21st Century Challenges in Regional Climate Modelling

3rd Lund Regional-scale Climate Modelling Workshop
21st Century Challenges in Regional Climate Modelling
Lund, Sweden, 16 – 19 June 2014

Scope

The workshop is a follow-up to the regional climate modelling workshops held in Lund, Sweden in 2004 and 2009. Research on regional climate modelling has remarkably expanded during the last few years. The aim of the Workshop is to review the overall and specific developments and progress in regional climate modelling over the last five years, to discuss pertinent open issues and challenges, and to provide input for new developments on the field. The meeting will cover a wide range of regional climate related topics, from basic modelling research on numerics, resolution and parameterisation to model evaluation and relevant observations, ensembles and applications. The workshop will also provide opportunities for working meetings for networks and projects. The workshop is jointly organised by Lund University, SMHI, DMI, HZG and the International Baltic Earth Secretariat.

Invited and contributed papers will be presented in plenary complimented by extended poster sessions. Workshop language will be English. Continue reading

Workshop on Model-Data Fusion for Carbon Cycle Studies

Model-Data Fusion for Carbon Cycle Studies
International seminar
18 February 2014, Lund University, Lund, Sweden

The past decade has seen a proliferation and expansion in the availability of observational
datasets and proxies relevant for characterising temporal and spatial variations in the carbon cycle from regional to global scales. Process-based models of the carbon cycle have also evolved and representations of the carbon cycling and associated feedbacks are now included as standard components in climate (Earth system) models. Despite this, future climate studies with Earth system and offline carbon cycle models reveal that much uncertainty remains as to the trajectories and geographic patterns of change in carbon stocks and fluxes in a future, high-CO2 world. Approaches for inferring carbon balance that bring together process-based models, observational data such as ecosystem fluxes and remote-sensing products, and advanced statistical techniques offer promise for informing and constraining ecosystem and Earth system models, and reducing uncertainty as to future changes. These approaches rely on elaborated escience
infrastructures, in particular high performance computing systems and efficient data
handling.

This seminar will gather leading experts in model-data fusion approaches for studies of the carbon cycle in the atmosphere, oceans and on land as the basis for a broad discussion of the above topic. The seminar is hosted by the Foundation for Strategic Environmental Research research programme Mistra-SWECIA and the Lund University Strategic Research Areas Biodiversity and Ecosystem Services in a Changing Climate (BECC) and Modelling the Regional and Global Earth System (MERGE) as well as the strategic collaborative research programme in e-science eSSENCE.

eSSENCE Academy Workshop 2013, October 16-17, Lund

The eSSENCE Management has the pleasure of inviting all of the eSSENCE community to the 2nd eSSENCE Academy Workshop. The strategic research programme is in its fourth year of developing state-of-the-art e-Science for the benefit of society in a collaborative effort between our three universities. Now we will have the opportunity to meet and acquaint ourselves with the exciting research that is happening within eSSENCE.

There will be no attendance fees for these event. Programme, how to register, and more information will follow after Summer.

Enjoy the bright long days and return refreshed in Fall.

“En vänlig grönskas rika dräkt
har smyckat dal och ängar.
Nu smeker vindens ljumma fläkt
de fagra örtesängar.”

Best regards for a pleasant Summer,

Coordinator of eSSENCE

20 million to Cloud Computing

Erik Elmroth at umeå University

Energy-efficient computer resources which adapt its capacity to the needs of the application. This is the objective of the project “Cloud Control” which was recently awarded 20 million SEK from the Swedish Research Council. A group of researchers from Umeå and Lund under the leadership of professor Erik Elmroth from the Department of Computer Science at Umeå University, will develop methods and tools to handle resources and services in future computer centers with distributed systems of virtual machines.
The main goals of the project are:

  • to optimize the usage of servers
  • to predict the usage peaks for specific applications so that the number of virtual machines that are needed can adapt in time
  • to optimize the physical placement of the servers in order to reduce cooling requirements

The project will receive funding during five years.
