The answer depends on why you want to measure the temperature and what the object is. I cannot see any way of measuring the temperature of the surface of the sun in the shade!
It like 20' on the moons shade
If it's in the shade, then the temperature of the air that wafts past it is. If it's in direct sun, then it's displaying the temperature of the structure of the thermometer itself, as it absorbs direct solar radiation and its temperature rises above that of the air that wafts past it.
temperature is measured in degrees celsius or Fahrenheit
it is measured by a thermometer
the shade in cooler and the sun is warmer.
Air temperature can be measured beyond the troposphere.
Air temperature can be measured beyond the troposphere.
The surface temperature can be estimated quite precisely from the color of the light. The temperature of the core can't be measured as directly, and must be estimated based on our knowledge of how stars work.
in a shade
NO ... Barometric Pressure is measured in Centimeters or Inches (of Mercury.) Temperature is measured in Degrees Fahrenheit or Degrees Centigrade.
Approx 100. As a rule of thumb, generally 20 degrees cooler in the shade or so they say.
Depends on you
