Background and framework
The Vice Minister for Transport, Public Works and Water management, Mrs. J.C. Huizinga - Heringa visited Indonesia in January 2009. During this visit she discussed among others water management and climate change with BMKG, the National Meteorological Service of Indonesia. During these talks, Mrs. Huizinga agreed to support a new cooperation project between BMKG and KNMI to digitize and make available for research, historical climate data from the Indonesian region.
In the framework of this project Didah, which officially started on the 10th of July 2009 and will last until December 2011, BMKG and KNMI will digitize millions of handwritten and printed historical weather and climate observations from the period 1850 present. Especially in view of the global warming issue, this new and additional information on the Indonesian climate will be invaluable for climate researchers and others in the region who depend on a better understanding of climate and weather extremes.
The Didah project will not only produce newly digitized historical climate data. BMKG will archive and process the data and produce climate information e.g. on trends, patterns and extreme weather events. BMKG will adopt state of the art database techniques and climatological methods and tools that were developed at KNMI to establish a web-based climate (change) information system for the Indonesian region. To realize this, BMKG specialists will visit and work at KNMI for several months during 2010 and 2011.
In the framework of project Didah an international
climatological workshop was held in Jakarta in December 2009. Under auspices of
the World Meteorological Organization (WMO) several international data rescue
and climatology experts presented lectures and training and held discussions with
trainees from BMKG and stakeholders from the region.
