More Stations. More Data. Better Forecasts.

A world-class network of environmental monitoring stations.

In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at least one site in every county. Each site will measure temperature, humidity, wind speed and direction, pressure, radiation, and soil information. Special subsets of 17 sites will provide additional atmospheric data in the vertical (up to 2 miles above ground), flux (the amount of heat and moisture exchange near the ground) and snow depth information. All data will be collected, archived, and processed in real-time, feeding weather prediction models and decision-support tools for users across the greater New York region.

How it Works

The New York State Mesonet, when completed, will consist of 125 stations across the state. Each station will house a suite of automated sensors, sampling data every 3 to 30 seconds. Data are then packaged into 5 minute averages, and then transmitted in real-time to a central facility located at the University at Albany (UAlbany). At UAlbany, data from all sites are quality-controlled, and then processed into files which are then disseminated to customers for use in forecasting and decision-making.


  • Over 1,670 sensors producing over 500,000 observations per day
  • In-house calibration
  • Routine Field Maintenance


  • 24/7 data ingest
  • Automated quality control
  • Automated file generation
  • Real-time visualization

Product Generation

  • Real-time data feed to partners
  • Real-time 3D analyses
  • Short-term, regional forecasts
  • Value-added products for Emergency Management, Transportation, Energy, Education, and Agriculture


The New York State Mesonet is designed, implemented and operated by scientists at the State University of New York at Albany with support from the New York State Division of Homeland Security and Emergency Services.

High Definition Analyses and Forecasts

Data and derived products from the New York Mesonet will improve weather analysis and prediction, empower emergency management, expand education and research opportunities, and enable more efficient economic decisions.


The Mesonet will provide four-dimensional imagery of the weather, allowing more accurate, more reliable forecasts and decision-making.

Emergency Management

Emergency managers will have access to immediate weather information across urban and rural New York, making for safer, more effective disaster preparation and response.

Research and Education

As an “end-to-end” system, the New York State Mesonet provides a truly unique learning environment, with research activities ranging from the physical sciences (climate, micrometeorology, instrumentation, numerical weather prediction) to computer science, mathematics, economics, and sociology.


Data from the Mesonet are expected to save millions of dollars through more efficient, more cost-effective road weather mitigation, aviation services, agricultural practices, and energy production.
