1994 VORTEX KTLX WSR-88D Level II Radar Data [NCDC]


This data set contains Level-II WSR-88D radar data from the Twin Lakes, OK (KTLX) site in central Oklahoma (35.33N and 97.278W) during periods the South Dakota School of Mines and Technology (SDSMT) T-28 aircraft flew for the Verification of the Origins of Rotation in Tornadoes EXperiment - 1994 (VORTEX94) field project. Data are included for the following periods:

6 May 1994: 2105-2354 UTC
9 May 1994: 1646-1959 UTC
23 May 1994: 2101-2355 UTC
24 May 1994: 1300-1456 UTC
25 May 1994: 2245-2355 UTC
26 May 1994: 0001-0157 UTC
29 May 1994: 1205-1517 UTC

The NEXRAD Level II data are the three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. Depending on the volume coverage pattern in use, the data resolution varies (five, six or ten minutes). A data file consists of a 24 byte volume scan header record followed by numerous 2432 byte base data and message records.
