Combining Data Assimilation and Machine Learning to emulate a numerical model from noisy and sparse observations

Speaker: 
Julien Brajard (Data Assimilation)
Seminar Date: 
12. February 2019 - 11:15 - 11:45

Is it possible to emulate a numerical model from noisy and sparse observations? How realistic and skillful can it be?

Warmer urban climate in Arctic cities, By: Igor Esau, Victoria Miles and the HIARC project team

Speaker: 
Igor Esau (Climate Dynamics and Prediction)
Seminar Date: 
22. January 2019 - 11:15 - 11:45

The recent IPCC special report on 1.5C warming target has envisioned a number of detrimental effects and environmental challenges that will emerge with the global warming in excess of the target. Our study reveals that majority of the Arctic population is already leaving in the climate conditions significantly warmer than 1.5C and even 3.0C above the mean XXth century regional temperature. These urban temperature anomalies, known to as the urban heat islands (UHIs), may help us to study the effects of the warmer climate in the Arctic region.

Two-way nesting in coupled atmosphere-ocean modelling

Speaker: 
Prof. (emeritus) Dr. Lars Petter Røed
Seminar Date: 
17. January 2019 - 12:30 - 13:30

Nansen Lecture based on Røed's recently published book by Springer titled: “Atmosphere and Ocean on Computers”.

Applications of operational oceanography product to fisheries management and operation

Speaker: 
Dr. Hiromichi Igarashi
Affiliation: 
JAMSTEC, Yokohama, Japan
Seminar Date: 
3. December 2018 - 12:30 - 13:10

Operational oceanography products, reanalysis, NRT analysis and forecast ocean state, can provide us a variety of value-added information useful for fishery stock management, monitoring and efficient fishery operation. In this talk, applications of the operational products to the operational fisheries in the North Pacific conducted by JAMSTEC data synthesis research group will be presented.

A Nested-Grid Snow Modeling System

Speaker: 
Dr. Glen E. Liston
Affiliation: 
Colorado State University
Seminar Date: 
14. November 2018 - 11:00 - 12:45

Over the last 35 years, Dr. Liston has developed a snow-evolution modeling system (MicroMet, SnowModel, and SnowAssim) that can be used for a wide range of snow and other cold-season, cold-region applications. The model formulation is general enough to allow simulations over temporal domains spanning days to decades, and spatial domains spanning from local measurement sites to pan-Arctic regions at spatial resolutions ranging from 1-m to 10-km.

Dynamical downscaling of CMIP5 for future projection of the North Pacific Ocean state

Speaker: 
Tsuyoshi Wakamatsu (Ocean Modeling)
Seminar Date: 
6. November 2018 - 11:15 - 11:45

The North Pacific Ocean (NPO) state is about to experience significant transition by the end of this century under the current trend of the global climate change. NPO coastal communities are now facing a challenge to establish adaptation plans to mitigate impacts of the climate change to their socio-economical environment. The best resource to provide the future projection of an ocean state available today is CMIP5 data and they have been used substantially for evaluating future coastal marine environment.

CIMR: the Passive Microwave Satellite Mission for Copernicus.

Speaker: 
Thomas Lavergne,
Affiliation: 
MET Norway
Seminar Date: 
31. October 2018 - 12:30 - 13:10

EU is currently planning the future of its fleet of Earth Observation missions: the Sentinels. To serve the EU integrated Arctic policy from 2025, several candidate missions are under study. One of the candidate, the Copernicus Imaging Microwave Radiometer (CIMR) is an advanced Passive Microwave Radiometer mission, improving on the now 40 years capability of SMMR, SSM/I(S), and AMSRs. The two primary objectives of CIMR are all-weather, high-resolution, high-accuracy, sub-daily observations of sea-ice concentration (SIC), and sea-surface temperature (SST).

Responsible Research and Innovation - why should we start thinking about it?

Speaker: 
Dorothy Dankel
Affiliation: 
University of Bergen
Seminar Date: 
23. October 2018 - 12:30 - 13:30

This 2-part presentation starts with an easy intro to Responsible Research and Innovation (RRI) and putting RRI in the context of NFR and Horizon2020 proposal writing (30 min) followed by discussion Q/A and RRI exercises for moe in-depth exposure.

Syntool - a tool for data browsing and visualisation

Speaker: 
Tor I. Olaussen
Seminar Date: 
23. October 2018 - 11:15 - 11:45

The Syntool Arctic Portal, in short, is a satellite remote sensing visualization, comparison tool and data browser. A multitude of remote sensing data products can be imported to individual layers in Syntool. These layers can be turned on and off, making it possible to compare disparate datasets both spatially and temporally.

Crossing the Southern Ocean: How the parameterization of poleward heat transport may differ from that of the real world

Speaker: 
Matthew Hecht
Affiliation: 
LANL, USA
Seminar Date: 
22. October 2018 - 12:30 - 13:10

As the only major ocean basin that allows for circumpolar flow, with no continental boundaries against which zonal pressure gradients may be established, the Southern Ocean has been singled out as a region in which transient mesoscale eddies are especially important. When effects of bathymetry on the flow are considered, however, transient eddies alone need not generate the entire poleward heat transport that compensates the equatorward heat transport forced by the prevailing westerly winds.
