Subject:
NSA/METTWR/C1 - 40m wind sensor heater failure
DataStreams:nsamettwr4hC1.b1
Description:
The 40m wind direction became frozen at times.  The values from the sensor were flat-lined 
(stdev = 0) much of the time and did not match sensors from other levels.
Measurements:nsamettwr4hC1.b1:
  • Wind direction, vector-averaged, at 40-m height(WD40M_DU_WVT)
  • WD40M_SDU_WVT

Subject:
NSA/METTWR/C1 - 20m RH Data Questionable
DataStreams:nsamettwr4hC1.b1
Description:
The 20m RH data was questionable at times.  When the data appeared to be poor was when the 
2m and 20m agreed better than the 20m and the 40m and/or 10m.
Measurements:nsamettwr4hC1.b1:
  • DP20M_STD
  • Temperature, dew point, average, at 20-m height(DP20M_AVG)
  • Pressure, vapor, at 20-m height(VP20M_AVG)
  • RH20M_STD
  • Relative humidity, average, at 20-m height(RH20M_AVG)
  • VP20M_STD

Subject:
NSA/TPS/C1 - Reprocess: Incorrect temporal resolution
DataStreams:nsatpsC1.b1
Description:
The data were incorrectly collected and processed at 1 second temporal resolution rather 
than 1 minute resolution.  Data will be reprocessed to average to 1 minute.  Data quality 
are not compromised by this resolution error.
Measurements:nsatpsC1.b1:
  • Precipitation, total daily accumulated(precip_total)
  • enclosure_temp
  • Temperature, air(air_temp)
  • Precipitation rate(precip_rate)
  • Mean Wind Speed(wspd)
