Workshop: Pathway to regular and sustained delivery of climate forcing datasets
On this page:
28 October @ 13:00 – 31 October @ 13:00 GMT
Context
In discussions around a potential sustained mode or “operational” CMIP activity, provision of climate forcing datasets has been identified as high priority for moving to a regular delivery mode to meet user needs and sustained by appropriate funding, resources and infrastructure. Indeed, one of the CMIP Climate Forcing Task Team core goals is to “Work with teams to identify, develop, document and deliver an updated and expanded forcing collection to near real time”. There is strong agreement around this ambition; however, the reality of implementation is complex and the funding landscape remains fragmented. In addition, we recognize that the very development of climate forcing datasets has a foot in basic research developing the knowledge of historical evolution of forcing agents, and quantifying their uncertainties, which has to occur in parallel to their “operational” use – both need to be sustained and augmented if the ambition is to be realized.
This four day workshop will be an opportunity to review the current provision model, discuss the key challenges, hear from users and potential users of the data, co-create a range of practical implementation options, develop the vision and generate concrete actions towards regular and sustained climate forcings dataset delivery. The outcomes of the workshop will feed into the CMIP sustained mode scoping study being led by Helene Hewitt (CMIP Panel Co-chair) and Greg Flato (WGCM Co-chair).
