A new simulated climatology of the atmospheric radiation
A simulation experiment is conducted to inquire into the mean climate state and likely trends in atmospheric infrared radiation. Up- and down-welling spectra at five vertical levels from surface to the top of the atmosphere are rigorously calculated from climate model simulated atmosphere for a 25-year period. Tracing the radiation flux vertically and spectrally renders a dissection of the greenhouse effect of the Earth atmosphere and its change due to climate forcings and feedbacks. This paper underscores the stratosphere’s radiative-energetic role in transient climate variations, quantitatively measures the time it takes to detect various aspects of climate change from spaceborn radiometric measurements, and suggests a new way for monitoring long-term changes in stratospheric water vapor.
