The Office for Coordination of Climate Change Observation (OCCCO) supports the activities of Japanese Alliance for Climate Change Observation (JACCO). The JACCO was established by the Ministry of the Environment (MOE) and the Japan Meteorological Agency (JMA) in April 2006 to plan and coordinate comprehensive and integrated climate change observation systems. The OCCCO, located in the Center for Global Environmental Research (CGER) of the National Institute for Environmental Studies (NIES), performs the following activities: (1) the assessment of the need for climate change observations, (2) the enhancement of the accessibility of observation data, and coordinating the use of observational platforms of relevant organizations, (3) managing of public relations activities, and (4) convening of meetings for promoting JACCO's activities.


The conference "Global Climate Observation: the Road to the Future" by GCOS (Global Climate Observing System) is held from 2-4 March 2016 at the Royal Academy of Arts and Sciences, Amsterdam.
