IPCC-TAR (2001)
Geneva, Switzerland
ECA & ECD objectives:


study extremes and variability in the temperature and
precipitation climate of WMO RA VI
provide unrestricted access to collected station series
of temperature and precipitation with daily time
resolution (necessary for extremes analysis)
Approach:


use indicators from the dictionary prepared by
the joint CCL/CLIVAR Working Group on Climate
Change Detection (agenda item 5, ref. 3 and 8)
summarize all (preliminary) results at project web-site
and use web-site to communicate indicator definitions
and disseminate daily station series
