1994 The Verification of the Origins of Rotation in Tornadoes EXperiment (VORTEX) begins. 1991 NSSL participates in the Cooperative Oklahoma Profiler Studies of 1991 (COPS-91) and uses instrumented aircraft and a ground-based network of instruments to sample tornadic supercells. WDSS contains a combination of sophisticated severe weather detection algorithms and an innovative, user-friendly display. 1990 NSSL researchers begin development of the Warning Decision Support System (WDSS) designed to enhance National Weather Service warning capabilities. 1988 Engineers convert the Cimarron radar to dual-polarization. 1987 NSSL develops and tests radar algorithms that detect and notify forecasters of hail, tornado circulations, downbursts and gust fronts. They discover this capability provides valuable information about the type and amount of precipitation that is falling and call it dual-polarization technology. 1985 NSSL researchers develop and test a technology that transmits radar energy pulses both horizontally and vertically on the Cimarron radar. 1981–1984 NSSL attempts to deploy TOTO, the TOtable Tornado Observatory in the path of an oncoming tornado. Air Force's Air Weather Service, and the Federal Aviation Administration (FAA) to include Doppler capability in their future operational radars. This led to the decision in 1979 by the National Weather Service (NWS), the U.S.

1976 NSSL conducts the Joint Doppler Operational Project (JDOP) to prove that Doppler radar could improve the nation's ability to warn for severe thunderstorms and tornadoes. NSSL engineers develop a color display for Doppler radar data. NSSL's Don Burgess provided storm intercept crews with live radar information via radio-and the term, “nowcaster,” was born. 1975 NSSL's legacy in organized field experiments begins with the Tornado Intercept Project in 1975 led by NSSL's Bob Davies-Jones. This gives NSSL the ability to conduct dual-Doppler experiments by simultaneously scanning the same storm with both radars. Learn more about the Union City tornado and the birth of Doppler weather radar → This same year, NSSL commissions a second Doppler radar 15 miles west of Oklahoma City and names it the Cimarron radar. This important discovery eventually led to NOAA to deploying a nationwide network of Doppler radars. They name this pattern the Tornado Vortex Signature (TVS). Researchers are able to compare the film images with Doppler radar data and discover a pattern that meant the tornado was forming before it appeared on film. The team documents the entire life cycle of the tornado on film. On May 24, an NSSL team intercepts a storm being scanned by the NSSL Doppler radar. 1973 NSSL engineers create a contoured black and white display, a vast improvement from the grid of numbers currently in use. 1971 The experimental NSSL Doppler radar becomes operational. 1969 NSSL obtains a surplus 10 cm Doppler radar that had been used by the U.S. It is the first dual-Doppler experiment in the United States. 1967 Researchers place two Doppler radars so that each has a different view of the same storm. This research led to improved commercial airline safety guidelines in the vicinity of thunderstorms that are still in use today. This data was combined with measurements of the intensity of the rain from the WSR-57 to understand how thunderstorm echoes and turbulence are related. 1965 Aircraft flew into thunderstorms to measure turbulence during Project Rough Rider in the 1960s, '70s and early '80s. The pulsed Doppler radar could receive data in between each transmit pulse, eliminating the need for two antennas and solving the distance problem. In 1964, NSSL engineers modifed this radar to transmit in pulses. This radar was designed to detect very high wind speeds in tornadoes, but could not determine the distance to the tornadoes. In 1956, Cornell Aeronautical Laboratory built a 3 cm continuous wave Doppler radar that used one antenna to transmit and another to receive. 1964 The entire National Severe Storms Project operation moves to Norman and is reorganized as the National Severe Storms Laboratory with Edwin Kessler as the new director. Weather Bureau's National Severe Storms Project (NSSP) moves from Kansas City to the Weather Radar Laboratory in Norman, Oklahoma, and begins work with a recently installed research Weather Surveillance Radar-1957 (WSR-57). Here is a list of the highlights: 1962 A small group of researchers with the U.S. View an interactive, multimedia timeline of NSSL's major accomplishments → NSSL's commitment to improve our knowledge of severe weather and to develop new tools to better forecast and warn of its hazards has endured for more than half a century.
