Solar Ultraviolet Data
The ultraviolet (UV) part of the electromagnetic spectrum ranges between 5 and 400 nanometers (nm). As the SORCE (Solar Radiation and Climate Experiment satellite) mission states, far UV irradiance from the Sun varies by as much as 10 percent during the Sun’s 27-day rotation, while the bright 121.6 nm hydrogen Lyman-alpha emission may vary by as much as a factor of 2 during an 11-year solar cycle, dramatically affecting the energy input into the Earth’s atmosphere. Water vapor and ozone are especially sensitive to changes in the solar UV radiation. Different wavelengths of solar radiation are absorbed at different altitudes in the Earth’s atmosphere, affecting different physical processes. As Dr. Jack Eddy notes, we utterly depend on solar radiation. Long term monitoring of its variations over all wavelengths is critical to our understanding of the impacts on our environment.
