SGP/SIRS/E10 -  Reprocessed and Corrected: Incorrect calibration coefficients

DATA REPROCESSED and CORRECTED: 

Beginning on 03/20/2010 approx. 12:45 GMT the data logger program reverted to its previous 
version. That is, it reverted to the version prior to the latest instrument change out 
on August 18th 2009. Applied calibration coefficients and serial numbers are incorrect 
from 03/20/2010 1245 GMT until correction on 03/24/2010 1645 GMT. 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.

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


Beginning on 3/20/2010 approx 12:45 GMT the datalogger program reverted to its previous 
version. That is, it reverted to the version prior to the latest instrument changeout 
August 18th 2009.  Applied calibration coefficients and serial numbers are incorrect from 
3/20/2010 1245 GMT until correction on 3/24/2010 1645 GMT.  

Longwave instruments are NOT affected. 

The following shortwave datastreams(instrument) are affected:
down_short_hemisp (PSP)
up_short_hemisp (PSP)
short_direct_normal (NIP)
down_short_diffuse(8-48)

Users may apply the following corrections to the data during this time period:
new value = old value * (new cal coeff/old cal coeff)
down_short_diffuse = down_short_diffuse(old) * (114.21/108.53)
up_short_hemisp = up_short_hemisp(old) * (112.93/127.20)
short_direct_normal = short_direct_normal(old) * (116.86/126.60) 
down_short_hemisp = down_short_hemisp(old) * (118.31/127.41)

Data will be reprocessed.
