Subject: | SGP/MFR10M/C1 - Data discontinuities of unknown origin |
DataStreams: | sgpmfr10mC1.00, sgpmfr10mC1.a0, sgpmfr10mC1.b1
|
Description: | There is a discontinuity in the data (all channels) just before 1930 UTC on Jan 20, 2005
and just after 1500 UTC on June 27, 2003. There is nothing unusual in the temp or volt
data. At these times the tower was lowered for cleaning so the initial assumption was the
instrument was dirty, and a cleaning resulted in the discontinuity. This theory doesn't
hold up well though as the tower is lowered for instrument cleaning regularly and these
are the only two times in the past few years that a discontinuity coinciding with a
lowering of the tower has resulted . Down pointing instruments are also not prone to
collecting dust and dirt. This instrument is located on the E13 SIRS tower and the down pointing
PSP does not show a discontinuity at either time, which further discounts the dirty
instrument theory. Site operations were asked to check the instrument mount to see if it was
loose possibly causing the instrument to change its position, and they reported that the
mount seemed secure and stable. So as of now, this issue is a mystery. |

Subject: | SGP/MFR10M/C1 - Dip in data at solar noon |
DataStreams: | sgpmfr10mC1.00, sgpmfr10mC1.a0, sgpmfr10mC1.b1
|
Description: | On clear days there is a dip in the data (all channels) at solar noon that is more
pronounced during the winter months. While we currently don't know the cause of this dip, we
believe it is related to reflections off the tower pole. The working theory says at solar
noon the north-south crossbar shades the tower pole cutting off reflections into the
detector. If true, this means data on either side of the dip are being enhanced by
reflections and the data within the dip are actually "correct." An experiment is being planned
for next fall that will wrap the upper portion of the tower in a non-reflecting cloth.
This should determine if the dip is related to reflections from the tower pole. |

DataStreams: | sgpbrs20sC1.a0, sgpbrsC1.00, sgpbrsC1.b1
|
Description: | Lightening strike on or near 6/2/2004 took the BRS NIP(31747E6) out of service, on or near
6/15 the NIP was replaced and the datalogger program was changed to reflect the new
NIP(31343E6). On 8/5/2004 the DIR (Downwelling longwave) instrument was changed out and a new
program was loaded to reflect a new DIR. The new program contained the original
installed shortwave instrument calibration coefficients including NIP 31747E6. Thus from 8/5 to
when the shortwave instruments were changed out on 12/3 the wrong s/n and calibration
factor (i.e. 31747E6) was applied to the actual NIP(31343E6)installed at BRS C1. |

Subject: | SGP/BRS/C1 - Monthly Summary |
DataStreams: | sgpbrsC1.b1
|
Description: | Data quality this site-month is good. The offset in the Global PSP has been much improved,
with an average nighttime offset of -4 W/m^2, since measures were taken on 17 DEC 2004
to fix it. The Global PSP does not go below nighttime empirical limits all month. Global
does fall below daytime empirical limits for significant time periods on the 2, 4, 5, 12,
28, 30. There were still substantial 3 component flags 17 DEC 2004. The charcteristic
three component failures are present through out the month, especially closer to the end of
the month. The problem is about equally as bad in the morning as the evening.
The flags are usually high level yellow at their worst for any given day. Finally, there
are the typical three component flags on the 29th as well, but these occur under cloudy
skies. The data return to normal the next day and a cause for the problem cannot be
determined. |

Subject: | SGP/BRS/C1 - low downwelling shortwave readings |
DataStreams: | sgpbrs20sC1.a0, sgpbrsC1.00, sgpbrsC1.b1
|
Description: | Downwelling shortwave (DS) values frequently drop below -10 W/m^2 at night, and are
consistently 20-40 W/m^2 less than the calculated downwelling shortwave during the day in
clear-sky conditions. Corrective maintenance on 12/17/2004 corrected this offset. It is not
clear which CM action corrected the problem since the DS instrument cable was grounded to
a new location and the DS ventilator fan was found in poor condition and was replaced.
Either of these issues could have led to the problem observed in this instrument. |

Description: | The interferometer of the sgpE14 AERI system began to fail around 1 Aug 2007. In this
period of time, the interferometer was occasionally 'losing a fringe' and thus introducing
phase shift errors into the data. After this happened a number of times, the
interferometer would lock up and no data could be collected until site operations reset the instrument.
Not all of the data collected during this period are bad (only the samples that were
affected by a phase shift -- about 10% to 25% of data collected each month during the period
were bad) while the rest of the data is of good quality.
The instrument mentor has created Data Quality files that users can use to identify these
bad samples and exclude them from their analysis. Thus, the data for this period are
coded "suspect", because the lion's share of points are actually good but there is a fair
number of samples that are bad and should not be used. |

Subject: | SGP/MFR10m/C1 - Small intermittent time stamp error |
DataStreams: | sgpmfr10mC1.a0, sgpmfr10mC1.b1
|
Description: | The internal code that runs the MFR data logger had a bug that occasionally caused the
time stamp associated with the data to be slightly in error. This error is thought to be
very small (say less than 30 seconds) and very infrequent. (Unfortunately, we cannot give
firm estimates of the magnitude and frequency of the error).
Also, the upwelling MFR measurements were contaminated by electrical noise originating
from the heater contained in the sensor head. During the time the sensor head was polled by
the data logger, the heater would strobe "on and off", and the noise caused by this
strobing could greatly contaminate the data. Some of the data is so contaminated that it is
virtually useless.
After 96/03/27 these problems were corrected. Those who use the data before this time
should realize that the time stamp for each record of data might be slightly in error, and
the data could be very noisy due to the heater switching on and off. |

Subject: | SGP/MFR10M/C1 - Corrupt or truncated data |
DataStreams: | sgpmfr10mC1.a0, sgpmfr10mC1.b1
|
Description: | On about 96/08/18, the data logger board for the downlooking 10m MFR was modified to test
an upgrade. Unfortunately this upgrade did not work as planned, and some data was either
corrupted or truncated. You can't miss the corrupted data (from which you can infer
albedos much greater than one!). The truncated data is truncated in time, by which we mean
that only a half day's worth of data was collected. The daily time span of these
truncated data is from midnight to about 1 PM (local time). At about 96/10/03, these problems
were corrected.
Note: The "begin date" given for this DQR may be off a day or two, so beware. |
