AOPC-22 (Exeter, UK, March 2017) agreed on the creation of a dedicated task-team to scope a potential GCOS Surface Reference Network. The potential for such a network has been proposed by GCOS AOPC and by the Commission for Climatology. This Task Team is charged with taking this forwards towards practical implementation providing a concrete roadmap as to what would be required and to canvas stakeholders. Working models on which to base deliberations include the GCOS Reference Upper Air Network, US Climate Reference Network, and Global Cryospheric Watch.
