The Global Climate Observing System (GCOS) Reference Upper-Air Network (GRUAN) has evolved from aspiration to reality and is now delivering reference-quality -upper-air data products to a variety of users.
GRUAN has transformed since the 2005 workshop to define its observational requirements, from a plea by climate researchers for reference upper-air measurements to a concept for a global network providing such measurements to a community collaborating to actualize coordinated, certified measurement programs at sites comprising a truly reference-quality climate observing network.
This paper documents the next chapter in the story of how the GRUAN community has progressed in achieving the goal of constructing an observing network that, ultimately, will meet the challenges of climate science in the twenty-first century.
Key aspects of the GRUAN chronicle, summarized here, are the organization and management of GRUAN; the establishment and certification of network sites; the current and planned data products; the scientific basis for GRUAN operations; and GRUAN's contributions to the broader GOS.
A key recent development has been the publication of The GCOS Reference Upper-Air Network (GRUAN) Manual (WMO 2013b) and The GCOS Reference Upper-Air Network (GRUAN) Guide (WMO 2013a).
To fulfill the requirements for reference observations, each GRUAN product emanates from a tailored raw data and metadata collection tool, deployed at each measurement site, to collate, screen, verify, and transmit to a centralized processing facility the data and metadata required to generate the product.
In our consideration of GRUAN standards for radiosonde data, it is important to consider GRUAN as an international collaboration.
For that reason, we support international collaborative efforts similar to that of GRUAN for glidersonde development, and underscore the necessity of an avenue to address private availability of the COA/SAC and license processes.
