SGP/SIRS/E27 - Reprocessed and Corrected: Incorrect calibration coefficients
DataStreams:sgpsirsE27.b1, sgpsirs20sE27.a0
Description:
DATA REPROCESSED and CORRECTED: 

The SIRS.E27 data logger reverted to a previous years configuration, possibly due to power 
outage and non-current logger program in storage module. The data were reprocessed to 
apply the correct calibration coefficients for all shortwave measurements.

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

You may find these data using the ARM Discovery tool at the following link:

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


Logger reverted to previous years configuration, possibly due to power outage and 
non-current logger program in storage module.  Note, the tracker had failed during this period as 
well.

The configurations are as follows:
Correct S/N and coefficients for this station during this time

PSP-DS:      104.15 W/(m^2*mV)

Data must be reprocessed for all shortwave instruments; longwave instruments are 
unaffected.  The following corrections must be applied:

down_short_diffuse_hemisp(new) = down_short_diffuse_hemisp(old) * 118.49/111.68
up_short_hemisp(new) = up_short_hemisp(old) * 116.66/111.85
short_direct_normal(new) = short_direct_normal(old) * 123.30 / 111.03
down_short_hemisp(new) = down_short_hemisp(old) * 128.92 / 104.15
