Fredrik Boberg, DMI: boberg

“I have analysed and validated several ensembles of climate model data, including CMIP5 and CORDEX. The ensembles have been compared with gridded observations using e.g. probability density functions. Furthermore I have run the regional climate model HIRHAM, using the CMIP5 model EC-EARTH (and in some extent NorESM) at the boundaries, for a number of regions, including a number of 5km resolution Greenland runs and  also a number of 50km resolution Arctic domain runs. The emissions scenarios under investigation are RCP4.5 and RCP8.5.”

Dean Chen, UHEL:DeanChen

Dean Chen, started his PhD in the modelling group in November 2017 with the topic “Aerosols-formation, growth, transformation and a study on its anthropogenic versus biogenic precursor”. He will apply different models to study the formation of secondary organic aerosols (SOA) at the SMEAR II in Hyytiälä and the SORPES station in Nanjing, China.At the eSTICC project, his main task is comparing the aerosol module of ECHAM-HAM with the 0-D Model Malte-Box.

Tanja Dallafior, SU:Tanja

“My main interest is the role of man-made aerosol particles and how they affect Arctic climate. Also, I intend to evaluate the general circulation model NorESM for the Arctic region using the growing body of observational data available.”

Eyal Freud, SU: EyalFreud

“The focus of my recent research activities was on characterising the properties of the long-term observations of aerosol number distributions and transport patterns in a pan-Arctic perspective. Among other things, this helps evaluating of how well general circulation and chemical transport models capture the spatial and temporal variations of the Arctic aerosol, which in turn are strongly linked with the cloud properties and their effect on the changing Arctic environment.”

“My work includes simulating stratospheric aerosol, especially solar radiation management model experiments. I also work on the development and implementation of the aerosol models in global scale aerosol-climate models (ECHAM-HAMMOZ & EC-Earth).”

Efrén Lopez Blanco, AU: efren

“I do have a particular fascination for the interrelation of different environmental processes in both space and time, allowing feedback loop effects without clear and visible consequences. For me, it is this fact that makes environmental modelling both so challenging and exciting. For that reason, I am very enthusiastic about the proposed research at both Aarhus and Edinburgh University with regards Ecosystem-Atmosphere interactions in Arctic Catchments. The main goal is to use model-data fusion approaches to analyze the patterns of carbon and energy exchanges and their links to biological processes in Greenland. The research focuses on how these items are influenced by climate, vegetation dynamics, soil properties and hydrology, studied in detail both from a measurement and a modelling perspective. In order to do so, the following sub-projects will be assessed: (I) Inter-annual variability analysis of time-series data collected at catchment scale (Nuuk, Greenland); (II) Inter-annual variability modelling (using SPA model) of time-series data collected at catchment scale and (III) dynamic carbon exchange modelling (using ACM model) at coarser spatial resolution.”

Marianne Sloth Madsen, DMI:Madsen

“I work on improving the representation of the Greenland ice sheet in the EC-Earth global climate model. As part of this, EC-Earth has been coupled to the PISM ice sheet model to include ice dynamical processes e.g. calving and topography changes.  A new surface parameterization has been included for ice sheets, and a new snow albedo parameterization that includes albedo changes in response to melting and refreezing in the snow pack is being implemented. The EC-Earth-PISM coupled model will be used to investigate the role of ice sheets in a changing climate.”

Shabbaz Memon, University of Iceland: memon

“I work on the scientific workflows which are provided by eSTICC. Scientific workflows allow to automate coupling of tools in a very flexible way, thus eliminating manual steps or shell scripts consisting of hundreds of lines and hardcoded paths and configurations which are not easy to adjust to new environments such as new High-Performance Computing clusters.”

Joonas Merikanto, FMI: joonas_selfie

“I work in atmospheric nucleation theory and global atmospheric modelling. At the moment I am developing a new representation of neutral and ion-induced sulfuric acid nucleation to be used in global models. I am also working on an aqueous phase secondary organic aerosol description to be used in ECHAM6-SALSA climate model.”

Norbert Pirk, LU: Norbert

“I am a PhD student in Arctic biogeochemistry at Lund University with a particular interest in the measurement of greenhouse gas exchange from Arctic tundra ecosystems. The measurement sites of my project are located on Svalbard and Greenland, and feature both seasonal and year-round installations. One of the main objectives of my work is to measure during the long and harsh Arctic winters, and thereby improve our understanding of the processes behind the observed greenhouse gas exchange.”

Narges Rastak, SU: NargesRastak

“I am interested in the interactions between atmospheric water vapor and aerosol particles, as well as how these interactions influence the ways that aerosol particles influence the Arctic climate. In eSTICC I work towards implementing and testing state-of-the-art parameterizations of aerosol-water interactions in Earth System Models such as NorESM.”

Anton Rusanen, UHEL: AntonRusanen

“I am working on documenting and improving the data processing of the SMEAR measurement stations. I am also interested in the applications of machine learning methods in atmospheric sciences.”

 Tian Tian, DMI:AntonRusanen

“I am interested in the atmosphere-ocean-ice interactions in the coupled climate system on various space and time scales. I am currently working on improving the description of the Atlantic meridional overturning circulation (AMOC) in the EC-Earth global climate model. Special attention is given to the effect of high-latitude salinity structures and linkages between the arctic sea-ice export and AMOC. I am testing several surface nudging techniques in reconstructing the variability of the AMOC, which is thought as a crucial component of the north Atlantic climate. The sensitivity experiments will be used to evaluate the impact of the AMOC on the decadal predictability of the Arctic surface temperature and sea ice variation. ”

“As a part of WP2, my research focuses on methane emission estimates in high northern latitudes and their contributions to recent year changes in the global atmospheric methane concentrations. CarbonTracker Europe-CH4 inverse model will be further developed to improve the emission estimates by expanding atmospheric methane concentration observation network from Finland, Sweden, Norway and Russia.”

Filippo Xausa, UHEL: filippo

“I’m working with the global aerosol-climate ECHAM-HAM. My work consists of developing new emission modules, model evaluation, and model application to various natural and anthropogenic scenarios. In more detail, I focus on the modeling of submicron particle number and cloud condensation nuclei concentrations derived from anthropogenic sources.”
