1 CITIZEN WEATHER OBSERVER PROGRAM CWOP – 3300 citizen weather stations worldwide Russ Chadwick, NOAA Earth System Research Laboratory

2 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.

3 Weather station APRS Servers Weather station APRS-IS findu.com database GSD Central Facility CWOP database MADIS I-Gates OtherUsers WFOs AWIPS UCAR NCEP MesoWest RF Mobile station RF CWOP Data Flow

4 Private-Public Partnership Data Collection (privately owned and operated) –WX stations operated by private citizens –Data transfer by APRS-IS (internet service) –Data management by findU.com Data Distribution (provided by NOAA) –Data distribution by MADIS –Data quality checking by QCMS –NOAA GSD Central Computer Facility

17 BALTIMORE HARBOR WATER TAXI ACCIDENT At about 4:00 PM EST on March 6, 2004, a sudden gust of wind overturned a water taxi carrying sightseers around Baltimore Harbor. There were five fatalities.

18 CW1550 Accident Site Location of Gus Campbell’s CW1550 CWOP Weather Station Five Miles WSW of the Water Taxi Accident Site

19 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.

20 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.
