Subject:
SGP/EBBR/E19 - Reprocessed and Corrected: Incorrect Net Rad Calibration Coefficient
DataStreams:sgp30baebbrE19.c1, sgp5ebbrE19.b1, sgp30ebbrE19.b1
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.

--- 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)
