Purpose of CWOP Private-public partnership with goals:
1. Collect weather data contributed by private citizens;
2. Make these data available for public and private weather services;
3. Provide feedback to the contributors so they have tools to improve data quality.

Wind reported by Gus Campbell’s CW1550 CWOP weather station on UTC day March 6, 2004,
showing 53 mph wind gust reported at 3:51 PM EST.

Main Take-Home Points
• If you are in a sparsely populated area, then your station may give the only weather reports for many miles in any direction; there are many gaps of over 100 miles in US.
• If you are in a densely populated area, then your station may be the only weather station that sees a small scale weather event (like the Baltimore Harbor gust).
• In all cases, running a weather station is great way to “give back” to your local community.
