AiR Pollution - Climate Change - Health Effects Nexus Working Group

The Air Pollution–Climate Change–Health Effects Nexus Working Group (ARCH) operates under the Global Atmosphere Watch (GAW) Programme of WMO. It strengthens research and coordination at the air-climate-health interface. For 2024–2027, it will implement a work plan to guide cooperation, capacity building, and data sharing; map GAW activities; and foster collaboration with WMO, WHO, and UNEP. ARCH will define research needs, promote integrated studies, support global initiatives like EW4All, publish an Air-Climate-Health Report, and establish a Coordination Office at Peking University.

Working groups

The Air Pollution - Climate Change - Health Effects Nexus Working Group (ARCH WG) is designed to help coordinate GAW activities that support health-related strategies.

ARCH assists GAW in contributing to requests 1 and 2 in the WMO Cg-19/Doc resolution. 4.1(8), which are:

  1. To work with the Research Board to establish appropriate mechanisms for the effective support of the WMO-WHO Joint Climate and Health Office and implementation of WMO Integrated Health Services; and;
  2. To help support the Technical Commissions and the Research Board to responsively co-design with the research and health community products and services required to support public health by all Members effectively and to assist in strengthening the capacities of the NHMSs and other providers and users of health-tailored information services.

Specifically, the ARCH WG works with various GAW Expert Teams and Scientific Advisory Groups, the WMO-WHO and the GAW Scientific Steering Committee, with the aim to:

  1. identify and catalogue ongoing GAW activities involving health effects of air pollution, climate change, and solar UV radiation,
  2. identify important gaps and potential needs for other possible activities,
  3. propose an action plan for GAW to address the identified gaps,
  4. and coordinate GAW activities that support the WMO health-related strategies

As a first step of setting up ARCH, we are performing the survey to identify and recognize common interests, opportunities, gaps and needs across GAW working groups, WMO Research Board, Regional Associations, National Meteorological and Hydrological Services (NMHSs), Universities, Research Centers, etc. We appreciate your taking the time to provide the input!

The ARCH survey is available HERE.
