Description:
The SGP.C1 AERI system clock was not being regularly checked and synched
with a time server between May 2001 and November 2001.  When the problem
was identified and the clock was corrected, a time offset of 17 minutes
and 2 seconds (slow) was present.

The data available from the ARM Archive have been time corrected
by Dave Turner using a piece-wise linear function based on a comparison
of pressure data from the AERI and SMOS. Dave indicates "this results
in a good fit to the data" and "errors in the reported sample times are
reduced to approximately 1 minute or less.  Given the nominal three minute
averaging period of the AERI, this should suffice for most applications."

Data between 20011019.1615-20011029.1621 did not need to be corrected
due to a series of events that caused the clock to be temporarily
synched and then revert back to the linear drift pattern.

Note, there are three other variables in the AERI data products which
report time: Time, timeHHMMSS and rawTimeHHMMSS.  The data in these
variables were not modified, so these data will not agree with basetime
+ time_offset.

Also note, VAPs which use the AERI data as input were NOT reprocessed.
VAP data during the time period specified are questionable and should
be used with caution.

Subject:
SGP/AERI/C1 - Data Reprocessed to correct laser wavenumber
DataStreams:sgpaeri01ch1C1.a1, sgpaeri01ch2C1.a1
Description:
SGP.C1 AERI data from 20000302-20020510 have been reprocessed
to correct for the spectral calibration; i.e., to correct the
laser wavenumber.  These data are now available from the ARM
Archive.

Data users who retrieved the previous version of this data from 
the archive should consider the following graphic to gauge the
impact the correction might have on their analyses.


vlaser_correction_example.png  

Note: only the ch1 and ch2 data were reprocessed; the summary
data have not been recomputed.  The summary data typically
are 5 to 25 cm-1 spectral averages of the ch1 and ch2 data,
and the effect of the spectral calibration on these averages
should be negligible.
Measurements:sgpaeri01ch1C1.a1:
  • Downwelling radiance interpolated to standard wavenumber scale(mean_rad)

sgpaeri01ch2C1.a1:
  • Downwelling radiance interpolated to standard wavenumber scale(mean_rad)
