SGP/ECOR/E24 - Reprocess: Sonic analog input failure
DataStreams:sgp30ecorE24.b1
Description:
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/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.

SGP/ECOR/E14 - Flux Measurements Incorrect
DataStreams:sgp30ecorE14.b1
Description:
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.

Reprocessing will not correct this problem; the raw data are corrupted.
Measurements:sgp30ecorE14.b1:
  • mean co2 concentration (c)(mean_c)
  • CO2 flux(fc)
  • Water vapor density (q)(mean_q)
  • average temperature (IGRA internal sensor)(temp_irga)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • h(h)

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/E24 - Water Vapor Density Incorrect
DataStreams:sgp30ecorE24.b1
Description:
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/E14 - Sensor failure
DataStreams:sgp30ecorE14.b1
Description:
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.
Measurements:sgp30ecorE14.b1:
  • Water vapor density (q)(mean_q)

SGP/ECOR/E5 - Incorrect Sensible and Latent Heat Fluxes
DataStreams:sgp30ecorE5.b1
Description:
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.
Measurements:sgp30ecorE5.b1:
  • latent heat flux(lv_e)
  • wT covariance(cvar_wt)
  • rotated covariance wt(cvar_rot_wt)
  • rotated covariance wq(cvar_rot_wq)
  • h(h)
  • covariance wq(cvar_wq)
