TL;DR: The United Kingdom Earth System Model UKESM1 as discussed by the authors was developed and tuned to achieve acceptable performance in key physical and Earth system quantities, and discuss the challenges involved in mitigating biases in a model with complex connections between its components.

TL;DR: In this article, a description of the tropospheric chemistry component of the UK Chemistry and Aerosols (UKCA) model has been coupled to the Met Office Hadley Centre's HadGEM family of climate models.

TL;DR: The scientific and technical implementation of two models for a core set of experiments contributing to the sixth phase of the Coupled Model Intercomparison Project (CMIP6), using the physical atmosphere-land-ocean-sea ice model HadGEM3-GC3.1 and the Earth system model UKESM1.

TL;DR: In this paper, the authors evaluate the aerosol schemes as implemented in the physical and Earth system models, HadGEM3-GC3.1 and UKESM1, which are contributing to the 6th Coupled Model Intercomparison Project (CMIP6).

TL;DR: In this article, a global chemistry-climate model is used to assess the impact on atmospheric composition of the regeneration and recycling of H Ox in the photo-oxidation of isoprene.
