摘要: Calculations of air-mass factors (AMFs) for ground-based zenith-sky UV-visible spectrometers are presented and discussed. Causes size errors in AMFs ozone the visible evaluated. Errors can be caused by approximations calculation (intensity-weight approximation, ignoring finite field view instrument); approximation scheme (single scattering, refraction); or variable geophysical parameters (vertical profile constituents). These relative AMF cause identical vertical columns deduced from measurements spectrometers. The mean due to using one set all seasons locations is ±2.4% when averaged over commonly used range solar zenith angles.
