). Solar radiation 

requires the solar radiation sensor.

UV (Ultra Violet) Radiation

Energy from the sun reaches the earth as visible, infrared, and ultraviolet (UV) 
rays. Exposure to UV rays can cause numerous health problems, such as sun-
burn, skin cancer, skin aging, cataracts, and can suppress the immune system. 
The Vantage Pro2 helps analyze the changing levels of UV radiation and can 
advise of situations where exposure is particularly unacceptable. UV radiation 
requires the UV radiation sensor. The Vantage Pro2 displays UV readings in 
two scales: MEDs and UV Index. 

Note: 

Your station’s UV readings do not take into account UV reflected off snow, sand, or 
water, which can significantly increase your exposure. Nor do your UV readings  take 
into account the dangers of prolonged UV exposure. The readings do not suggest 
that any amount of exposure is safe or healthful. Do not use the Vantage Pro2 to 
determine the amount of UV radiation to which you expose yourself. Scientific evi-
dence suggests that UV exposure should be avoided and that even low UV doses 
can be harmful.

UV MEDs

MED (Minimum Erythemal Dose) is defined as the amount of sunlight expo-
sure necessary to induce a barely perceptible redness of the skin within 24 
hours after sun exposure. In other words, exposure to 1 MED will result in a 
reddening of the skin. Because different skin types burn at different rates, 1 
MED for persons with very dark skin is different from 1 MED for persons 
with very light skin.

Both the U.S. Environmental Protection Agency (EPA) and Environment Canada have 
developed skin type categories correlating characteristics of skin with rates of sunburn.
