T-REX: NWS Six Second Radiosonde Data

Summary

This is one of the upper air data sets developed for the Terrain-induced Rotor Experiment (T-REX) project. This data set includes 457 high vertical resolution (6-second) soundings from 4 National Weather Service (NWS) rawinsonde stations in the T-REX region (Oakland and San Diego, CA and Desert Rock and Reno, NV) for the period 01 March 2005 to 30 April 2005. The soundings were typically released twice per day (0000 and 1200 UTC). The Desert Rock, NV station typically did not do releases on Saturdays or Sundays.
