Method & Evidence

AimTo describe and evaluate the advancements in the Met Office Unified Model (UM) and JULES land surface model configurations (GA7.0/GL7.0 and GA7.1/GL7.0) for improved accuracy in simulating atmospheric and land surface processes.

MethodModel development and evaluation

ProcedureThe study details the scientific configurations of the Met Office Unified Model (GA7.0/GA7.1) and the JULES land surface model (GL7.0). It outlines incremental developments and targeted improvements addressing identified critical errors in previous configurations, such as precipitation biases over India, tropical tropopause layer temperature and moisture biases, energy non-conservation in the advection scheme, and surface radiation biases over the Southern Ocean. New parametrizations for aerosols (UKCA GLOMAP-mode) and snow (JULES multi-layer snow) were also incorporated. The GA7.1 branch configuration was developed to reduce anthropogenic aerosol effective radiative forcing biases present in GA7.0.
