SGP/SIRS/E11 - Reprocessed and Corrected: Incorrect calibration coefficients
DataStreams:sgpsirs20sE11.a0, sgpsirsE11.b1
Description:
DATA REPROCESSED and CORRECTED: 

On 11/18/2010 near 00:00 GMT, the calibration coefficients and serial numbers for the SIRS 
program at E11 reverted to the previous year's (2009/2010) installed shortwave 
instruments. Site ops re-loaded the correct program on 11/24. The data were reprocessed to apply 
the correct calibration coefficients for all shortwave instruments.

The data were Archived in August 2016. Please retrieve the reprocessed data for use in 
your analysis.

---------------------------------------------------


Likely near 00:00GMT on 11/18/2010 (Site is missing data from 0000 to 0006 on 11/18) the 
calibration coefficients and serial numbers for the SIRS program at E11 reverted to the 
previous year's(2009/2010) installed shortwave instruments. Site ops re-loaded the correct 
program on 11/24.  Reprocessing will be required for all shortwave instruments.
Incorrect cal coeffs applied during this period:
Diffuse PSP: 113.21 W/(m^2*mV)
PSP-US:      115.00 W/(m^2*mV)
NIP:         115.83 W/(m^2*mV)
PSP-DS:      115.95 W/(m^2*mV)
Correct cal coeffs to apply:
Diffuse PSP: 111.05 W/(m^2*mV)
PSP-US:      115.10 W/(m^2*mV)
NIP:         127.22 W/(m^2*mV)
PSP-DS:      121.20 W/(m^2*mV)

Back out old cal apply new:
Diffuse PSP(down_short_diffuse_hemisp): 111.05/113.21=0.98092
PSP-US(up_short_hemisp):115.10/115.00=1.0010
NIP(short_direct_normal):127.22/115.83=1.09833
PSP-DS(down_short_hemisp): 121.20/115.95=1.0453
