This document provides a roadmap for the further development of the Global Climate Observing System (GCOS) Reference Upper-Air Network (GRUAN) for the period 2024 to 2030. It serves as an update to, and supersedes, the previous GRUAN Implementation Plan (GCOS-205). It details the high-level objectives required to reach the goal of maintaining a fully operational reference upper-air network for climate and developing GRUAN data products (GDPs) for Priority 11 variables and starting to work towards GDPs for Priority 22 variables. It also highlights relevant actions in the latest GCOS Implementation Plan (GCOS-244) on which GRUAN is expected to contribute. It should be interpreted in conjunction with the GRUAN Manual and Guide (GCOS-170 and GCOS-171 respectively). The new GRUAN Implementation Plan (IP) is similar to the previous IP.
