Improved quantification of global carbon cycle fluxes
Last updated 2 May 2003

3-6 June 2003

Venue and date

The meeting will take place between 3-6 June 2003 at the Marriott Hotel, Sheffield, UK.

Goals of meeting

International workshop on improved quantification of global carbon cycle fluxes organized by the Terrestrial Carbon Observation (TCO) initiative and the Global Carbon Project (GCP).

The jointly organized workshop is intended to increase the availability of more accurate and mutually consistent estimates of the distribution of C sources and sinks at a regional and global level. This goal can be achieved by convergence of in situ and satellite observations, experiments and modelling strategies; improvements in data acquisition and sharing; and product generation, distribution and use. The workshop will focus on the following questions and associated issues:

1. What carbon cycle data products could be routinely produced from a carbon observation system based on model-data and model-data fusion?

2. What are the main conceptual approaches to assimilating atmospheric C content, terrestrial carbon flux and remotely sensed data into coupled atmospheric circulation-carbon cycle models?

3. What is the present and eventual uncertainty regarding the main C fluxes at global and regional scale, and how will it be reduced by projects currently underway and about to begin?

4. In what regions, and on what topics, will new data inputs make the largest contribution to reducing the residual uncertainties? What actions should be taken to overcome the gaps and limitations identified?

The above questions will be tackled in working sessions by participating scientists who come from key existing and proposed regional and global projects; those leading the preparation and assembly of critical data sets (major modelling groups active in regional and global projects) and representatives of enabling agencies.

The workshop is sponsored jointly by the TCO/GTOS and GCP. The intended outputs include peer reviewed publications, established priorities for observations and model-data products, and policy-oriented summaries and implications for research and observations.

There is no international airport at Sheffield. The most convenient airports are Manchester (easiest), Birmingham (slightly longer train ride) and East Midlands (not far, but has bad public transport so you would require a taxi).

The following transport options are available from the airports to the hotel:

Manchester Airport to Sheffield
Taxi: £46 (approx 1 hour, allow 1.5)
Train: £14.95 single, £18.60 return

East Midlands Airport to Sheffield
Taxi: £44 (approx 1 hour, allow 1.5)
Public transport not really a viable option

Sheffield train station to Hotel
Taxi: £3.50-£4.00
Public transport: not possible as there are no bus stops close to the hotel

Route from Airport to hotel

Hotel Arrangements

The workshop will be held at the Marriott Hotel, Kenwood Road, Sheffield S7 1NQ
United Kingdom, Phone: 44 114-258-3811, Fax: 44 114-255-4744. The Hotel is set in 12 acres of parkland and is only 3 miles from the city centre. The Hotel offers a range of conferencing facilities fully supported by the Marriott Meeting Edge standard.


A conference dinner will be held at Hassop Hall.


During June the weather in Sheffield is mild with an average temperature of 16 degrees Celsius and an average precipitation of 50mm. Up to date information

Exchange rates

Current exchange rates are approximately 1 Euro = 1.10 USD = 0.69 GBP (United Kingdom Pounds). The most up-to-date exchange rate can be obtained from the following site: http://www.xe.com/ucc/. It is possible to exchange money at exchange offices which are located at the airport, train stations and the city center. Money can also be withdrawn from cash machines using a credit card (usually the best exchange rate).
