MAO/SKYRAD/M1 - Reprocessed: IRT configuration error

SKYRAD IRT sky temperature measurements were ~40K too low. The analog output configuration 
of the IRT was automatically set to incorrect values by the serial collection script. An 
error in the name of the startup file was corrected.

The data were reprocessed to correct the configuration/calibration and the reprocessed 
data were archived in February, 2014.

• sky_ir_temp_max
• Temperature, Sky Infra-Red(sky_ir_temp)
• sky_ir_temp_min

MAO/MET/M1 - ORG data incorrect

Optical rain gauge (ORG) precipitation values were incorrect the specified time due to a 
wiring problem.

• org_precip_rate_min
• org_precip_rate_max
• org_precip_rate_std
• ORG precipitation rate mean(org_precip_rate_mean)

See below for details of reprocessing that was completed on 20140304.  Original 
DQR category: 3 (Yellow, Suspect).

The netcdf files split routinely due to a bug in the ingest. The ingest has been corrected 
and re-released to production. Data will be reprocessed.

MAO/MET/M1 - Missing pressure data

Atmospheric pressure data is missing due to power and wiring issues during this time.

• Atmospheric pressure(atmos_pressure)

MAO/MET/M1 - Incorrect relative humidity, vapor pressure, and present weather detector 
data

The relative humidity, vapor pressure, and all data from the PWD are incorrect due to 
power and wiring problems during this time.

• Humidity, relative, at 2-m height, 1-min avg(rh_mean)

MAO/MET/M1 - Optical rain gauge performance problems

Condensation inside the optical rain gauge lenses caused false precipitation to be 
recorded. Sensor replacements also showed signs of false precipitation. User discretion advised.

• org_precip_rate_max
• org_precip_rate_std
• ORG precipitation rate mean(org_precip_rate_mean)

MAO/MET/M1 - Present weather detector power issue

A broken power connection caused incorrect data from the present weather detector during 
this time.

MAO/SKYRAD/M1 - Too great of a difference between hemisp1 and hemisp2

down_long_hemisp difference between hemisp1 and hemisp2 indicates a possible problem with 
one or both of the instruments.

MAO/SKYRAD/M1 - Reprocess: Incorrect calibration coefficients

During the DQR time period, the CR3000 program had correct serial numbers and calibration 
coefficients for the PIR1-DIR and PIR2-DIR datalogger channels:  PIR1 SN34303, 
calibration coefficient K1= 0.247520; PIR2 SN34306, calibration coefficient K1=0.230410.
PIR SN34306 (on sun tracker) was used with K1= 0.247520 on the PIR1-DIR datalogger 
channel; K1=0.230410 should be used for reprocessing to provide correct data for PIR1-DIR 
parameters.
PIR SN34303 (on sun tracker) was used with K1= 0.230410 on the PIR2-DIR datalogger 
channel; K1=0.247520 should be used for reprocessing to provide correct data for PIR2-DIR 
parameters.
