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.
