Spinning up marine biogeochemistry in UKESM1

Graph of the Antarctic Circumpolar currentAs part of the UK's preparations for CMIP6 - and to specifically address the ocean's carbon cycle - spin-up simulations of the low resolution version of UKESM1 (UKESM-lr) have been planned and now begun. To this end, the marine carbon cycle of UKESM1-lr has been initialised from estimated pre-industrial conditions and has been spinning up in ocean-only mode using atmospheric forcing (including winds, radiation, heat and freshwater fluxes) derived from an atmosphere-land simulation that employed sea surface temperatures (SST), sea-ice (SIC) and atmospheric gases, including CO2, representative of pre-industrial conditions.

Nitrogen and the Terrestrial Carbon Cycle in UKESM1

Simulated nitrogen depositionOne key aspect of Earth System Models (ESM) that distinguishes them from their (physical) Global Climate Model (GCM) relations is the inclusion of interactive biogeochemical processes, such as the carbon cycle. An important additional phenomenon, generally not included in the current generation of ESMs, is the role nutrients play in plant productivity. Most current generation ESMs assume no nutrient limitation in their simulation of carbon cycle responses to increasing atmospheric CO2 and a changing climate. UKESM1 will include a representation of the terrestrial nitrogen cycle.

Implementing the CMIP6 data request

Snapshot of part of the CMIP6 data requestThe World Climate Research Program's Coupled Model Intercomparison Project (CMIP) aims to improve our understanding of, and ability to simulate, key climate phenomena and future climate change using a coordinated multi-model approach. The UK contribution to CMIP6 will be made through a collaboration involving the Met Office, NERC centres and UK universities. It will use the UKESM1 earth system climate model and the GC3.1 configuration of the HadGEM3 physical climate model.

The UKESM LTSM project kick-off meeting

Close to 40 scientists involved in the NERC-funded UKSM Long Term Science Multi-centre (LTSM) project recently met at the University of Reading (July 4-5th) to begin work on this exciting new project. Participants from all eight of the NERC centres, as well as the Met Office Hadley Centre (MOHC), attended the meeting enabling an extremely productive start to the project.

ACSIS Kick-off meeting on 5 Dec at the Wellcome Auditorium in London

The North Atlantic Climate System Integrated Study: ACSIS, has been fully funded for five years (2016-2021) through NERC's Long Term Science commissioning, led by NCAS Director for Climate, Professor Rowan Sutton. Its kick-off meeting will be held on the 5th Dec at the Wellcome Auditorium in London with the theme "Recent trends in the North Atlantic Climate System".
