The Global Heat Health Information Network (GHHIN) Health Advisor will work under the overall guidance of the Senior Director of the Services Department (D/S) and report directly to the Head of the WHO-WMO Climate and Health Joint Office. The Health Advisor will oversee and ensure the technical integrity of GHHIN's workstreams and support the World Meteorological Organization (WMO) in its activities on extreme heat and health. Additionally, the Health Advisor will have a unique role to also support the World Health Organization (WHO) in deploying and coordinating the extreme heat activities that WHO contributes to the Network to ensure alignment. The Health Advisor will also work to strengthen collaboration between global and regional partners in addressing the health risks associated with extreme heat.

The GHHIN Health Advisor will be a core member of the Network Technical Support Unit (TSU), working in close cooperation with the GHHIN Network Coordinator, Climate Services Network Coordinator, Extreme Heat Services Advisor, and Communications team. The Health Advisor is expected to oversee, coordinate, and ensure technical integrity of GHHIN’s workstreams and projects. Specifically including:
