     ## AOD Timeseries for Galveston Bay
-    [The timeseries for Galveston Bay just east of downtown Houston illustrates a decreasing trend in AOD from 2000 to 2019. This decreasing trend in AOD could be attributed to factors such as policy changes from the EPA that inhibit increased emissions from power plants. The p-value for this analysis is 0.005 aligning with the significant trend. A p-value represents a statistical analysis that shows whether a trend is occurring due to random chance or a real pattern. A low value such as this represents a real pattern occurring.]
+    The monthly and spatially averaged time series of AOD for Galveston Bay (just east of downtown Houston) show a statistically significant (p < 0.005) decreasing trend in AOD from 2000 to 2019. Note the measure of statistical significance of p < 0.005 indicates that there is a very high confidence that the decreasing trend in AOD is real and not due to chance. This decreasing trend in AOD could be attributed to stringent air quality regulations implemented as a part of the Clean Air Act.

     ## AOD Timeseries for Western Houston
-    [The following timeseries illustrates the change in AOD from 2000 to 2019 in the western Suburbs of Houston, TX where the urbanization was the greatest and the difference in AOD is high (see background map). In comparison to the Baytown timeseries, the trend for this particular area is slightly higher. This could be attributed to increased industrial activity leading to increased emissions. There is no significant increase or decrease in the western Suburbs of Texas. Note that while there may be more policies implemented by the EPA to reduce emissions, an increase an urbanization could be the cause of no decreasing trend in AOD.]
+    Unlike the Galveston Bay area, the monthly and spatially averaged time series of AOD for the Western Suburbs of Houston, TX shows a trend where there is a small, statistically insignificant increase over the time period of 2000 to 2019. Note that the spatial pattern of difference in decadal mean AOD between the second and first decade of this century shows a localized increase that correlates to urbanization. Thus the trend of a small increase in AOD time series could be due to vehicular and other urban sources of pollution counteracting the effects of the Clean Air Act.
