The Climate Indices for Pacific Sectoral Applications (CIPSA) Portal formerly known as the Pacific Climate Change Data Portal provides site-specific historical climate information and trends in mean and extreme climate indices. Current support, including enhancements delivered in 2025, are provided through the third phase of the Climate and Ocean Support Program in the Pacific (COSPPac), funded by the Australian and New Zealand Governments. The portal was originally developed in 2009 with funding from Australian Aid through the Pacific Climate Change Science and Pacific-Australia Climate Change Science and Adaptation Planning Programs. Its design is modelled on a similar tool developed for Australia. The climate extremes indices are calculated using Climpact, associated with the WMO Expert Team on Climate Services Information Systems for Decision Support. The portal also forms part of the Bureau of Meteorology’s contribution to the WMO RA-V Pacific Regional Climate Centre Network, as a Consortium member for the Node on Climate Monitoring.
