NSA/CMH/C2 - Temp and DP have spikes
DataStreams:nsacmhC2.00, nsacmhC2.a1
Description:
During the time periods indicated, the temperature
and dew point data contain spikes.  This usually
meant the first record had 99.99 meaning missing,
but sometimes the whole record was bad.

NSA/CMH/C2 - Some RH Values incorrect
DataStreams:nsacmhC2.00, nsacmhC2.a1
Description:
During the time period indicated, RH values were off by
a factor of 10 (decimal shifted to the left one place)
whenever temp, dew point or both were between 1 deg and
9 deg.  RH was reported as zero whenever temp, dew point
or both were 0 deg or less.  RH values are okay when 
temp and dew point were both 10 deg or above.

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:
  • Total daily accumulated liquid precipitation(precip_total)
  • Precipitation rate(precip_rate)
  • Mean Wind Speed(wspd)
  • Air temperature(air_temp)
  • Instrument enclosure temperature(enclosure_temp)
