Sea surface temperature monitor and predict the El Niño phenomenon. Weather satellites have been available to determine sea surface temperature information since 1967, with the first global composites created during 1970. Since 1982, satellites have been increasingly utilized to measure SST and have allowed its spatial and temporal variation to be viewed more fully. Satellite measurements of SST are in reasonable agreement with in situ temperature measurements. The satellite measurement is made by sensing the ocean radiation in two or more wavelengths within the infrared part of the electromagnetic spectrum or other parts of the spectrum which can then be empirically related to
Central Weather Bureau sea for shipping, fisheries, tourism and other interested parties. Variables including wave height, tides, sea level variations, sea surface temperature, and ocean currents are measured to provide an accurate picture of current conditions. The center is also responsible for informing the public of tide times, and cooperates with local tourism bureaux and Fishermen's Associations to erect electronic billboards in harbours to inform seafarers of ocean conditions. The Bureau also includes the following departments: The CWB building is accessible within walking distance South from NTU Hospital Station of the Taipei Metro.
