GRUAN Manual and Guide published


Over the last three years the GRUAN Manual and Guide have been developed in a strong community effort and have now been endorsed by all GRUAN participants. These documents are now published as joint GCOSWIGOS documents (GCOS-170 and GCOS-171)  and outline what is expected from GRUAN stakeholders such as the Lead Centre, the Working Group on GRUAN (WG-GRUAN) and participating sites to achieve the goals of this network. Mandatory operating protocols and desirable activities are described therein, as well as the criteria for site assessment and certification. It is expected that specific details from these documents as well as information about GRUAN will be included in WMO’s regulatory material.
