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)
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)

NSA/MET/C1 - 10m wind data not reporting
DataStreams:nsametC1.b1, nsatwrC1.b1
Description:
10 meter wind speed and direction data were not reporting after a scheduled power outage 
took place.   Sensor was replaced.

  • Wind speed vector mean(wspd_vec_mean)
  • wdir_vec_std
  • Wind direction, vector, lower, 1-min avg(wdir_vec_mean)
nsatwrC1.b1:
  • wdir_vec_std
  • Wind speed, lower, 1-min avg(wspd_arith_mean)
  • Wind direction, vector, lower, 1-min avg(wdir_vec_mean)
