Abstract
The radiative forcing due to methane is estimated from the analysis of upwelling thermal radiation (UTR) fluxes calculated with the use of MODTRAN radiative code for five climate atmospheric models and three methane content values: preindustrial (0.8 ppm), current (1.8 ppm), and future (2.5 ppm). The current values of UTR flux are ∼0.15% lower as compared to the preindustrial era. Seasonal and spatial variations in UTR fluxes attain ∼13% at the current methane content. The radiative forcing due to the growth of atmospheric methane since the preindustrial era is estimated at −0.482 to −0.266 W/m2.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
