An adaptive weather interrogation system capable of determining whether currently available weather for a particular trajectory or portion thereof, a particular volume of space or geospatial point meets subscriber operations and requirements. More specifically, the system provides the capability to determine the “best” weather information by evaluating the weather data and associated weather quality, accuracy or confidence attribute values against subscriber operations and requirements. If the weather data, quality, accuracy, and confidence do not meet the subscriber's requirements, the system is capable of interrogating weather data sources for additional or updated weather data to meet the subscriber's needs.
