Absorption of direct solar radiation by the atmosphere

Figure 6

1. The shortest wavelenths of the solar spectrum, the ultraviolet < .12 microns are absorbed by oxygen and nitrogen in the upper atmosphere above 100 kilometers.
2. UV radiation between between .12 and .18 microns are absorbed by oxygen above 50 kilometers.
3. UV radiation between .18 and .34 microns are absorbed between 50 kilometers and 10 kilometers by ozone.
4. The atmosphere is nearly transparent to visible radiation between .34 and .7 microns.
5. The infrared part of the solar spectrum is partially absorbed by water vapor in the troposphere below 10 kilometers.
