It can also be used in remote measurements of the temperature of clouds and the sky. Sky temperature is a function of how much water vapor is present to reflect heat back to earth. A clear dry sky reads lower temperature, a cloudy overcast sky reads higher temperature. Just aim the unit straight up and press the button to take sky temperature and cloud temperature measurements. Low sky temperature below 40 F on a clear cool night can indicate frost is possible, for example. Clouds are warm, and also reflect heat back to earth, so on an overcast night the temperature of the clouds likely will be near the minimum low temperature for the morning if the weather is otherwise stable.
