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:
  • Relative humidity inside the instrument enclosure(rh)
  • Dry bulb temperature(tdry)
  • Dummy altitude for Zeb(alt)

NSA/TSI/C1 - frost/condensation in lens
DataStreams:nsatsiskycoverC1.b1, nsatsiskyimageC1.a1
Description:
The sky image appeared hazy and was corrected by cleaning the neutral-density filter and 
lens of the camera. The determination of cloud fraction may be affected.
