Subject:
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.
Measurements:sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry bulb temperature(tdry)
  • Relative humidity inside the instrument enclosure(rh)
  • Retrieved pressure profile(pres)
  • Dummy altitude for Zeb(alt)

Subject:
SGP/EBBR/E20 - Wind Direction Incorrect
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The wind direction differed from the co-located SMOS by 50 deg during part of the stated 
period and the electronics had failed completely resulting in a constant 135 degrees for 
the following dates and times:
08/15 0230-0430, 0830-1530 and 09/03 0200-0300, 0500 - 09/10 2230.

Sensible and latent heat fluxes were not affected by this problem.
