SGP/MFRSR/E4 - Data not quality assured

Data from October 1, 1999 through March 2001 from MFRSR.E4 should be used with caution. 
During this time period only minimal quality control and maintenance were provided to the 
SGP extended facility MFRSRs because these data were considered to be of questionable 
value under the best of circumstances. That decision was reversed in 2001 when Joe Michalsky 
identified a means to make the MFRSR data scientifically useable.

In the interim, the MFRSRs developed problems with shading, leveling, calibration and 
all-out hardware failures and the stock of spare MFRSRs was depleted and not replenished. 
Most of the shading and leveling problems have now been corrected in the field as well as 
possible, but almost all of the extended facilty MFRSRs still need to be recalibrated or 
replaced.

SGP/MFRSR/E4 - Intermittent Data Logger Failure

Intermittently the data logger for this instrument has suffered failures resulting in loss 
of data for a hour or more at a time as well as saturation of the signal resulting in 
erroneous spikes in the data. The remainder of the data is believed to be okay.

SGP/MFRSR/E4 - Bad head temp and voltage data

Detector voltage and head temperature were erratic and at times wholly incorrect.  The 
first sign of this is on 20040524 just after 2000 UTC.  Sporadic irregularities are not 
altogether unusual, so by itself this is an incident of not much concern.  As time went on, 
however, the erratic readings become more frequent and the head temperature began to be 
affected as well.  Ultimately the problem was traced to a faulty signal cable.

The cable was replaced on 20050921 and the head temperature immediately responded with 
normal readings.  The voltage was still a little noisy for a few days, but ultimately reads 
near constant as expected.  Not sure why the voltage was still noisy for those days, but 
it could either be within normal bounds for this instrument, or possibly the new cable 
wasn't making a good connection at first.

The good news is the mentor believes the irradiance data during the time covered by this 
DQR are good, so this issue should be essentially transparent to the data user.

SGP/MFRSR/E4 - Erratic head temp and missing irradiance data

This problem started out with erratic/low head temperature, and expanded to include 
missing irradiance data.  Maintenance on 8/24 had the unexpected result of causing channels 870 
and 940 to flat line.  The 8/24 maintenance did not fix the head temp problem.  On 9/21 
maintenance fixed the temp and irradiance issue.

Notwithstanding the low head temps, the irradiance data (when available) look OK.  
However, because the instrument is calibrated and designed to run with temps around 40, be 
cautious about using data covered by this DQR.
