|Paper title||WMO and GCOS – facilitating observations and leveraging data exchange for climate and greenhouse gas monitoring|
|Form of presentation||Poster|
Climate information is essential for monitoring the success of our efforts to reduce greenhouse gas emissions that contribute to climate change, as well as for promoting efforts to increase energy efficiency and to transition to a carbon-neutral economy. The WMO Integrated Global Observing System (WIGOS) promotes network integration and partnership outreach, and engages the regional and national actors essential for successful integration of these systems. The WIGOS Vision for 2040 outlines the ground and space-based capabilities that are required in 2040 to deliver the observations required. These data and observations rely on the Global Climate Observing System (GCOS), which maintains the requirements of Essential Climate Variables (ECVs), and support additional observational needs that are required to systematically observe Earth`s changing climate and is such underpin climate research, services and adaptation measure.
The 2021 Extraordinary World Meteorological Congress approved the new WMO Unified Data Policy, along with two other sweeping initiatives – the Global Basic Observing Network (GBON) and the Systematic Observations Financing Facility (SOFF) – to dramatically strengthen the world’s weather and climate services through a systematic increase in much-needed observational data and data products from across the globe. Approval of the Unified Data Policy provides a comprehensive update of the policies guiding the international exchange of weather, climate and related Earth system data between the 193 Member states and territories of WMO. The new policy reaffirms the commitment to the free and unrestricted exchange of data, which has been the bedrock of WMO since it was established more than 70 years ago.
The Global Basic Observing Network (GBON) is a landmark agreement offering a new approach in which the basic surface-based observing network is designed, defined and monitored at the global level. It paves the way for a radical overhaul of the international exchange of observational data, which underpin all weather, climate and water services. This becomes increasingly important also for climate and greenhouse gas monitoring, when the ground-based and space-based components are used in an integrated fashion. Data from programmes like the WMO Global Atmospheric Watch (GAW) and Integrated Global Greenhouse Gas Information System are key for a comprehensive analysis and monitoring of greenhouse gases and climate and will play an increasingly important role supporting satellite observing systems providing ground-truth and much required data for satellite calibration and validation activities. The new WMO Data policy, and GBON, provide the tools and mechanisms to further evolve these systems to meet future needs for a comprehensive climate, greenhouse gas and carbon monitoring system.
This presentation will give an overview of the above elements and how WMO and GCOS support greenhouse gas and climate monitoring activities and facilitates and leverages access to ground-based observations in response to global needs.
