The RA II Working Group on Weather, Climate, Water and Related Environmental Services and Applications supports WMO and RA II decisions on weather, climate, water, and environmental services. It identifies service gaps, advances initiatives like GMAS and Regional Climate Forums, and develops regional roadmaps and implementation plans. The group coordinates with SERCOM, monitors regional centres, promotes capacity-building and knowledge sharing, supports the State of the Climate in Asia report, and submits annual progress reports.
