence of both symptoms correlates well with the increase in REIP over time.
