$Afternoon-averaged daily mole fractions and wind speed for 1 – 28 January 2013. a) CO2, b) CH4 and c) CO. The data from the tallest measurement height at each tower is used; the measurement heights range from 39 to 136 m AGL (Table 1). Other site details are listed in Table 1 as well. d) Wind speeds (WS) measured at the Indianapolis airport for all hours (blue dots) and afternoon-averaged (red line).
