Climate System Modelling

Climate models help us to gain information on the climate system and estimate how the climate will change in the future. In climate model simulations, anthropogenic and natural forcings as well as feedback phenomena are taken into account and their impact on the climate is evaluated. The results can be used when deciding about methods of mitigating and adapting to climate change.

The Climate System Modelling group studies the physical and chemical processes, interactions and feedbacks of the climate system. Atmospheric aerosols, radiation, clouds, snow and interactions between atmosphere, land and oceans are the main research subjects. The group develops and uses a wide range of different models including process-level, large-eddy simulation, Earth system, regional climate and integrated assessment models. Group’s climate simulations are also used to support regional and global adaptation and impact studies of climate change. One of the strategically prominent tasks of the group is to co-operate with the atmospheric sciences center INAR (Institute for atmospheric and Earth system research) in the field of global modelling.

Projects

 OceanNETs: Ocean-based negative emission technologies impacts and possibilities are explored using Earth System Model simulations. The CO2 concentration is reduced by directly removing it from sea surface or by increasing alkalinity of the surface ocean. 

CRiceS: The EU H2020 project CRiceS focuses on improving model predictions of the role of polar processes in the climate system that consists of the oceans, ice and snow cover, and the atmosphere. The project is coordinated by FMI. 

FORCeS: The H2020 project FORCeS aims to understand and reduce the long-standing uncertainty in anthropogenic aerosol radiative forcing, allowing to increase confidence in climate projections. 

FOCI:The HORIZON project FOCI aims to assess the impact of key radiative forcers, the processes of their impact on the climate system.  Implement these into global Earth System Models and into Regional Climate Models, and  to investigate mitigation and/or adaptation policies incorporated in selected scenarios of future development. 

MOAC: Marine organic aerosol and its impacts on clouds and climate. In this project we use modelling tools like large eddy simulator UCLALES-SALSA to assess the impact of marine organic aerosol on shallow boundary layer clouds. Eventually this project aims at reducing large uncertainties related to the climate effects of marine aerosols and their impacts on clouds. 

NETS: Designing robust mitigation scenarios that hedge against the uncertainties of the Earth system and negative emission technologies. The project combines integrated assessment modelling with probabilistic Earth system modelling.  

OptiMit: Examining how the optimal role of global forests in climate change mitigation depends on and interacts with the development of CO2 removal technology. 

ClimComp: The project examines what are the competencies needed in the society to efficiently mitigate and adapt to climate change and how these competencies are learned and taught throughout the education system. Our group specifically develops data and code platforms for easier access to climate data. 

SuCCESs: The SuCCESs project analysesthe key interdependencies between energy, land-use and materials systems for climate change mitigation. We develop a novel integrated assessment mode (SuCCESs IAM) and use it to calculate long-term mitigation scenarios that achieve the Paris Agreement climate targets within the energy-land-materials system. 

Magica:Tenhances knowledge exchange from climate research to societies to support policy-making and climate actions across Europe. Among its outreach and engagement activities, MAGICA will stage key European climate events including ECCA (European Climate Change Adaption) Conferences in 2023 and 2025, Climate Neutrality Forum, Sea Level Rise Conference, and a special session at EGU2023.

In our groups work we use and develop many tools and models, which have been shortly described here.

Research tools

EC-Earth: A European Community Earth System Model is a comprehensive model developed in collaboration with 30 institutes in 12 European countries. It can be used to study the effects of climate change in land, atmosphere and ocean as well as the connections between the different components of the Earth system.

TM5: Transport Model 5, a chemistry transport model, which simulates the evolution of aerosols and trace gases in the atmosphere. It is the aerosol-chemistry component of EC-Earth 3.   

LPJ-GUESS: A process-based dynamic global vegetation-terrestrial ecosystem model (DGVM) designed for regional and global studies. It simulates dynamics and composition of vegetation in response to changes in climate, land-use change, atmospheric CO2, and nitrogen.

(Open)IFS: Atmospheric model developed at the European Centre for Medium range Weather Forecasts. Model is used within EC-Earth Earth system model as well as standalone model. Aerosol module development is ongoing in the group for the mode.

NEMO: Nucleus for European modelling of the Oceans: Global ocean model used in the EC-Earth Earth system model.

PISCES: Biogeochemistry model for the ocean.

NorESM: Norwegian Earth System Model, developed in Norway with most parts of the model based on the Community Climate System Model developed by the National Center for Atmospheric Research (NCAR) in the USA. Like EC-Earth, NorESM is a comprehensive climate model that can be used to study various topics related to climate and climate change.

UCLALES-SALSA: a large eddy simulator coupled with detailed aerosol-cloud microphysics module SALSA. The large eddy simulator predicts turbulent atmospheric flow fields that carry heat, moisture and aerosol particles and cloud droplets. Turbulent updrafts are needed to produce high humidities that produce and maintain shallow clouds. The SALSA module simulates cloud formation and processes related to precipitation and cloud droplet freezing, which have an impact on cloud stability.

Harmonie Clim: 

SCORE:  An integrated assessment model (IAM) based on marginal abatement cost (MAC) curves and a simplified climate model, including a stochastic programming approach for uncertainty and learning for selected parameters. The model has been used particularly to assess mitigation strategies under uncertainty and learning regarding climate sensitivity.

SuCCESs: A global integrated assessment model (IAM) developed at FMI for assessing the interactions between energy, land, material and climate systems. We use the model for analyzing optimal climate change mitigation strategies in long-term scenarios, focusing particularly on the synergies and trade-offs between actions in energy, land-use and material production.

University of Victoria Earth System Climate Model (UVic ESCM): An Earth system model of intermediate complexity that allows a wider range of scenarios or uncertain parameters to be explored compared to comprehensive Earth system models. It consists of a 3D Ocean model, full carbon cycle, and 2D energy-moisture balance model to represent the atmosphere.
