| 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.

--- 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.

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 |
