ENA/SKYRAD/C1 - Intermittent differences between PIRs

Intermittent increased differences between PIR1 and PIR2 during the affected time period. 
hemisp2 data suspect during this period.

ENA/MET/C1 - Optical rain gauge false precipitation

Routine cleaning caused incorrect precipitation to be recorded by the optical rain gauge.

• ORG precipitation rate mean(org_precip_rate_mean)

ENA/MET/C1 - Present weather detector false 1 minute visibility

One minute visibility values are suspected to be false during the indicated times due to 
routine cleaning.

• PWD 1 minute mean visibility(pwd_mean_vis_1min)

ENA/MET/C1 - Ventilator maintenance

Data are incorrect during this time due to ventilator maintenance.

• Vapor pressure mean, calculated(vapor_pressure_mean)
• Humidity, relative, at 2-m height, 1-min avg(rh_mean)
• vapor_pressure_std
• rh_std

• temp_std

ENA/MET/C1 -  Reprocessed and Corrected: Wind direction off by 180 degrees

DATA REPROCESSED and CORRECTED: 

The wind sensor was not aligned correctly. Wind directions during this time are off by 180 
degrees. The raw data were modified and the data were run through the ingest to address 
the issue.

The data were Archived in July 2016. Please retrieve the reprocessed data for use in your 
analysis.

REPROCESS IDENTIFICATION NUMBER: RID 1424

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

The wind sensor was not aligned correctly. Wind directions during this time are off by 180 
degrees.

• Wind direction vector mean(wdir_vec_mean)

ENA/MET/C1 - Optical rain gauge precipitation test

Precipitation recorded by the optical rain gauge during this time is incorrect. Response 
to precipitation was being tested.

• ORG precipitation rate mean(org_precip_rate_mean)

ENA/MET/C1 - Optical rain gauge error

During these times the optical rain gauge malfunctioned and recorded invalid 
precipitation. Sensor was replaced.

• ORG precipitation rate mean(org_precip_rate_mean)

ENA/C1 - Reprocess: Slightly incorrect location fields

Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;
ENA  alt = 30.48 ;

• East longitude(lon)
• North latitude(lat)
• Altitude above mean sea level(alt)

• Altitude above mean sea level(alt)
• North latitude(lat)
• East longitude(lon)

• North latitude(lat)
• East longitude(lon)
• Altitude above mean sea level(alt)

ENA/MET/C1 - Aspirator wire broken

A broken wire on the temperature/relative humidity aspirator caused the fan to stop 
working. Measurements do not appear to be affected.

• Vapor pressure mean, calculated(vapor_pressure_mean)
• Humidity, relative, at 2-m height, 1-min avg(rh_mean)
• vapor_pressure_std
