Monthly-mean radiative forcings following an increase in methane from 750 ppb to 1800 ppb

Monthly-mean radiative forcings following an increase in atmospheric methane from 750 ppb to 1800 ppb. Forcings are calculated at a 5 degree by 5 degree spatial resolution by the radiative transfer code SOCRATES-RF following the method stated in Byrom and Shine (2022) (see related publication for citation). This dataset is used to derive methane's instantaneous shortwave radiative forcing and its total shortwave radiative effect (i.e. including the impact of methane's shortwave absorption bands on methane's longwave stratospheric temperature adjusted radiative forcing). These calculations include satellite measurements of methane's distribution and spectrally-varying surface albedo, and include absorption of solar mid-infrared radiation by methane's 7.6 micron band.
