ACSIS The North Atlantic Climate System: Integrated observationS, attribution and prediction

The North Atlantic Climate System Integrated Study:ACSIS

Major changes are occurring across the North Atlantic (NA) climate system: in ocean and atmosphere temperatures and circulation, in sea ice thickness and extent, and in key atmospheric constituents such as ozone, methane and aerosols. Many observed changes are unprecedented in instrumental records. Changes in the NA directly affect the UK’s climate, weather and air quality, with major economic impacts on agriculture, fisheries, water, energy, transport and health. The NA also has global importance, since changes here drive changes in climate, hazardous weather and air quality further afield, such as in North America, Africa and Asia.

ACSIS has been fully funded for five years (2016-2021) through NERC's Long Term Science commissioning, which aims to encourage its research centres to work closely together to tackle major scientific and societal challenges. ACSIS is one of the projects funded through this new way of allocating national capability funding, designed to enable more ambitious science than any single research organisation could provide.

Primavera is a European Union Horizon2020 project which aims to develop a new generation of advanced and well-evaluated high-resolution global climate models, capable of simulating and predicting regional climate with unprecedented fidelity, for the benefit of governments, business and society in general.

The PRIMAVERA kick-off meeting took place at the Met Office between 23 and 26 November. The first half was held jointly with the companion project, CRESCENDO, while the second half was dedicated to PRIMAVERA and HighResMIP planning. Participants from the 19 institutions across Europe discussed around the five PRIMAVERA Themes and initiated work package interactions on process-based metrics and designing the simplified forcings that will be applied to HighResMIP experiments.

Coupled Model Intercomparison Project Phase 5 - CMIP5 is a standard experimental protocol for studying the output of coupled ocean-atmosphere general circulation models. It provides a community-based infrastructure in support of climate model diagnosis, validation, intercomparison, documentation and data access. For more information visit the CMIP5 overview page

The UK Earth System Modelling Long-Term Science Multi-centre program:UKESM-LTSM



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 will realize the development and evaluation of a world-leading ESM and ensure this model is fully applied to a range of Earth system science questions, as well as delivery of robust Earth system change projections to support the UK government and public.

Coordinated Research in Earth Systems and Climate: Experiments, kNowledge, Dissemination and Outreach: CRESCENDO


CRESCENDO is a European Union Horizon 2020 Project that started in November 2015 and runs for five years. The primary aims of CRESCENDO are to improve the representation of key processes in European Earth system models, to thoroughly evaluate the scientific performance of these models and to use the models to generate a new set of Earth system projections for the coming century.

This project finished in 2009 - UK-Japan Climate Collaboration: The aim of the UJCC project is to exploit the power of the Earth Simulator to produce world-leading climate simulations. The science of the project will then be to understand how the increased resolution changes the large scale mean climate. 

ERA: ERA-Interim is the latest ECMWF global atmospheric reanalysis of the period 1989 to present. Read More at the ERA ECMWF page

UKCA: Our objective is to develop, evaluate and make available a new UK community atmospheric chemistry-aerosol global model suitable for a range of topics in climate and environmental change research.

The Joint Weather and Climate Research Programme (JWCRP) facilitates research between the Met Office and NERC. Its overarching goal is to ensure the UK maintains and strengthens its leading international position in weather and climate science. 

The JWCRP has two major elements. The first is a joint commitment to sustaining and growing the UK's national capability in observing, understanding, modelling and predicting weather and climate, along with the infrastructure required to deliver that national capability. The second is to align major research initiatives and programmes to ensure the most effective impact of the research and pull-through into the delivery of services to government and business.

Atmospheric methane (CH4) is the second most important greenhouse gas, and has a short lifetime when compared to CO2. Reductions in emissions of methane could bring about rapid reductions to the amount in the atmosphere with immediate benefits for climate. Arctic greenhouse gas sources need to be quantified and their vulnerability to change assessed.

The Methane in the Arctic: Measurements and Modelling (MAMM) project combines ground and aircraft based measurements of methane in the Arctic with regional and global computer modelling. It aims to understand current methane emissions and to simulate the impact of future climates on Arctic emissions.
