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.

The UKESM-LTSM project celebrates its kick-off meeting on the 4th and 5th July 2016 at the University of Reading

The UKESM project brings together the unique climate modelling capabilities of the Met Office Hadley Centre (MOHC) with a wealth of advanced Earth system modelling (ESM) and observational capabilities from 8 NERC centres (NCAS, BAS, BGS, CEH, CPOM, NCEO, NOC and PML). Carried out in active collaboration with the broader NERC research community, the project […]

Spinning up marine biogeochemistry in UKESM1

To a first approximation, much of what happens in the Earth system depends on the dynamics and interactions of the two key geophysical fluids that make it up: the atmosphere and the ocean. As anyone familiar with the UK’s weather will attest, the atmosphere is flighty and dynamic, with perturbations in temperature, humidity or chemical […]
