Description:
The output precision of the following variables was increased 20060929:

   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

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 and erroneous vapor pressure, saturation vapor pressure, and RH measurements. 

Problem fixed with a power cycle.

the sensor was damaged.

corresponding to the datastreams (down_short_hemisp, down_short_diffuse_hemisp, 
short_direct_normal) but the calibration coefficients weren't changed until 07/25/2011 1842GMT.  
Data will be reprocessed.

Longwave data are unaffected.
