Use of Mode-S Radars for Extracting of Meteorological Data from Aircraft

Popis výsledku v původním jazyce

Each day, Central Europe is being overflown by hundreds of airplanes equipped by Enhanced Mode S communications and advanced avionics capable to report meteorologically related parameters to ground via Air Traffic Control infrastructure. Preliminary study of using aircrafts as meteorological sounding sensors by means of direct (MRAR - Meteorological Routine Air Report) and indirect (EHS = Mode-S Enhanced Surveillance) calculations is being performed in the Czech Republic. Monoradar reports in standard EUROCONTROL format ASTERIX Category 048 from 3 national and 3 external Mode-S radars are used for on-line extraction of relevant Comm B (BDS) transponder register data, aircraft location and 24-bit ICAO address. Meteorological parameters: wind speed, direction and air temperature are available in about 10 second increments during the entire flight inside Mode S radar coverage. Huge amount of derived meteorological data needs to be smoothed and quality controlled first, but it can create a promising cheap alternate source of meteorological measurements in the free atmosphere, complementing the traditional and expensive aerological soundings and AMDAR-type measurements. Resulting wind and temperature profiles as near real-time data can be used for input to meteorological models (NWP - numerical weather prediction) or for air traffic control itself, especially for refinement of 4D-trajectory calculations. Preliminary statistics of horizontal, vertical and temporal coverage of both MRAR and EHS meteorological data are given, based on half-yearly statistics. Unfortunately, the coverage depends on typical air traffic patterns, so there are important gaps during nighttime and in lower levels, depending on airspace structure and restricted areas. More precise MRAR data are rather rare, available only in about 3% of the reports.
