WebThe exo-atmospheric solar spectral irradiance is a well-known quantity and for flat terrain the incident angle is readily obtained. For non-flat terrain, calculation of the incident angle at each pixel requires a DEM at the same GSI as the sensor image.
WebThe magnitude of the exoatmospheric irradiance at the top of the Earth’s atmosphere (E 0,[W m − 2 μ m − 1]) is a function of the spectral exitance of the sun and the Earth–Sun distance. The atmosphere attenuates the solar beam irradiance via gaseous absorption and molecular and aerosol scattering [ 22 , 23 ]. toddler red thermal shirtWebNov 15, 2013 · E BJ is the band-averaged exoatmospheric solar irradiance of Beijing-1/MS (in W/(m 2 μm)); ...
