designated WSR/TAMU-1. The TAMU-1 was updated in 1966 to allow dual wavelength operations. After several modifications, the radar was placed on top of the newly completed Eller O&M Building in 1973. More modifications were made in 1989 in anticipation of adding Doppler capability. One of the storms that was tracked with this radar was Hurricane Alicia in 1983. As the storm made landfall, the Galveston NWS office lost its radar. The A&M radar tracked the remnants as they moved inland. The integration of a Lassen Research PSP-32 processor in 1992 enabled Doppler capability. The new system was renamed the TAMU Aggie Doppler Radar (TAMU-ADRAD). This system was updated in 1993. A final upgrade to the pedestal, removal of the side dishes, new processor, and work station occurred in 1997. Starting in October 1998, live radar pictures from the ADRAD were available online during storms. In 2016, ADRAD data became available for use by the National Weather Service offices and research teams through Gibson Ridge Analyst software (GRLevelX). Radar properties The current antenna is a parabolic solid with a 4.88 meter (16 foot) diameter. It is situated 172.5 meters (566 feet) above mean sea level. It rotates at 2.5 RPM (15 degrees per second) or 4.5 RPM maximum (27 degrees per second). Elevation can be set from -1 to 90 degrees. The transmitter is an Enterprise Electronics DWSR-88S, operating on a wavelength of 10.56 cm (corresponding to 2840 MHz). This frequency is in the S band, which is also used by the NEXRAD network. Peak power is 1 megawatt. See also Texas A&M University is also a partner in the Smart-R mobile research radars.
