Also, the addition of Doppler velocities increased the ability for severe weather detection and warning by allowing forecasters to see wind fields and possible rotation within thunderstorms. It increased the resolution of the data, allowing forecasters to see storms in much finer detail. The NEXRAD System provided marked improvements for the NWS. After being developed and tested through the 1980s by the NOAA National Severe Storms Laboratory and partners, the first of these Next-Generation Radar systems (NEXRAD) were deployed operationally beginning in 1992. This allowed forecasters not just to see location and intensity of the precipitation along with basic storm movement, but the movement of the precipitation and winds within the storm itself. NWS Wilmington (OH) WSR-57 Radar image of supercells with hook echoes during 1974 Super Outbreak (courtesy of NCDC)Īround the same time period, researchers began developing a new generation of radars that would incorporate the use of Doppler radar. These radars provided similar data but with newer and more reliable components. An updated version, the WSR-74, supplemented and replaced the older radars beginning in 1977. The technology was refined and in 1959 the NWS began rolling out its first network of radars dedicated to a national warning network. Navy donated 25 surplus radars to the NWS (then known as the Weather Bureau), marking the start of a U.S. Investigation into this phenomenon resulted in the discovery that these echoes were returns from the precipitation, unmasking a further use for the technology. Analysts noted in periods of heavy weather, the radar would return strange signals. But the use of radar for weather observations occurred by accident. The concept of RAdio Detection and Ranging (Radar)began in the late 1800’s and by World War II, radar was in use by militaries around the world, scanning for incoming airplanes. The International Radar Aeroecology Conference 2019 was held in Zhengzhou China from 21 – 24 September 2019.Doppler radar sends the energy in pulses and listens for any returned signal. The GloBAM project website can be found at: One such initiative is GloBAM which involves several ENRAM members. While the COST Action has officially ended, the network is still functioning and generating new initiatives. Thereby the already existing monitoring efforts and prediction of animal movement patterns can be coordinated and extended to a continental scale.īy establishing this coordinated network of international scientists and its multi-disciplinary approach ENRAM will consolidate Europe’s world leading position in the use of radar for animal movement studies, taking this area of science a major step forward. Researchers from across Europe and a wide range of expertise – including ecology, biogeography, ornithology, entomology, meteorology, mathematics and engineering – will join forces in the field of aeroecology to foster continental-scale remote sensing of animal migration for the first time.
