Description: | DQR No: Platform: EBBR Subject: Stopped Ventilation Fan Date Submitted: 30 August 1994 Submitted By: _x_ Instrument Mentor ___ EST Member ___ 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 (5 minute), a1 (15 and 30 minute) What location was the data collected at: E7, Elk Falls, KS Period of time in question Begin Date 8/9/94 End Date 8/23/94 Time 1922 GMT Data should be labeled: ___ questionable ___ All data fields affected ___ incorrect _x_ Only some data fields affected ___ wrong calibration _x_ others (information only) Discussion of Problem: Sometime between August 9 and 23, 1994 the ventilation fan of the EBBR stopped; the fan guard was clogged with insect remains. The fan was restarted at 1922 GMT on 23 August. Inspection of the EBBR data does not indicate any ill affects on the calculated sensible and latent heat during the period. The fan may have stopped soon before the arrival of the site operator on 23 August. I cannot suggest flagging the data as incorrect, but this message should still be attached to the data so that anyone who might discover something unusual may have some basis for explaining it. The quantities that are normally affected by stoppage of the ventilation to the temperature and relative humidity sensors are: 5 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, and vp_bot 15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l 30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot, bowen, e, h Other observations/measurements impacted by this problem: see list above Suggested Corrections of the Problem: (e.g. change calibration factor and recompute, flag data with this comment, etc.) Enclose the message above with the data if possible.
