First Service Date ECMWF – October 2006 NCAR – October 2006 CMA – June 2007
Table 1: Summary of TIGGE archive activities at ECMWF (EC), NCAR, and CMA. Register users are all persons who agreed to usage conditions (education and research), active users are users with access patterns that indicate probable research activities, data processed is the data volume processed to create user subsets, and data delivered data volume delivered to the users. 2006 1 = 10/06 - 12/06, TIGGE Archives began in October 2006 2008 2 = 01/01/08 to 09/30/08 NCAR 3 = Users that have download some data. Total registrations = 142 EC 4 = Users that have download some data EC 5 = Users that have download some data three or more times CMA 6 = At CMA 40 Terabytes (TB) were processed to provide 10 TB for research at CMA. 8-10 GB/day were also provided for the Beijing Olympic Games
