Subject:	TWP/C2 Installation
DataStreams:	twpmfrsrC2.00, twpmfrsrC2.a0, twpmfrsrC2.a1, twpmfrsrC2.b1
Description:	The Nauru ARCS was installed during the period September-November 1998. Data were being collected by the end of October, but for the first several weeks of November, the site was undergoing considerable change, so data from that period should be used with caution. The official site dedication occured on November 20. Most on-site activity ended following the dedication so we will consider November 20 to be the beginning of the Nauru operations. The last members of the installation team left Nauru on November 24.

Subject:	TWP/MFRSR/C2 - 415nm channel unstable
DataStreams:	twpmfrsrC2.a0, twpmfrsrC2.b1
Description:	The MFRSR 415nm channel is unstable during this timeperiod. The variables in all versions of data associated with this channel intermittently may be either missing or the values may be too low.

Subject:	TWP/MFRSR/C2 - Shadowband Misalignment
DataStreams:	twpmfrsrC2.00, twpmfrsrC2.a0, twpmfrsrC2.b1, twpmfrsrlangleyC2.c1, twpmfrsrlangplotC2.c1
Description:	During these two periods, there was a shadowband misalignment on the Nauru MFRSR. The shadowband alignment was adjusted several times during this period: on May 17, May 24, June 10, and June 28. The shadowband motor was also replaced on June 28 (all dates 2005). During the flagged periods (May 1-17, June 2-28), the misalignment resulted in significant noise and occasional biases in the direct and diffuse irradiance variables. Optical depths derived from this instrument will also be of poor quality during this period.

DataStreams:	twpmfrsrC2.a0, twpmfrsrC2.b1, twpmfrsrlangleyC2.c1, twpmfrsrlangplotC2.c1
Description:	A shading issue was first noticable in March, likely beginning on or about 3/13. As time progressed it became much worse. Maintenance on 20090520 resolved the problem. The shading got so bad, the mentor suggests avoiding data covered by this DQR.

Subject:	TWP/MFRSR/C2 - Instrument logger problem
DataStreams:	twpmfrsrC2.00, twpmfrsrC2.a0, twpmfrsrC2.b1, twpmfrsrlangleyC2.c1, twpmfrsraod1michC2.c1, twpmfrsrlangplotC2.c1
Description:	The logger was replaced while troubleshooting a prior issue. The replacement logger reports erratic voltages. On 20100122 the instrument stopped functioning, so the problem was likely related to a failing logger. Nonetheless, the irradiance data appear to be OK, so this DQR is being labeled as yellow/suspect.

Subject:	TWP/QCRAD/C1/C2/C3 - error in qc flags
DataStreams:	twpqcrad1longC1.c1, twpqcrad1longC2.c1, twpqcrad1longC3.c1
Description:	In the qc_down_short_diffuse_hemisp field, QC failures from the test indicated by bit_13, "data failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 and SumSW > 50; GSW/SumSW < 0.85 or GSW/SumSW > 1.15)". Solar tracker failures are correctly indicated in the aqc_down_short_diffuse_hemisp field. In the qc_short_direct_normal field, QC failures from the test indicated by bit_10, "data failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 and SumSW > 50; GSW/ SumSW < 0.85 or GSW/SumSW > 1.15)". Solar tracker failures are correctly indicated in the aqc_short_direct_normal field. This is a software problem in the VAP that impacts all dates for which a solar tracker failure occurred prior to 20100608 for each facility. The 20020312 start date was chosen because the DQR system can not link multiple start/end date/times with multiple facilities within the same report. As a result, the latest start date corresponding to C3 was chosen. The actual start dates for which this problem could have occurred for each facility are as follows: C1: 19961010 C2: 19981029 C3: 20020312 Please note that if a solar tracker failure is not indicated by the aqc_down_short_diffuse_hemisp and/or aqc_short_direct_normal fields you can ignore this DQR.

Description:	A grounding problem with the skyrad data logger (discussed in DQR D090605.2) created intermittent anomalous voltages and incorrect data.

Subject:	TWP/MFRSR/C2 - Head not level
DataStreams:	twpmfrsrC2.a0, twpmfrsrC2.b1
Description:	The data from the Nauru MFRSR is questionable because either the cosine correction is bad and/or the head was not level. These problems cause some total optical depths to be below the Rayleigh limit ... obviously something is wrong! The head was checked for level on 1999/05/12 and it was found to be out of level so we do know that 'levelness' has been a problem. We don't yet know if the cosine correction, too, has been a problem. In any event the head was changed on 99/06/19 and the data from this point on looks very good.

Subject:	TWP/MFRSR/C2 - Estimated calibration errors
DataStreams:	twpmfrsrC2.a0, twpmfrsrC2.b1
Description:	The Nauru MFRSR data has been examined for the dates of about 1999/06/21 through 1999/07/22. The head temperature is stable, and there's no sign of shading problems. The calibration stability was examined through the use of Langley regressions, and the calibrations seem stable and reasonably accurate, to wit: wavelength estimated calibration error (negative means MFRSR is too low) 415 -1.6% 500 -1.2% 615 -0.2% 673 -0.6% 870 0.6% 940 don't know but probably with 1-2% Keep in mind that these estimates are from a time period of about 1 month's duration and they could change as we receive more data.
