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/E27 - Multiplexer #2 failure
DataStreams:	sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:	A problem with the #2 Multiplexer caused a large number of measurements to be incorrect. Sensible and latent heat fluxes were often affected.

Subject:	SGP/EBBR/E27 - Measurements offscale
DataStreams:	sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:	All J-panel 4 measurements (soil heat flows, net radiation, air temperatures, home signals, pressure, vapor pressure) were sometimes offscale or otherwise incorrect. J-Panel was replaced 20080326 correcting the problem.
