Testing broadband radiation schemes for their ability to calculate the radiative forcing and temperature response to stratospheric water vapour and ozone changes

摘要: The radiative forcing and fixed dynamical heating temperature response is calculated for observed changes (1979-1997) in carbon dioxide, stratospheric ozone water vapour, using several radiation schemes. It found that certain broadband schemes substantially underestimate the absorption by vapour up to 50%, instantaneous forcing, 15% adjusted forcing. This error leads a 30% smaller also causes an of 50%. was this could be corrected splitting wavelength band which accounts strong into two separate bands. work illustrates need carefully test each new introduced scheme, as its designer may not have catered such eventualities.
