SGP/ECOR/E10 - Timestamp problems and intermittent data gaps
DataStreams:sgp30ecorE10.b1, sgpecorE10.00
Description:
The raw files produced by the instrument contained bad (uncorrectable) data.  Specifically 
the date of the data in the file is given a time that is ahead of the actual time the 
data was genertaed.  This was caught because the date in the file was ahead of the system 
time of the server processing the raw file.  The mentor indicated all such files were 
compeltely bad and unrecoverable so all files that failed to be ingested were not shipped to 
the archive, thus producing holes in the raw and processed datastreams.  Because the 
problem was discovered by comparing to system time at time of processing all files between 
these dates should be consider suspect.  Therefore the files that are on the system over 
these three days should be used cautiously

period of 18:30 Oct. 22, 2004 to 22:00 Dec. 14, 2004. The data is irrevocably lost.

SGP/ECOR/E16 - Failed IRGA
DataStreams:sgp30ecorE16.b1
Description:
The infrared gas analyzer (IRGA) failed on Nov. 2, 2004, 02:00; the system continued to 
operate without H2O and CO2 data until Nov. 9, 2004, 15:30; then it stopped due to another 
hardware failure. The system was returned to service on Nov. 12, 2004, 18:00.

2004, 02:00 to Nov. 12, 2004, 18:00.

SGP/ECOR/E3 - Data transfer problem
DataStreams:sgp30ecorE3.b1, sgpecorE3.00
Description:
Serial communication with one sensor (the IRGA) were partially disrupted due to 
deteriorating hardware from 13:53, Dec. 19, 2004 to 09:31 Dec. 20, 2004.  Serial data from the IRGA 
is mainly used to get sensor status codes, so this might lead to false increase of "bad" 
point count.  It seems that IRGA analog outputs (stored in raw sonic data file,  primary 
source of data) were not affected, so the flux data may be reprocessed or verified using 
raw sonic data files and ignoring IRGA sensor status.

Subject:
SGP/ECOR/E24  - Reprocess: Incorrectly flagged (marked as "bad") H2O/CO2 data
DataStreams:sgp30ecorE24.b1
Description:
Due to system clock instability on ECOR computers their system time is adjusted 
approximately once per hour; sometimes this adjustment leads to backward time jumps over midnight, 
into the previous day. In this case all the data based on CO2/H2O measurements might be 
erroneously marked as bad. Below is a list of times when that might have happen.

Description:
The pressure and temperature measurements were not recorded; the LI-7500 serial datastream 
was not being captured by the ECOR system because of a serial port failure.

Some degradation of the latent and sensible heat fluxes may have occurred during high 
summer temperatures.  The error in the fluxes would be no more than 5 to 10% of the 
measurement, still well within the measurement error of the system.
Measurements:sgp30ecorE16.b1:
  • latent heat of vaporization(lv)
  • latent heat flux(lv_e)
  • h(h)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • Retrieved water vapor density profile(rho)
  • average temperature (IGRA internal sensor)(temp_irga)

SGP/ECOR/E5 - Reprocess: Time shifted -7 hours
DataStreams:sgp30ecorE5.b1, sgpecorE5.00
Description:
An inadvertant power outage caused the ECOR program to shut down abnormally.  When power 
was restored, the timestamps on the ECOR files were 7 hours behind the correct time and 
the site ID was not accessed from the ECOR configuration file resulting in site ID (05) 
being replaced with "AN".

These conditions caused the ECOR files to be unrecognizable and therefore are presently 
missing in the Archive.

Correction of the timestamp and ID in the files should allow them to be processed and 
added to the Archive.

SGP/ECOR/E21 - Intermittent incorrect flux measurements
DataStreams:sgp30ecorE21.b1
Description:
At various times during the period, the LI-7500 CO2/H2O serial and analog signals from the 
LI-7500 were missing, but usually not at the same time.

When the CO2/H2O serial datastream was missing, the Pressure and Temperature were missing; 
this did not, in itself, result in incorrect fluxes, as default values for pressure and 
temperature are automatically used.

Fluxes were incorrect when the CO2/H2O analog datastream was missing; these
times are identified by the qc checks.
Measurements:sgp30ecorE21.b1:
  • latent heat flux(lv_e)
  • covariance wc(cvar_wc)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • covariance wq(cvar_wq)
