SGP/SMOS/E13 - Sensor failure

Beginning around 1415 UTC on 08/30, the RH readings for
this instrument were frequently around 0 (sometimes
there are erratic spikes upward from 0 for periods of
time). Rainfall appears to have been the cause of the
erroneous readings, as the instrument appeared to fail
in and around the time of heavy rains.

A maintenance visit occurred on 09/04, afterwards data
returned to normal values.

SGP/SMOS/E21 - Wind Monitor Impacting Bird Spikes

The wind direction is flatlining and wind speed occasionally does not compare well with 
co-located ECOR.  Problems with the height of the mount caused the vane to impact the bird 
deterrent spikes and "catch".  Symptoms appear as winds coming out of a 255 to 270 
direction for long period of times.  The wind speed values are also affected as the wind 
monitor is no longer normal to the wind direction.

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 - Reprocess: Time shifted -7 hours

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.

• covariance wc(cvar_wc)

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.

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.
