Ground-based GNSS atmospheric monitoring for weather and climate resilience

Amid the growing challenges of climate change impact and the fairly limited availability of observations of some Earth system parameters, this article highlights the potential of ground-based Global Navigation Satellite Systems (GNSS) atmospheric monitoring as a supplementary satellite observing technique to improve the monitoring and forecasting of weather and climate extremes. It spotlights current barriers and future opportunities, aiming to heighten public and institutional awareness of the research and application status and the prospective role of GNSS atmospheric monitoring for weather and climate resilience. The innovative uptake of diverse ground-based GNSS atmospheric parameters could support improved systems and policies for risk management and climate adaptation, thus empowering communities to better withstand hazardous weather and climate extremes.
