Air temperature is always measured in a shady location because in the shade the thermometer is measuring the actual air temperature, and only the air temperature. A thermometer placed in the sun measures the temperature that the sun heats the thermometer to, not the true air temperature.
Simply so, should you put a thermometer in the shade or direct sunlight Why?
The thermometer must be placed in the shade. If you put your thermometer in full sunlight, direct radiation from the sun is going to result in a temperature higher than what it should be. … Place the thermometer over a grassy or dirt surface. Concrete and pavement attract much more heat than grass.
Also, how much does direct sunlight affect the temperature of an object?
How does shade affect temperature? Standing in direct sunlight exposes you to solar radiation, which makes the air feel 10-15 degrees warmer than the actual temperature. Temperatures are closer to actual air temperatures when you’re in the shade.
How many degrees does shade lower?
Temperature in the Sunlight. In the shade, you may feel 10-15 degrees cooler, but the temperature is the exact same as the temperature in full sunlight. Shade only feels cooler because you are avoiding solar radiation. In reality, the temperature in the sun is the same as the temperature in the shade.
Shaded areas remain warmer than those exposed to the sky. The surface cools at night because energy from sunlight is radiated out to space in the 10-micron (wavelength) region of the spectrum. … As a result, they stay warmer at night.
Answer: For the most accurate reading, use a liquid-in-glass or a digital thermometer. Place it so that it is not in direct sunlight at any time. The shade of a tree and a north-facing porch are two good places. Place the thermometer four to six feet above the ground in an area where there is sufficient airflow.
Shade doesn’t actually make temperatures cooler. Rather, being in direct sunlight and solar radiation makes the air feel 10 to 15 degrees warmer than it actually is, said Jim Lushine, a retired weather service meteorologist. “So, conversely, it would feel that much cooler in the shade,” he said.
Direct sunlight is more concentrated heat, which tends to be warmer but also covers a smaller surface area. … Indirect sunlight is more diffuse and it also covers a broader surface area. This comes at the cost of temperature; cold winters are partially an effect of indirect sunlight.
