Parameter tuning for UKESM1

We are nearing the completion of UKESM1 development, with the planned science capabilities now included and all components coupled together. What remains before finalising the model is to calibrate the fully coupled system to achieve good performance across a range of observed climate indicators, such as radiative fluxes, temperature and rainfall. This calibration step is […]

Atmospheric Chemistry in UKESM1

Atmospheric trace gas constituents and aerosols exert important influences on global-scale and regional-scale climate. Atmospheric chemistry determines the abundance and lifetime of many greenhouse gases. In the stratosphere, heterogeneous chemistry involving reactive chlorine causes ozone (O3) depletion while, in the troposphere, reactive gases such as carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs) perturb […]

UKESM at the Crosscurrents Poetry Event

The Crosscurrents event was a marine science and poetry event held at Plymouth Marine Laboratory (PML) in March 2017. At the event, five scientists were paired up with five local poets. The scientists were tasked with presenting their research and the poet shared one or more poems inspired by the science. On the night of […]

Coupling Technologies for Earth System Models Workshop report

The fourth workshop on Coupling Technologies for Earth System Models was held at Princeton University on March 20-22 (see https://www.earthsystemcog.org/projects/cw2017/). Richard Hill and Jeremy Walton attended from the UKESM core group; our Met Office colleagues Jean-Christophe Rioual and Mike Hobson were also at the meeting.

European Geosciences Union General Assembly report

The European Geosciences Union (EGU) General Assembly 2017 was held in Vienna on 23-28 April (see http://www.egu2017.eu/). Lee de Mora and I attended from the UKESM core group; several other colleagues from the Met Office and NERC were also at the meeting.
