Regional Climate Centres (RCCs) are designed to assist WMO Members in a given region to deliver better climate services and products including regional long-range forecasts, and to strengthen their capacity to meet national climate information needs. The primary "clients" of a RCC are National Meteorological and Hydrological Services (NMHSs) and other RCCs in a region and in neighbouring areas. RCC responsibilities are regional by nature and not duplicate or replace services provided by NMHSs. RCCs serve the regional level of a three-level (climate-related) infrastructure: Global Producing Centres (GPCs, global level), Regional Climate Centres (RCCs, regional level), National Meteorological and Hydrological Services (NMHSs, national level).
