Participants and data

Today, SACA&D is receiving data from 23 participants for 15 countries and the SACA dataset contains 5979 series of observations for 10 elements at 3864 meteorological stations throughout Southeast Asia. 33% of these series is public, which means downloadable from this website for non-commercial research (see Daily data > Data dictionary for an overview of all available series). Participation to SACA&D is open to anyone maintaining daily station data. If you want to join please contact us. See our Data Policy for more details.

SA-OBS version 1.0 has been released. SA-OBS is a daily gridded observational dataset for precipitation and temperature in Southeast Asia based on SACA&D information. The full dataset covers the period 1981-01-01 until 2014-12-31. It has originally been developed and updated as parts of the Joint Cooperation Program project.



DiDaH project

SACA&D is developed as part of the Digitisasi Data Historis (Didah) project. This project is focusing on the digitization and use of high-resolution historical climate data from Indonesia and other Southeast Asian countries. Didah is a joint project between the National Meteorological Services of Indonesia (BMKG) and the Netherlands (KNMI).

The results on this website contribute to the work of the Asian Pacific Network for climate extremes (APN).
