1. Page 1 Quick Update on the ESA “Climate Change Initiative” (CCI) PP Mathieu, ESA EO Science & Exploitation WOAP – Hamburg – 29-31 March 2010

2. Page 2 CCI Rationale & Objective The objective of Climate Change Initiative is to realize the full potential of the long-term global Earth Observation archives that ESA together with its Member states have established over the last thirty years, as a significant and timely contribution to the ECV databases required by UNFCCC. It will ensure that full capital is derived from ongoing and planned ESA missions for climate purposes, including ERS, Envisat, the Earth Explorer missions, relevant ESA-managed archives of Third-Party Mission data and, in due course, the GMES Space Component. CCI Programme following Ministerial Council in 2008, about 75MEUR over 6 years for about 20 ECVs Starting NOW
