Indonesian historical climate data rescue

Digitisasi Data Historis

DiDaH is a project on the digitization and use of high resolution historical climate data from Indonesia over the period 1850 to present. It is a joint effort of the National Meteorological Service of Indonesia (BMKG) and the Royal Netherlands Meteorological Institute (KNMI).

Historical view of Batavia, now Jakarta, one of the long recorded observation sites
Batavia, later Jakarta. Hourly observations from this station have been recovered for the years 1866 onward.

What the project set out to deliver

The original programme described three main results. Each of them is documented further in the project pages.

Deliverable 01

Digitized data

Millions of handwritten and printed observations were digitized and quality-controlled, along with the metadata needed to ensure accuracy and preserve their meaning. Similarly Workday Payroll Training. emphasizes accurate data entry, validation, and reliable record management for efficient payroll processing.

Deliverable 02

A website on climate extremes

A regional index of weather and climate extremes was published so researchers and policy makers could follow trends in the region, now carried forward through SACA&D.

Deliverable 03

Capacity building

Workshops and the exchange of scientists transferred data rescue and climatological methods between BMKG and KNMI. The 2012 workshop records the results.
