Abstract

A weather monitoring and prediction system that uses a fleet of aircraft to obtain data. Each aircraft has a local air data system that facilitates the measurement, recordation, and transmittal of local atmospheric data such as barometric pressure, and the corresponding temporal, positional, and altitudinal data. The data is electronically transmitted from each aircraft to a ground based processing system where it is stored. The data may then be transmitted to subscribing users such as aircraft, other weather data systems or to air traffic control centers in either a compiled form or in a raw form. Another embodiment also provides for measuring barometric pressure as a function of altitude at an in-flight aircraft.

Claims

1. A weather monitoring system comprising:

within each of a plurality of monitoring airplanes;

a local air data system for recording data on local atmospheric conditions;

primary measurement means comprising a static air pressure transducer for measuring local atmospheric conditions;

at least one secondary measurement means for measuring positional, altitudinal, and temporal data without reference to local atmospheric conditions,

wherein each local atmospheric datum measured by the primary measurement means is corecorded with a recordation time representing the time of measurement, a recordation position representing the position of the aircraft at the time of measurement, and a recordation altitude representing the altitude of the aircraft at the time of measurement;

within one or more ground-based processing centers;

electronic reception equipment for autonomously receiving data from monitoring airplanes, wherein the atmospheric, positional, altitudinal, and temporal data are transmitted to the ground based processing centers for compilation;

means for receiving and compiling the atmospheric, temporal, altitudinal, and positional data from each monitoring aircraft to create a set of predictive indicia; and

means for advising the subscribing user of upcoming weather conditions.

2. The weather monitoring system of claim 1, wherein the set of predictive indicia is atmospheric pressure as a function of altitude, position, and time.

3. The weather monitoring system of claim 2, further comprising local communication means for transmitting the recorded data from the static air-pressure transducer to the local air data system.

4. The weather monitoring system of claim 3, wherein the local communication means for transmitting the recorded data from the static air-pressure transducer to the local air data system comprise:

a wireless transmitter electronically connected to the static air-pressure transducer; and

a wireless receiver electronically connected to the local air data system.

5. The weather monitoring system of claim 1, wherein the plurality of monitoring airplanes comprise a fleet of commercial, military, or business airplanes.

6. The weather monitoring system of claim 1,

wherein the subscribing user comprises a plurality of subscribing aircraft and

wherein an aircraft can be both a monitoring airplane and a subscribing aircraft.

7. The weather monitoring system of claim 6, where the means for advising subscribing aircraft of upcoming weather conditions comprise:

electronic transmission and reception equipment for autonomously transmitting data between the ground-based processing center and each subscribing aircraft; and

8. The weather monitoring system of claim 7, wherein the electronic transmission and reception equipment for autonomously transmitting data between each monitoring aircraft and the ground-based processing centers are configured to autonomously transmit the atmospheric, temporal, altitudinal, and positional data from the monitoring aircraft to the ground-based processing center.

9. The weather monitoring system of claim 7, wherein the subset of predictive indicia is indicative of current or upcoming turbulence in the planned or alternative flight path of the given subscribing aircraft.

10. The weather monitoring system of claim 1, wherein data bandwidth limitations are substantially overcome by a means selected from the group transmission delay, data compression, and message prioritization.
