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.
