The U.S. continues to be an active participant in and large supporter of the international Global Climate Observing System (GCOS) program. As part of an international effort, and in response to a United States Presidential Climate Change Research Initiative, the U.S. has formulated a Framework for International GCOS Support plan. This plan focuses on the status of GCOS, what is needed to bring GCOS to its operational-design level, and the support needed from the scientific, donor, and host communities to implement selected improvements to it. In particular, the plan focuses on needed improvements to meteorological surface-based networks. A discussion of the specifics of this support as well an update of the overall U.S. program from last year, and the current status of the GCOS Surface Network (GSN) and GCOS Upper Air Network (GUAN) will also be included.
