International Collaboration on Data Assimilation in Terrestrial Carbon Cycle Science
The objective of Carbon Fusion is to bring together researchers to determine how data assimilation can generate improved insights into the processes underlying the terrestrial C cycle, and thence enhance our prognostic capabilities.
Our particular objectives are to:
- form working links with world-class researchers, in order to accelerate the development of DA in terrestrial C cycle science;
- bring UK strengths in terrestrial C cycle science (CTCD) and data assimilation (DARC) to the international research community, while benefiting as much as possible from international approaches to the problem;
- develop collaborations that will enhance relevant research capabilities;
- develop a global vision and strategy for research.

Visitors
Cory Pettijohn, a post-doc in Bev Law's lab at Oregon State University visited Edinburgh in August 09. Cory worked on linking the US CLM land surface model into the EnKF data assimilation scheme. Cory's particular focus was on assimilating hydrological and water flux observations.
Fabricio Brito, a PhD student with Yoiso Shimabukuro, at INPE, Brazil, visited Edinburgh in October 09. Fabricio worked on assimilating carbon flux and stocks data from a variety of Amazonian sites into the DALEC model using the EnKF.

Workshops and reports
FLUXNET workshop: CarbonFusion was a sponsor of the FLUXNET Asilomar Modelling Workshop, California, 11-13 February 2009. For more details and workshop presentations,click here
CarbonFusion, working with the UK National Centre for Earth Observation, has produced a working note (click here) for a UK research programme exploiting carbon dioxide measurements from the NASA Orbiting Carbon Conservatory (OCO) and the JAXA Greenhouse gas Observing SATellite (GOSAT)The meeting report for the CarbonFusion Land Surface Modelling/FLUXNET meeting has been published in FLUXLETTER (Vol. 1 No. 4) and is available here.
The first Carbon Fusion report, detailing progress since the International Workshop, is available as a PDF here.
The Carbon Fusion international meeting, Edinburgh, 9-11 May, 2006
Research seminars and posters from the meeting can be accessed here.
Carbon Fusion is a collaborating programme with the Global Carbon Project.
Carbon Fusion is funded by the UK Natural Environment Research Council (NERC), and led by two of NERC's Collaborative Centres of Excellence - the Centre for Terrestrial Carbon Dynamics (CTCD) and the Data Assimilation Research Centre (DARC). Other partners include the Climate and Land-Surface Systems Interactions Centre (CLASSIC), and the NERC QUEST programme (Quantifying and Understanding the Earth System).
Carbon Fusion coordinators: Mathew Williams (mat.williams@ed.ac.uk), School of GeoSciences and CTCD, University of Edinburgh; and Shaun Quegan (S.Quegan@sheffield.ac.uk), CTCD, University of Sheffield.
