9. Project structure (A)An international workshop in the framework of the World Meteorological Organization’s “DARE” (DAta REscue) and “Climate Extremes” programs. To be held in the second half of 2009 in Indonesia. (B)Digitization of historical data from Indonesia at BMKG. Starting January 2010 and taking two years, until fall 2011. (C)Exchange of experts between KNMI and BMKG. (D)A five day regional Indonesian workshop by the finishing of the project, to be expected in the second half of 2011, to advertise the results and explore regional applications in development. 2.

27. Developments and plans 1.Japan ( Tokyo Metropolitan University) is currently digitizing 1901- 1916 daily precipitation 2.(1) will probably be followed by 1917-1957 monthly precipitation 3.KNMI will request BMKG to make an inventory of their digital and hardcopy climate data 4.When the inventory is available, KNMI en BMGK will fine-tune the current project proposal 4.Current developments and plans
