SGP/EBBR/E19 - Reprocessed and Corrected: Incorrect Net Rad Calibration Coefficient
DataStreams:sgp30baebbrE19.c1
Description:
DATA REPROCESSED and CORRECTED: 

The calibration for negative net radiation was incorrectly entered in the datalogger 
program. The values were reprocessed by multiplying all negative net radiation values by 0.942.

The data were archived February 2017. Please retrieve the reprocessed data for use in your 
analysis.

You may find these data using the ARM Discovery tool at the following link:
http://www.archive.arm.gov/discovery/#v/results/s/finst::ebbr/fsite::sgp/ffac::sgp.E19 

ORIGINAL DQR CATEGORY: Red( Incorrect)

REPROCESSED and CORRECTED DATA ARCHIVED:2017-02

REPROCESS IDENTIFICATION NUMBER: RID 232

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage 
calibration) was incorrect.

Negative net radiations during the subject period can be multiplied by
0.9419 to get corrected net radiation measurements.  The sensible (H)
and latent heat (LE) fluxes (which are very small at night anyway) can
be recalculated using the following equations (where B is Bowen ratio,
Rn is corrected net radiation, and G is soil heat flow):

LE = -(Rn + G)/(B + 1)

H = -(Rn + G + LE)

  • Heat flux, latent, aerodynamic(ale)
  • Heat flux, sensible, aerodynamic(ah)

Description:
The left air temperature, and therefore top and bottom air temperatures
were offscale or incorrect on occasion.  Bowen ratio, sensible heat flux, and latent heat 
flux were also incorrect during those times.

Inspection of the data is required to detect the incorrect periods.

Subject:
SGP Site Power Outage Due to Winter Storm
DataStreams:sgp30baebbrE15.c1, sgp30baebbrE12.c1, sgp30baebbrE13.c1
Description:
On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought 
sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result 
was very very slick roads and mass power outages.
 
The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th.  
The power was restored on 7:56 PM CDT on Wednesday, December 30th
 
Site Emergency procedures were activated and Technicians drained water out of instrument 
reservoirs and other measures as needed, early Monday morning.
 
On Wednesdays as roads and power started was restored to much of the areas east of I-35 , 
Site Technicians performed maintenance on several Extended Facilities.

During this period, data are potentially missing, incorrect, or suspect.  Carefully 
inspect the data before use.
