SGP/ECOR/E10 - Timestamp problems and intermittent data gaps

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

SGP/ECOR/E16 - Data suspect due to inability to run QC

Some QC checks were unsuccessful due to a communication failure that resulted in 
contaminated QC field data.

All the data that are based on water vapor density and CO2 concentration are "suspect" 
because many of the standard QC checks were not employed.

(including CO2 flux and latent heat flux) are incorrect for the period of
June 16, 2004, 17:30 to June 30, 2004, 17:30.  Wind and sensible heat flux data are OK.

SGP/ECOR/E24 - Reprocess: Sonic analog input failure

All the data based on H2O and CO2 "analog signals" (latent heat flux, CO2 flux, etc.) are 
incorrect for the period of 10:00 June 4, 2004 to 17:30 Sept. 16, 2004 due to to failure 
in sonic anemometer analog input circuitry.  Correct water vapor density and CO2 
concentration data are stored in IRGA (infrared gas analyzer) raw data files (sgpecorE24.00 
datastream); that data may be used to re-calculate fluxes.

SGP/ECOR/E10 - Sensor failure

Due to sensor failure all the parameters measured by the Infrared Gas Analyzer (water 
vapor density, CO2 concentration, fluxes of latent heat and CO2, etc.) are incorrect for the 
period of 18:30 Oct. 22, 2004 to 22:00 Dec. 14, 2004. The data is irrevocably lost.

SGP/ECOR/E16 - Failed IRGA

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.

The latent heat flux and CO2 flux data are irrevocably lost for the period from Nov. 2, 
2004, 02:00 to Nov. 12, 2004, 18:00.

The sonic anemometer was mounted 90 degrees off during August 26 Corrective Maintenance

SGP/ECOR/E3 - Data transfer problem

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.

SGP/ECOR/E6  - Reprocess: Incorrectly flagged (marked as "bad") H2O/CO2 data

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.

SGP/ECOR/E10 - Reprocess: Incorrect H2O, CO2

Due to failure of analog output circuitry in the Infrared Gas Analyzer (IRGA), CO2 and 
water vapor parameters measured by the IRGA (water vapor density, CO2 concentration, fluxes 
of latent heat and CO2) were incorrectly recorded in sonic raw data files for the period 
of 22:30 Dec. 14, 2004 to 22:00 Jan. 11, 2005. The data could be recovered from IRGA raw

DQR category: 4 (Red, Incorrect).

-----------------------------------------------------------

It was discovered that the E10 ECOR boom is aligned 17 degrees to the west of true north.  
Therefore, all wind direction data for the stated period is 17 degrees too high.  
Subtract 17 degrees from the wind direction to give the correct direction.

The E10 configuration file was modified to correct this problem.

SGP/ECOR/E16 - LI-7500 Pressure and Temperature missing

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.

SGP/ECOR/E5 - Reprocessing Notice (RID 351)

DATA REPROCESSED.  Data was reprocessed on 20160224 to fix issues noted in the original 
DQR copied below.

---------------------------------------------------------------------------

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

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.

• atm_pres

SGP/ECOR/E10 - CO2 and Latent Heat Fluxes Incorrect

The CO2 and latent heat fluxes were incorrect because the sonic anemometer was not working 
properly.

SGP/ECOR/E5 - Flux Measurements Incorrect

The ECOR datastream was corrupted; this happens when the ECOR program produces a 
datastream of the wrong length (i.e., leaves one or more measurements out).

Fluxes and some other measurements are incorrect.

Note: Mentor reports reprocessing will not correct this problem.

The temp_irga was too large 05/09/07 1300 GMT - 05/10/07 2000 GMT.

The temp_irga was flat lined at 49.96 C 05/10/07 2030 GMT - 05/17/07 2000 GMT.  

The temp_irga was missing 05/17/07 2030 GMT - 05/19/07 1700 GMT.

not working.

SGP/ECOR/E24 - Water Vapor Density Incorrect

Mean Water Vapor Density (mean_q) often did not trend well with the co-located SMOS and 
sometimes jumped downwards approximately 200 to 300 mmol/m^3.  Some of the instances were 
clearly a result of contamination by precipitation, but others were not; the latent heat 
flux was sometimes affected.

It was determined that all instances of this behavior from the beginning of 2008 through 
the beginning date of this DQR were caused by precipitation/dew/frost.

SGP/ECOR/E10 - Incorrect CO2 fluxes

The analog CO2 signal from the LI-7500 to the sonic anemometer became very noisy and 
incorrect CO2 fluxes resulted. Sonic anemometer was replaced.

• CO2 flux(fc)

SGP/ECOR/E14 - Sensor failure

The water vapor output of the LI-7500 was too low, indicating that water vapor leaked into 
the sensor and that the chemicals are spent or there was an electronic failure.

Latent heat flux was not normally affected by this problem.

SGP/ECOR/E5 - Incorrect Sensible and Latent Heat Fluxes

Starting at approximately 4:00 GMT on 02/16, the ECOR suffered from the "garbled" data 
condition, a result of a serial communication failure. 

All sensible and latent heat flux measurements are incorrect during this condition.

Pressure and temperature from the LI-7500 are missing. This did not affect the sensible 
and latent heat fluxes, however, much of the ECOR data is missing during this period.

Attempts to correct the problem were unsuccessful until the time of site decommissioning. 
This facility was decommissioned and maintenance efforts ceased 10/1/2009.

SGP/ECOR/E31 - Latent heat and CO2 fluxes incorrect

The analog channels of the CO2/H2O sensor were missing due to a poorly seated connection.  
This results in incorrect fluxes.
