NIM/MET/M1 - Software problem

Intermittent Failure of Logger to read data from the Barometer.

• Atmospheric pressure(atmos_pressure)

NIM/MET/M1  - ORG failure

The optical rain gauge on the met system did not record precipitation during this time 
period.

• ORG precipitation rate mean(org_precip_rate_mean)

FKB/MET/M1 - Optical Rain Gauge Data Incorrect

The optical rain gauge (ORG) data was incorrect during the listed times.  Ice/frost was 
forming on the lenses causing the ORG to believe there was precipitation occurring.

• ORG precipitation rate mean(org_precip_rate_mean)

FKB/MET/M1 - ORG Data incorrect during calibration

The ORG data was incorrect during calibration checks.  The check mimics a precipitation 
event so the precip amounts that were collected were not actually measured.

• ORG precipitation rate mean(org_precip_rate_mean)

FKB/MET/M1 - Incorrect ORG data

Precipitation was being reported on days with no rain.  Problems with the grounding and 
the orientation of the receiver facing south (sunlight in the optics) caused erroneous 
readings.

• ORG precipitation rate mean(org_precip_rate_mean)

FKB/MET/M1 - ORG reporting precip constantly

During the time period listed the ORG reported precip consistently.  Reason unknown as 
deployment ended before resolution of problem.

• ORG precipitation rate mean(org_precip_rate_mean)

NIM/MET/M1 - ORG underestimated precipitation

The ORG underestimated precipitation by about 38% during the entire NIM deployment.  No 
troubleshooting technique or replacement of gauge was successful in correcting the problem.

• ORG precipitation rate mean(org_precip_rate_mean)

PYE/MET/M1 - Wind Speed data contain offset due to induced voltage

The marine model of the RM Young wind sensor needs twisted pair shielded cable.  The 
manufacturer did not originally supply the pigtail with twisted pair shielded cable.  Use of 
twisted pair shielded cable for the rest of the cable run to the logger was also not 
specified.  This caused an induced voltage in the wind speed line from the wind direction 
excitation.  The induced voltage varied from sensor to sensor and probably changed anytime 
the cable was replaced or parts of the wind sensor were repaired or replaced. The induced 
voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s.

HFE/MET/M1 - Intermittent barometer failure

Intermittent barometer failure occurred throughout the deployment.  We were unable to 
pinpoint the cause of the failure.  Typically one or two minutes of missing data occurred 
every few days.

Since pressure data is typically invariant over 1 minute, linear interpolation should be 
fine to fill in missing data.

• Atmospheric pressure(atmos_pressure)

HFE/MET/M1 - Intermittent PWD data

The Present Weather Detector had intermittent missing values throughout this deployment.  
Missing values occurred almost everyday, usually just one or two minutes per day.

The ORG was measuring consistent values for long periods of time.  Typically this is 
indicative of fog, ice crystals in the air or poor performance of the lens heaters.

• ORG precipitation rate mean(org_precip_rate_mean)

HFE/MET/M1 - Induced voltage on wind speed sensor cable

The cable for the wind monitor is not a twisted pair shielded cable.  This caused an 
induced voltage on the wind sensor wires from the wind direction measurement excitation 
voltage.  A small offset is added into the wind speeds.  This value varies.  Most frequently 
the values of 0.49, 0.588 and 0.686 m/s were added into the wind speed.  On 11/27/2008 the 
value jumped to 0.98 m/s for most of the day.

facility ceased 10/1/2009.

• Corrected total precipitation measured by TBRG(tbrg_precip_total_corr)
• tbrg_precip_total

NIM/MET/M1 - PWD cumulative precipitation incorrect

The Present Weather Detector is a serial sensor.  The MET system datalogger reads in the 
data from this sensor.  During the time in question serial comms problems were causing the 
data from the sensor to be read incorrectly.  The data for one variable showed up in 
data for another variable or not at all.  We reprocessed the data to correct as much of this 
error as we could.  The cumulative rainfall variable was calculated from the 
instantaneous rainfall variable during reprocessing.  Since we cannot be entirely sure all 
cumulative rainfall values are correct or were completely captured the cumulative rainfall data is 
considered to be unreliable.  This issue shows up when comparing the cumulative rainfall 
data at the end of the day 07/31/2006 (79.08) and the beginning of the next day 
08/01/2006 (3.17).  Clearly we were either under or over-estimating the cumulative rainfall.

NIM/MET/M1 - PWD 1 minute rainfall data suspect

The Present Weather Detector is a serial sensor.  The MET system datalogger reads in the 
data from this sensor.  During the time in question serial comms problems were causing the 
data from the sensor to be read incorrectly.  The data for one variable showed up in 
data for another variable or not at all.  We reprocessed the data to correct as much of this 
error as we could. We cannot be entirely certain that all rainfall values are correct or 
were captured properly.  It is possible that some values were missed completely.

data was falsely indicating nearly constant precipitation. Later it was falsely reporting no 
precipitation during a large rain event.

Data are not recoverable.

SGP Site Power Outage Due to Winter Storm

On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought 
sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result 
was very very slick roads and mass power outages.
 
The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th.  
The power was restored on 7:56 PM CDT on Wednesday, December 30th
 
Site Emergency procedures were activated and Technicians drained water out of instrument 
reservoirs and other measures as needed, early Monday morning.
 
On Wednesdays as roads and power started was restored to much of the areas east of I-35 , 
Site Technicians performed maintenance on several Extended Facilities.

During this period, data are potentially missing, incorrect, or suspect.  Carefully 
inspect the data before use.
