LOUISIANA STATEMesonet
Mesonets are interconnected networks of automated weather stations installed across an entire state or region.
Typically, each station collects data on temperature, humidity, pressure, solar radiation, wind, and precipitation every 3 to 60 seconds. Some include soil conditions or cameras for real-time visual confirmation.
Approximately 30 mesonets are established across the U.S., filling critical coverage gaps in the federal weather observing network.
View National Mesonet ProgramIn the past 20 years, Louisiana has experienced 46 billion-dollar weather and climate disasters. The Mesonet provides "ground truth" observations that improve nowcasting and resource management.
By filling current coverage gaps, we provide officials with more accurate indications of conditions hazardous to life and property.
Provides forecasters localized information to improve warnings for severe weather that currently falls between NWS gaps.
Real-time dispersion modeling for industrial accidents or airborne threats, facilitating rapid emergency response.
Critical ground-level data for pilots to reduce fuel expenditures and improve arrival/departure safety.
Helps estimate energy needs, protect infrastructure, and optimize placement for wind/solar farms.
Supports a $3B industry with data for irrigation, pest spraying, and frost protection to prevent crop loss.
Enables state agencies to deploy resources for road closures and motorist alerts accurately.
Unique STEM learning opportunities for K-12 and universities, supporting grant funding from NOAA and NASA.
