Fig. 2: Daily average (hourly) temperature and relative humidity.

a DCA temperature, b National Arboretum temperature, c DCA relative humidity, d National Arboretum relative humidity point value comparisons at the grid cells containing each of the measurement locations simulated with WRF using 10 m (red line) and 100 m (blue line), NUDAPT 1 km (green line), and no (gray line) morphology inputs for the Washington, DC area for 1–10 July 2010. Observations are shown in black (dashed line). Daymet grid cell daily values are in magenta (dot-dash line). Temperature observations from the National Arboretum, in this case, are for observations that occurred sometime during each day between the minimum and maximum temperatures, but are not necessarily averages.
