4 to 6-May-2011 Waikiki Beach Mariott Resort and Spa Honolulu, Hawaii Hydrographic Products and Services in support of Climate Services in the Pacific Islands Hydrographic Service Review Panel

VISION: Resilient and sustainable communities using climate information to manage risks and support practical decision-making in the context of climate variability and change. Climate Services “A mechanism to identify, produce, and deliver authoritative and timely information about climate variations and trends and their impacts on built, social-human, and natural systems on regional, national, and global scales to support decision making.” (NRC, 2009)
