Measure air temperature (ta) with a standard mercury-in-glass <br /> thermometer, with the bulb shielded from radiant heat. Estimate percent sunshine <br /> by judging what percent time the sun is not covered by clouds that are thick enough <br /> to produce a shadow. (100 percent sunshine = no cloud cover and a sharp, distinct <br /> shadow; 0 percent sunshine = no shadows.) <br /> c A normal work ensemble consists of cotton coveralls or other cotton clothing with <br /> long sleeves and pants. <br /> oZ <br />
