Dissemination of scientific output and data stewardship.

We will strive to maintain our reputation for publishing highly-respected work in high quality and high impact factor journals. At a more widely accessible level, we will ensure that current scientific perspectives are highlighted on our web-based set of climate information sheets (http://www.cru.uea.ac.uk/cru/info/). These are targeted for non-experts, and currently receive about 3000 independent visitors per month – a highly efficient method of outreach to a broad range of scientists, media and members of the public. New climate reconstructions based on improved proxy data sets and improved reconstruction methods will be made available to other RCC projects during the project and made publicly available at the end of the project. There is currently no NERC designated data centre with a strong remit for climate proxy records, but our climate reconstructions would be provided to the British Atmospheric Data Centre if appropriate, and would certainly be lodged with the World Data Centre for Paleoclimatology (hosted by the US National Geophysical/Climatic Data Center) and will also be disseminated via the Climatic Research Unit’s own website, which has a permanent and well-publicised section for the distribution of data sets.
