We show that weather radar can extract near real-time bird density altitude profiles that closely correspond to the density profiles measured by dedicated bird radar.

These weather radar bird observations have been validated with data from a high-accuracy dedicated bird radar, which was stationed in the measurement volume of weather radar sites in The Netherlands, Belgium and France for a full migration season during autumn 2007 and spring 2008. During development the system was tested on the NASA B757 aircraft and final tests were conducted on the Rockwell Collins Sabreliner.īird migration flight altitudes studied by a network of operational weather radars.ĭokter, Adriaan M Liechti, Felix Stark, Herbert Delobbe, Laurent Tabary, Pierre Holleman, IwanĪ fully automated method for the detection and quantification of bird migration was developed for operational C-band weather radar, measuring bird density, speed and direction as a function of altitude. A flight path impact prediction algorithm was developed to help pilots to avoid hazardous weather along their flight plan and their mission. Cell attributes are determined based on data from the on-board radar and from ground-based radars. A rule-based decision aid was developed to automatically characterize cells as hazardous, possibly-hazardous, or non-hazardous based upon attributes of that cell.
The on-board weather radar includes an automated or hands-free storm-finding feature that optimizes the radar returns by automatically adjusting the tilt and range settings for the current altitude above the terrain and searches for storm cells near the atmospheric 0-degree isotherm.
The system will simultaneously display NEXRAD and on-board weather radar information in a split-view format. National Weather Service (NWS) ground-based Next Generation Radar (NEXRAD) information is used by the EWxR system to augment the on-board weather radar information. The system features additional weather data that is uplinked from ground-based sources, specialized data processing, and limited automatic radar control to search for hazardous weather. Activities carried out during a trip to the radar facilities at Phuket are described.Īn airborne weather radar system, the Enhanced Weather Radar (EWxR), with enhanced on-board weather radar data processing was developed and tested. Quality data are needed from those systems to support TRMM and other scientific investigations. This grant provides for some investigations related to weather radar measurement techniques applicable to meteorological radar systems in Thailand. Most of the activity took place during two visits to Thailand, in December 1990 and February 1992. Weather radar calibration techniques were also considered during this project. A major part of the activity was devoted to instruction and discussion with Thai radar engineers, technicians, and meteorologists concerning the basic principles of radar meteorology and applications to specific problems, including measurement of rainfall and detection of wind shear/microburst hazards. Research relative to weather radar measurement techniques, which involves some investigations related to measurement techniques applicable to meteorological radar systems in Thailand, is reported.
