Participants and data

	Today, SACA&D is receiving data from 11 participants for 15 countries and the SACA dataset contains 11521 series of observations for 9 elements at 9711 meteorological stations throughout Southeast Asia. 17% 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 gridded dataset

	SA-OBS version 2.0 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 2017-12-31. 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 ).
