Direct solar irradiance, spectral transmission and atmospheric up well radiance under certain circumstance of atmosphere and radiation are also computed in virtue of software LOWTRAN7.
Sunphotometer is designed to measure the direct solar irradiance for retrieving the amount of the vapor of water, ozone and nitrogen oxide etc. in the atmosphere.
