Subject:
SGP/ECOR/E5 - Flux Measurements Incorrect
DataStreams:sgp30ecorE5.b1
Description:
The ECOR datastream was corrupted; this happens when the ECOR program produces a 
datastream of the wrong length (i.e., leaves one or more measurements out).

Fluxes and some other measurements are incorrect.

Note: Mentor reports reprocessing will not correct this problem.
Measurements:sgp30ecorE5.b1:
  • CO2 flux(fc)
  • Latent heat flux(lv_e)
  • Corrected sensible heat flux(h)

SGP/ECOR/E24 - Half Hours of Data Missing
DataStreams:sgp30ecorE24.b1
Description:
Individual half hours of data were missing infrequently because of a UPS
problem.  The extent of missing data is minimal, with only a few to several half hours

Subject:
SGP/CEIL/C1/B4/B5/B6 - Reprocess: Incorrect serial_number and sum_backscatter fields
DataStreams:sgpceilC1.b1
Description:
Attribute serial_number: In most cases, this field is not representative of the actual 
serial number of the instrument because the value did not change when an instrument changed 
locations or was replaced with a spare.

Variable sum_backscatter: An out-of-range condition for the "sum of detected and 
normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 
0.0999 /srad.

This DQR also applies to a1 level data collected prior to b1 level.
Measurements:sgpceilC1.b1:
  • sum_backscatter

SGP/MET/E9 - False tips in high winds
DataStreams:sgpmetE9.b1
Description:
The TBRG's were mounted at a height that made them prone to vibrations caused by high 
winds which may have caused false tips.  The end date of this DQR indicates when the rain 
gauge was lowered to mitigate these effects.  

Effects on the total precipitation amounts are assumed to be negligible.
