Global Observing Systems Information Center (GOSIC) - NOAA
The GOSIC Portal serves as a clearinghouse providing convenient, central, one-stop access to data and information related to the Global Climate Observing System (GCOS)(link is external). The GCOS is a long-term, user-driven operational system capable of providing the comprehensive observations required for monitoring the climate system, for detecting and attributing climate change, for assessing the impacts of climate variability and change, and for supporting research toward improved understanding, modelling and prediction of the climate system. The GCOS addresses the total climate system including physical, chemical and biological properties, and atmospheric, oceanic, terrestrial hydrologic, and cryospheric components.
