Description: | DQR No: Platform: rwpwinds (a0, a1, a2) Subject: Data from east and west beams of 915 rwp probably bad Date Submitted: 7 Nov 95 Submitted By: R. L. Coulter _x__ Instrument Mentor ___ EST Member _x__ Science Team Member ___ Other _____________________________ For questions or problems, please contact the ARM Experiment Center at 509-375-6898 or via email at dqr@arm.gov. Platform/Measurement: What level data: (raw,a0,a1,b1,c1 etc): a0,a1,a2 What location was the data collected at: Central Facility Period of time in question Begin Date 10/28/95 Time 00:00 (GMT) End Date ??/??/?? Time ??:?? (GMT) Data should be labeled: _x__ questionable ___ All data fields affected ___ incorrect _x__ Only some data fields affected ___ wrong calibration ___ others Discussion of Problem: The phase shifter for the profiler may be defunct, presently affecting the east and west tilted beams. This affects the resultant speed and direction by biasing them toward north and south directions because the spectra from the east and west directions are noisy and ill defined. The temperatures from the RASS, vertical velocities, and north and south beams are still ok although further degradation may occur. Also the maximum height is significantly reduced. Other observations/measurements impacted by this problem: Suggested Corrections of the Problem: (e.g. change calibration factor and recompute, flag data with this comment, etc.) Fix the phase shifter.
