QUALITY COLOR: Red - Incorrect PRB REVIEWED: Y ---------------------------------------- DQR DESCRIPTION: Measured downwelling shortwave data was very questionable, reporting nighttime values as low as -50 W/m^2, while differing from calculated downwelling shortwave by as much as 50 W/m^2 lower during the day. The first indication of a problem was around 10 UTC, 9/14, when measured DS values suddenly dropped below 10 W/m^2 for about a 2 hour period before sunrise, then were consistently lower than calculated DS by as much as 40 W/m^2 during the day. The problem got progressively worse with time until the ventilator fan was replace on 9/25. Ventilator fan failure changed the fundamental operating characteristics of this PSP and resulted in unpredictable biased measurements which cannot be corrected without additional empirical characterization of the radiometer in question. ---------------------------------------- DQR DATASTREAM(S): sgpsirs20sE2.a0 inst_global sgpsirsE2.00 Raw data stream - documentation not supported sgpsirsE2.b1 down_short_hemisp down_short_hemisp_max down_short_hemisp_min down_short_hemisp_std START DATE/TIME: 09/14/2003 10:00 GMT END DATE/TIME:09/25/2003 15:43 GMT ---------------------------------------- LINK(S): DQPR: DQPR 131
DQR ID: D031009.2 DQR SUBMITTER: Peter Gotseff DATE SUBMITTED: 10-13-2003 DQR SUBJECT: SGP/SIRS/E21 - Incorrect PIR/UIR Calibration Coefficient SUGGESTIONS: Correct data as described. QUALITY COLOR: Yellow - Suspect PRB REVIEWED: Y ---------------------------------------- DQR DESCRIPTION: Incorrect coefficients were applied to the upwelling longwave radiation measurement instrument (i.e. pyrgeometer, SIRS acroynm "UIR") during this time period. For a PIR mounted in an upwelling measurement orientation (UIR), the thermopile output is extremely low compared to a downwelling PIR (DIR). In addition, the UIR case and dome temperature differences are much smaller than a DIR. This results in the pyrgeometer receiver radiation term, Wr (NREL/Hickey equation) or Wc (Albrecht/Cox equation), dominating all other terms of the infrared radiant flux equation. Since the receiver radiation term uses coefficients in both forms of the pyrgeometer equations nearly equal to 1.0 +- <1% the result is a measurement of incoming longwave radiant flux relatively insensitive to the installed instrument - so long as it is an Eppley PIR. Evaluation of the problem data shows the expected error of the data (before correction) will be within 1% - less than the uncertainty of the instrument (Eppley PIR greater of 5% or 5 W/m2) To correct the one minute data found in the a1 or b1 datastream follow this procedure: 1) Obtain the following variables from the b1 datafile: inst_up_long_dome_temp inst_up_long_case_temp up_long_netir 2) For each one minute data entry in b1 tpUIR[uV] = up_long_netir[uV]/0.2523876[W/m2/uV] 3) Apply for each one minute data entry: WinUIR(W/m2)=k*V+ Sigma*Tc^4 -4*Sigma*(Td^4 - Tc^4) =[0.28902*tpUIR]+[Sigma*inst_up_long_case_temp^4] -[4*Sigma*(inst_up_long_dome_temp^4-inst_up_long_case^4)] where, Sigma = 5.6697E-8 (Stefan-Boltzman Const) Other datastream corrections that use the UIR measurements will require similar corrections.

QUALITY COLOR: Red - Incorrect PRB REVIEWED: Y ---------------------------------------- DQR DESCRIPTION: There were large differences between the measured downwelling shortwave (DS) and the downwelling shortwave calculated from direct (NIP) and diffuse (DD) readings. It appears that the direct normal shortwave readings were much too low, particularly on 7/14 and 7/15. It appears that the diffuse instrument was being shaded properly, but the NIP was not tracking the sun. The problem was corrected during the preventative maintenance visit on 7/16/03 at 1840GMT. The technician reported doing the quarterly connection corrosion checks and ventilator fan cleaning, the NIP was described as having "dry-light dust" on the window, no mention of tracker alignment was made. Although uncertain, a bad connection at some point in the instrument wiring was likely to blame and was eliminated during the corrosion inspection process. ---------------------------------------- DQR DATASTREAM(S): sgpsirs20sE5.a0 inst_direct_normal sgpsirsE5.00 Raw data stream - documentation not supported sgpsirsE5.b1 short_direct_normal short_direct_normal_max short_direct_normal_min short_direct_normal_std START DATE/TIME: 07/11/2003 16:30 GMT END DATE/TIME:07/16/2003 18:40 GMT ---------------------------------------- LINK(S): DQPR: DQPR 86
