tambora.org is a collaborative research environment for climate and environmental history. It is open to anyone interested in reconstructing the following from any kind of man-made source (i.e. chronicles, flood marks, logbooks…):

  • weather and climate
  • geophysical, astronomical and other environmental events
  • impact on and coping strategies of societies
The main focus of tambora.org is Historical Climatology. Years of meticulous work in this field in research groups around the world have resulted in large data collections on climatic parameters such as temperature, precipitation, storms, floods, etc. with different regional, temporal and thematic foci.

tambora.org enables researchers to collaboratively interpret the information derived from historical sources. It provides a database for original text quotations together with bibliographic references and the extracted places, dates and coded climate and environmental information.

The system allows for the integration and sustainable storage of existing data collections, as well as the entry of new data. tambora.org already contains two large data collections (HISKLID and parts of Weikinn) and several smaller data collections, and is continuously growing. Everyone is invited to add further data sets.

Additionally, tambora.org provides a growing toolbox for creating and presenting these kinds of data.

To acknowledge scientific work, tambora.org facilitates the process of assigning citable DOIs (digital object identifiers) to integrated data collections by providing the necessary infrastructure and institutional responsibility for quality control.

If you have any questions regarding the project, please send an email to Prof. Dr. Rüdiger Glaser or Michael Kahle.
