Mesoscale Weather Data in Real Time

A network of networks for improved weather prediction, warnings, and emergency response across the U.S.

Overview

The National Mesonet is the central repository for real-time collection and dissemination of non-federal surface, boundary layer and tropospheric atmospheric weather observations in the US. These observations substantially augment the nation’s backbone of monitoring infrastructure and significantly improve weather prediction, severe weather warnings, and emergency response for all regions of the country. Data from the National Mesonet also serves as a critical resource to aid business leaders, policy makers, and researchers in key decision making that affect every segment of the US economy including the highly weather-sensitive security, transportation, and energy sectors.
