I am a class 9 student studying the UV light
in different parts of world.
Do you have any data on UV light concentrations,as measured by a
photometer, in different countries.
Like so many inquiries, the answer depends upon how sophisticated an answer
one is looking for. For example, the website
http://www.geog.ouc.bc.ca/physgeog/contents/6i.html discusses the effect of
[insolation], the angle of incidence, the length of the day, and the annual
changes in solar radiation [of all wavelengths] striking the earth. In
addition, the altitude of the site, the number of sunny/cloudy days per
year, the wavelenth of U.V. radiation. So the response can be pretty
With that caveat, there are two other websites [with many links] that
address this question directly:
The acronym SUMER stands for Solar Ultraviolet Measurement Emitted
Radiation. I think that Aniketh can browse these sources and with her
teacher decide just how sophisticated an answer is needed.
