Subject:
NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:nsasondewnpnC1.b1
Description:
The output precision of the following variables was increased 20060929:

   alt	changed from 1m to 0.1m
   dp	changed from 0.1degC to 0.01degC
   pres changed from 0.1 hPa to 0.01 hPa
   RH	changed from 1%RH to 0.01%RH
   tdry changed from .1degC to 0.01degC

Note that the increase in precision does not necessarily imply an increase
in accuracy.  Users are cautioned to continue to use their best scientific
judgement when using these or any other data.
Measurements:nsasondewnpnC1.b1:
  • alt
  • Dry Bulb Temperature(tdry)
  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)

NSA/MET/C1 - CMH offline
DataStreams:nsametC1.b1
Description:
Beginning 1/24/2011, the CMH went offline resulting in missing temperature and dewpoint 
measurements and erroneous vapor pressure, saturation vapor pressure, and RH measurements. 

Problem fixed with a power cycle.

NSA/MET/C1 - Wind sensor data missing
DataStreams:nsametC1.b1, nsatwrC1.b1
Description:
2m, 10m, 20m wind sensors went off-line 5/17 due to GFCI tripping caused by failing CMH.   
The 2m and 20m data wind sensor returned 6/6, but the 10m remained offline until 7/20 as 
the sensor was damaged.
Measurements:nsametC1.b1:
  • Wind speed, lower, 1-min avg(wspd_arith_mean)
  • Wind speed vector mean(wspd_vec_mean)
  • wdir_vec_std
  • Wind direction, vector, lower, 1-min avg(wdir_vec_mean)

DataStreams:nsametC1.b1
Description:
CMH lost communication with datalogger. All values from CMH were -6999 during this time 
resulting in the CMHRH flatlining at 100%. Communications was intermittent during entire 
time period.

NSA/MET/C1 - CMH failure
DataStreams:nsametC1.b1
Description:
Starting 14:17 GMT on 12/4/2011 the CMH Dew Point began reporting missing value, CMH 
relative humidity was flat-lining at 100% and CMH saturated vapor pressure was flat-lined at a 
high value.  This condition continued very intermittently for several months.  Issue was 
frosting and a failed ventilation fan.
