Dataset
UKESM1-CH4 output under current legislation and global methane pledge scenarios
Abstract
This dataset contains model output for experiments using the UKESM1-CH4 emissions-driven configuration of the UK Earth System model (Folberth et al. 2022, DOI:10.1029/2021MS002982). The simulation follows the experimental design of the SSP2-4.5 Shared Socioeconomic Pathway, except with methane emissions following the current legislation scenario from the ECLIPSEv6b inventory, and a global methane pledge scenario where emissions are reduced globally by 30%, with a heterogeneous reduction regionally. These simulation span 2016-2049 and use a coupled atmosphere-ocean climate model. The data comprise annual mean output over the experimental period for ozone, methane, hydroxyl radical, precipitation and provided diagnostic air mass and diagnostics suitable for the calculation of the methane lifetime and budget. Mean daily 8h maximum ozone is also provided for 2049.
