Airborne based monitoring
InactiveUS6937937B1Improve weather forecastsOptimize aircraft routingWeather condition predictionClear air turbulence detection/forecastingAir traffic controlEngineering
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.

Apparatus and method for monitoring and reporting weather conditions
InactiveUS6085152AEasy to useEasily select displayIndication of weather conditions using multiple variablesCharacter and pattern recognitionTerrainLight response
A weather monitoring, measuring and reporting system which uses unattended, high-resolution digital cameras and laser rangers to both measure and display weather conditions in a local region, such as the region surrounding an airport. Visibility is estimated by processing images in the camera's field of view at known range distances. The light response of the camera is matched to the light response of the human eye. In a preferred embodiment of the invention, the camera generates a digital pixel image of range objects; that is, prominent terrain objects such as, buildings, water towers, etc. in the camera's field of view. The digital pixel values of these range objects are stored in system memory at known address locations. The contrast between an average background pixel value in a region adjacent to an object and the average object pixel value is used to determine if the object is visible. Objects in the field of view are sequentially examined until the contrast to an object falls below the established threshold at which point the visibility is reported as extending to the next closest object with a contrast above the threshold. If the contrast for all objects exceeds the threshold, the process stops and the visibility range is reported as unlimited.

Systems and methods for calibrating dual polarization radar systems
A dual polarization radar system is calibrated based on real-time data measurements, such as measured horizontal and vertical reflectivities, ZH and ZV. In this regard, the radar system analyzes the reflected power measurements to identify which measurements are associated with reflections from a respective spherical object. Using such measurements, the system determines a system differential reflectivity value, and combines such value with reflected power measurements for calibration. Since the calibration is based on real-time data measurements, the calibration process may run simultaneously with the collection of weather data. Further, the calibration process is immune to the weather events within range of the radar system. Accordingly, it is possible for the calibration to be performed at any time and without interfering with the weather monitoring activities regardless of the types of weather events occurring within the vicinity of the radar system.
