SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:sgpsondewnpnC1.b1
Description:
The output precision of the following variables was increased 20060928

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.

SGP/MWR/C1 - Increased noise in 31.4 GHz channel
DataStreams:sgpmwrlosC1.b1, sgpmwrtipC1.a1
Description:
The 31.4 GHz channel has been showing an increased level of noise which results in 
increased noise in the LWP retrievals. The instrument is tipping and all other parameters seem 
to be in the range. The elevate noise started in May, but it seems to have become slightly 
worse after summer. After November the noise level seems to have gone back to normal.
Measurements:sgpmwrtipC1.a1:
  • Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
  • 31.4 GHz sky brightness temperature derived from tip curve(tbsky31tip)
sgpmwrlosC1.b1:
  • Sky brightness temperature at 31.4 GHz(tbsky31)
  • Averaged total liquid water along LOS path(liq)

SGP/SMOS/E13 - SMOS T/RH probe solar shield missing
DataStreams:sgp1440smosE13.b1, sgp1smosE13.b1, sgp30smosE13.b1
Description:
The solar shield protecting the T/RH probe from direct sunlight and the elements became 
unscrewed and fell off.  The probe was affected by sunlight and did not have a consistent 
aspiration during this time.
