| Winter Inversion
Winter inversions are common in cold-weather climates in
valley areas such as Rutland, VT. Below are a couple of time-series graphs
of PM2.5 hourly measurements from Burlington, Rutland and Bennington,
VT from late-December 2002. Rutland is located in a valley while Burlington
and Bennington are not. As the temperature drops and an inversion is created
in Rutland, the PM2.5 concentrations build while they remain
low in the areas (Burlington, Bennington) not affected by the inversion.
