Starting the CMIP6 simulations with HadGEM3 GC3.1
Following finalization of the scientific evaluation of HadGEM3 GC3.1 (see UKESM newsletter no.4), the first set of “production” runs for the CMIP6 model intercomparison (Eyring et al., 2016) have now begun. These are being performed at the two spatial resolutions of HadGEM3 GC3.1: N96ORCA1 (CMIP6 tag: HadGEM3-GC31-LL) and N216ORCA025 (HadGEM3-GC31-MM). The former of these 2 […]
Progress towards interactive Ice Sheets in UKESM1
There is currently an intense focus in the UKESM development group on finalising the 1st version of UKESM that will be used for the majority of CMIP6 runs that start early next year. But there will be more than one configuration of UKESM, each with different strengths, designed to explore different science questions. One of […]
Results from the Royal Society Summer Science Exhibition visitors’ survey
In order to evaluate the effectiveness of communication at our stand, ‘A Model Earth’, at the Royal Society Summer Science Exhibition (3rd to 9th July 2017) and to observe trends in opinions and knowledge of climate science amongst exhibition visitors, a survey was conducted over the course of the exhibition week. The aim was to […]
Representing UKESM at CERN
Before I started working in the UKESM project, I worked on an entirely different project: the ATLAS experiment at CERN. CERN is the European Organization for Nuclear Research: it is the largest particle physics laboratory in the world and hosts the Large Hadron Collider, as well as many significant physics experiments. Between 2006 and 2010, […]
Final steps to UKESM1
INTRODUCTION As discussed in the 5th UKESM Newsletter (Sellar et al.2017, Parameter tuning for UKESM1, newsletter no. 5), over the past 12 months we have been working intensively on the scientific calibration of UKESM1, an important and necessary final step when a set of complex component models are coupled together into a fully coupled Earth […]
UKESM at the Royal Society Summer Science Exhibition, 3-9 July 2017 London
In the first week of July 2017, The Royal Society held their annual flagship Summer Science Exhibition, in the society’s home in London. Consistently attracting tens of thousands of curious visitors each year, the exhibition remains as prestigious as it was at its creation, and an incredible opportunity for members of the scientific community to […]
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 […]
