EVA

Earth system modelling of climate Variations in the Anthropocene

01/2014 - 12/2017

RCN

http://www.uib.no/eva

 

In EVA, the Norwegian Earth system model (NorESM) as the main national facility for global climate studies will be further developed, extended, quality checked, and applied to key research questions in the field of climate science. In particular, NorESM2 will be established also for participation in key international assessments. NorESM experiments on drivers for climate variability will be carried out, and related feedbacks will be quantified addressing key uncertainties. Complex spatio-temporal structures of the climate system will be analysed including interactions between physical processes and biogeochemical cycles. The planned pre-industrial, historical, and future NorESM simulations together with observational evidence provide the foundation for discriminating between natural and human-induced climate variability. EVA is firmly embedded within the international scientific research field. NorESM is provided as a major national infrastructure for large-scale predictive climate studies. Results and data sets will be open to all end-users (scientists, policy makers, and the public). For adaptation and mitigation purposes, data will be made available through the National Climate Service Centre. (text: EVA project; coordinator: C. Heinze)

 

ORGANIC

Overturning circulation and its implications for global carbon cycle in coupled models

01/2015 - 12/2018

RCN

 

ORGANIC will study the physical and biogeochemical interactions in the climate system using state-of-the-art model system. The project will enhance our knowledge in climate variability simulated by the NorESM model and identify uncertainty that comes with its future projections. The focus is to elucidate the linkage between large scale overturning circulation with the biogeochemical cycling in the ocean. This link is necessary since hydrography tracers such as temperature and salinity do not give us a comprehensive overview on the overturning circulation. On the other hand, biogeochemical tracers such as nutrient and CFCs are closely tied to the ocean circulation and can be used as indicators for patterns and ventilation rates of the ocean. Due to the non linear interactions between climate and ocean carbon cycle, it is vital for an Earth system model to accurately simulate the relevant former and latter processes individually as well as interactively in order for it to produce a sound future climate projections. The outcome of ORGANIC will be highly relevant for both global and regional climate studies, particularly in regions where the ocean ventilation will be perturbed by anthropogenic forcing. The proposed interdisciplinary work will involve scientists from natural, mathematical and computational scientists. The study utilizes the nationally developed Norwegian Earth system model and observational sets from contemporary and paleo periods. The methods that will be developed throughout the project, the Matrix Free Newton Krylov, will provide novel and efficient approach to increase our understanding in the sophisticated interactions between the physical and biogeochemical processes in the climate system.

SNACS

Subpolar North Atlantic Climate States

01/2014 - 12/2016

RCN

www.snacs.no

 

SNACS will take a multidisciplinary approach and use data from high resolution sedimentary archives, ocean surveys and state of the art Earth System Models (ESMs) to unravel the subpolar North Atlantic variability of past times, its expected future behaviour and the feedback on the carbon cycle.

VENTILATE

Ventilation age and remineralisation rates in polar and sub-polar regions as an indicator for climate change

01/2014 - 01/2018

RCN

 

The project aims to increase our understanding of the link between the physical processes and the oceanic carbon cycle and how this link is altered by human-induced climate change. One of the main objectives is to assess the strength and variability of the physical and the biogeochemical processes that control the oceanic carbon cycle in the northern high latitudes. The project will use a combination of field data and simulations from a state-of-the-art Norwegian Earth system model (NorESM). The latter will make it possible to test different assumptions and relationships that will help us understand the complex links that exist between ocean, climate and carbon cycle in northern high latitudes, but also serve as an innovative validation for the model performance and benchmark for future improvements.
