SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry

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.

NSA/MFRSR/C2 - Instrument shading problem

There is a slight shading issue occurring between 1230 UTC and 1730 UTC.  It is first 
noticed around 6/1/2007 and is very slight.  It is last noticed on 8/10/2007.  This DQR runs 
through 8/31/2007 since the rest of the month is cloudy and it is hard to determine when 
the shading issue stopped.
