This dataset contains global removal methane simulation measurements from the UK Earth system models (UKESM1) model using UK Chemistry and Aerosol (UKCA) coupled with Joint UK Land Environment Simulator (JULES) and Model of Ecosystem Dynamics, nutrient Utilisation, Sequestrationand Acidification (MEDUSA). Using UKESM1, a series of simulations of methane removal were run until 2100.

The measurements include globally averaged data for methane emissions, surface temperature, and surface ozone at a monthly time period. This was completed using the new emissions-driven configuration of UKESM1. Model resolution is N96L85-ORCA1 with 85 vertical levels. Wetland methane emissions are interactively coupled to UKCA. (More details available in Sellar et al 2019 and Folberth et al 2021). The different columns are different simulations. These can be broken down into two broad categories: those based on SSP1-2.6 and those based on SSP3-7.0.

For each SSP, we created a set of methane removal simulations with the modified prescribed methane emissions shown in the corresponding columns. These were for the base SSP, a series of different removal amounts (0.25, 0.5, 0.75, 1, 1.5, and 2.0 x the removal in SSP3-7.0LowCH4) and a series of different timings for the start of removal (2020, 2030, 2040, 2050). For each simulations, global means surface temperature and ozone are gathered in this data. Location extent is full global average.
