1st ACRE Workshop: Reanalyses Data, Historical Reanalyses & Climate Applications

MeteoSwiss, Zurich, Switzerland, 23-25 June 2008

The aim of the workshop was to mirror the ACRE initiative, by bring together researchers recovering, imaging, digitising and archiving historical data for reanalyses, together with developers of various reanalyses and those from the climate applications and impacts communities who have an interest in using reanalysis products. It was hoped that in such an assembly, participants would be able to gain a better appreciation of each others efforts and needs so that a firmer basis for collaboration and cooperation could be forged, with users being primed in terms of their expectations of, and feedback on, the range of products that will flow from the first release of the full 20th Century Reanalysis Project (1892-2008) early in 2009.

This is planned to be the first of several major workshops bringing together those involved in the full range of activities under the ACRE initiative. As a result of this first workshop, and the creation of four working groups (detailed in the body of the text) within ACRE, there will now be scope for more specific working group meetings.
