Systems and methods communicate sensor data pertaining to detected weather between aircraft. An exemplary system has at least one sensor on a transmitting aircraft that is configured to detect weather and configured to output sensor data, and a transceiver that is configured to receive a query from a requesting aircraft for the sensor data and that is configured to transmit a signal with the sensor data for receipt by the requesting aircraft in response to receiving the query. Upon receipt by the requesting aircraft, the received sensor data of the transmitting aircraft may then be fused with sensor data of the requesting aircraft for a geographic region of interest to extend the effective sensor coverage and to resolve at least one of a location conflict and a severity conflict between the sensor data of the transmitting aircraft and the requesting aircraft.
