• Weather is highly localized. To truly capture this variability,you need to measure it locally.
• The National Weather Service (NWS) measures weather at 1400+ points across U.S. Measurements are provided once an hour. Points located primarily at Airports.
• NWS sites are often too far away to capture the information needed. The update frequency often misses an event.
• If you can place weather stations where you need data, collect that data often, you can improve decision making.
Meso Network Concept

If you agree that more localized data can improve your ability to gauge storm severity, deploy crews more efficiently, and correlate your outages to weather thresholds, you have two options:
Meso Network Concept
• Build It – Secure a number of weather sensors, site, install, maintain, centrally collect the data, and create tools to view and analyze the data.
• Buy It – Find a Company that operates a localized weather network, and provides access to it’s data.

Today’s Agenda
![Page 13: Severe Weather and the Impact on Utility · your outages to weather thresholds, you have two options: Meso Network Concept • Build It–Secure a number of weather sensors, site,](https://reader031.vdocument.in/reader031/viewer/2022011817/5e82b8859325822b155ddb43/html5/thumbnails/13.jpg)
• Analyze the exiting coverage in your Service Territory– NWS Stations– WeatherBug® Stations– Other Local Networks
• Identify “holes” in coverage. Consider weather station purchase
• Look at surrounding Regions to gauge ability to capture approaching weather
Employing a Meso Network
![Page 14: Severe Weather and the Impact on Utility · your outages to weather thresholds, you have two options: Meso Network Concept • Build It–Secure a number of weather sensors, site,](https://reader031.vdocument.in/reader031/viewer/2022011817/5e82b8859325822b155ddb43/html5/thumbnails/14.jpg)
Example of Uniform Coverage
Broward County
84 Stations representing 21 County and Local Agencies
![Page 15: Severe Weather and the Impact on Utility · your outages to weather thresholds, you have two options: Meso Network Concept • Build It–Secure a number of weather sensors, site,](https://reader031.vdocument.in/reader031/viewer/2022011817/5e82b8859325822b155ddb43/html5/thumbnails/15.jpg)
• Consider placing weather stations and cameras at critical infrastructures to view changes and impacts
• Target historical “problem areas”, or remote locations. If elevation varies greatly across territory, ensure representative coverage.
Placing Stations for Maximum Benefit
![Page 16: Severe Weather and the Impact on Utility · your outages to weather thresholds, you have two options: Meso Network Concept • Build It–Secure a number of weather sensors, site,](https://reader031.vdocument.in/reader031/viewer/2022011817/5e82b8859325822b155ddb43/html5/thumbnails/16.jpg)
• Sensor placement is critical in achieving optimal accuracy in readings.
• Data collection and reliability of reports is critical. Finding locations with 24/7 operations, and back‐up power is preferred.
Site Selection
