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.

SGP/AERI/E14 - Nest on the input port window

On June 23, 2009, a mud dauber nest was found on the input port window of the AERI 
interferometer and was removed. The nest was likely responsible for significant signal loss.  
The nest was estimated to have covered close to 20 percent of the window. While the 
presence of the nest increases signal loss, the measurement values remain valid despite the 
obstruction. The input port obstruction due to the nest was consistent during calibration 
Black Body measurements as well as during sky measurements. The same may not apply during 
nest building or other insect activity within the instrument field of view.

SGP/VCEIL/C1/B4/B5/B6 - Reprocess: Incorrect serial_number and sum_backscatter fields

Attribute serial_number: In most cases, this field is not representative of the actual 
serial number of the instrument because the value did not change when an instrument changed 
locations or was replaced with a spare.

Variable sum_backscatter: An out-of-range condition for the "sum of detected and 
normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 
0.0999 /srad.

This DQR also applies to a1 level data collected prior to b1 level.
