The service consolidates global weather information from multiple sources for standardized access via a single XML interface. Applications can retrieve current weather forecast information for most locations in the world via an adaptation of the Global Forecast System numeric weather model. Created to meet needs of flight planning, the service also supports forecasting needs for land transportation, agriculture, and other applications.
API methods return current temperature, winds aloft, and other general weather information for a specified location, along with forecasted weather conditions and charts. Methods also provide descriptions of terrain and altitude, as well as archives of past weather conditions for a given time and location.
