Weather Underground has launched a new automated API service which gives developers access to in-depth weather data.

Once registered, developers can select from three Feature Plans depending on the depth of weather data they require. On the lowest usage plan, all data is free and can be integrated into developers' applications without any charges.

Alan Steremberg, President and co-Founder of Weather Underground explained:

"Weather Underground already distributes its weather data to many of the world's leading media companies, weather applications and smaller web properties. Our new self-service API platform will open up our data to thousands more developers working on web and mobile programs, big and small. With the recent surge in the number of location-based applications, we hope that our new API platform will further disseminate all of the unique weather data and proprietary forecasts that we generate for wunderground.com."

In addition to providing access to the world's largest network of personal weather stations, Weather Underground's API product includes free analytical tools that provide usage metrics and reports.

The platform is  scalable and developers can automatically select higher usage plans if and when they are required. Data feeds are currently available in JSON and RESTful with more format options coming soon.
