Hurricane Katrina in 2005

On May 15, 2013, celebrated a significant milestone—200,000 classifications! A collaborative project among NCDC, the Cooperative Institute for Climate and Satellites–North Carolina, the University of North Carolina–Asheville, and the Citizen Science Alliance, aims to address uncertainties in the global tropical cyclone record by enlisting volunteers from the public to help classify tropical cyclone imagery.

Nearly 300,000 hurricane images—more than a full-length motion picture has movie frames—must each be analyzed 30 times to fully develop a new global tropical cyclone dataset with 3-hourly tropical cyclone intensity estimates, confidence intervals, and a wealth of other metadata that could not be realistically obtained in any other fashion. The classification of 200,000 images would take a single scientist over 8 years, while citizen scientists have completed the same job in less than 8 months!

Check out and invite your friends, relatives, and colleagues to start classifying today!
