A weather data collection system, the system comprising: at least one transceiver configured to communicate with aircraft via one or more datalinks; a Weather Data Processing System coupled to the at least one transceiver, the Weather Data Processing System comprising a processor coupled to a memory that stores weather information compiled from aircraft collected weather data; wherein the Weather Data Processing System further comprises a Weather Information Collection Manager coupled to the at least one transceiver and the memory, the Weather Information Collection Manager implemented by the processor; wherein the Weather Information Collection Manager is configured to process a new weather data disclosure message received from a first aircraft via the at least one transceiver to determine when the first aircraft has a first set of aircraft collected weather data available for transfer that is either cumulative or noncumulative with respect to weather information previously stored in the memory, wherein the new weather data disclosure message comprises a message indicating that the first aircraft has generated a new set of aircraft collected weather data, and a first set of aircraft collected weather data is determined to be cumulative with respect to weather information previously stored in the memory when the first aircraft is within a predetermined range with respect to a second aircraft that previously provided at least part of the weather information previously stored in the memory and is travelling with the same heading as the second aircraft wherein the Weather Information Collection Manager is further configured to process the new weather data disclosure message received from the first aircraft to determine whether a first datalink of the one or more datalinks is suitable for transferring the first set of aircraft collected weather data; and wherein when the first set of aircraft collected weather data is noncumulative and when the first datalink of the one or more datalinks is suitable for transferring the first set of aircraft collected weather data, the Weather Information Collection Manager is configured to cause the Weather Data Processing System to transmit a weather data request to the first aircraft in response to the new weather data disclosure; wherein the Weather Information Collection Manager determines whether the first datalink is suitable for transferring the first set of aircraft collected weather data based in part on at least one of: a current utilization and availability of the first datalink, an availability of datalink bandwidth of the first datalink to transmit the aircraft collected weather data, and on a data size associated with the aircraft collected weather data. at least one transceiver configured to communicate with aircraft via one or more datalinks; a Weather Data Processing System coupled to the at least one transceiver, the Weather Data Processing System comprising a processor coupled to a memory that stores weather information compiled from aircraft collected weather data;
