GBON - Global Basic Observing Network

Accurate local weather forecasts rely on continuous access to global observations. However, significant geographical gaps still exist. In some regions, data collection or international exchange is limited or irregular.

The Global Basic Observing Network (GBON) is an essential part of the WIGOS framework. It introduces a globally coordinated approach to design, define, and monitor surface-based observation systems. Once fully implemented, GBON will enhance the availability of key meteorological data, improving forecast accuracy and promoting global safety and well-being.

Implementation and Compliance

According to decisions from the 2021 Extraordinary World Meteorological Congress, several steps have been launched to ensure GBON’s establishment and monitoring.

Regulations and Enforcement: GBON Technical Regulations will take effect on 1 January 2023.
Infrastructure Commission: It will create technical guidelines, operational procedures, and compliance mechanisms for efficient implementation.
Global Readiness: Most developed WMO Member States are expected to implement GBON quickly.
Support for Developing Nations: Additional investment and capacity-building initiatives are required in many developing countries. WMO will collaborate with international development and climate finance organizations to achieve this.

“GBON represents a new global approach to ensure continuous, high-quality surface-based weather observations.”

Outlook

Once operational, GBON is set to strengthen the foundation of international meteorological monitoring, benefitting communities worldwide through improved forecasting capabilities.

Author’s Summary: GBON creates a unified global framework for continuous surface-based weather observations, raising forecast quality and enhancing worldwide climate resilience.
