For work levels of 250 kilocalories/hour. <br /> b. Calculate the adjusted air temperature (ta adj) by using the equation: <br /> to adj o F + (13x(%/100)sunshine). Measure air temperature (ta) with a standard mercury-in-glass <br /> thermometer, with the bulb shield from radiant heat. Estimate percent sunshine by judging what percent of the <br /> time the sun is not covered by clouds that are thick enough to produce a shadow (100% sunshine = no cloud <br /> cover and sharp distinct shadow; 0% sunshine = no shadows). <br /> C.
