Mean peak temperature (°C), mean heat duration (seconds above 60 °C), and heat dose (°C·sec, calculated with a baseline of 0 degrees) measured 1 cm above ground level as a function of variation in fuel loads for prescribed burns in the shortgrass steppe of northeastern Colorado during 2007 to 2013. Lines show predictions based on the fuel load coefficient in fitted models reported in Table 2.
