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/SWATS/E7 - Sensor failure, 35cm E
DataStreams:sgpswatsE7.b1
Description:
The 35-cm East sensor had several problems before failing permanently in 2007:

20061208.2000-20070306.2000: temperature rise reported values of -9999, and soil 
temperature reported abnormally high temperature values.  

20070813.1200-20070912.1300: all variables reported as -9999, including soil temperature.  
A very small number of soil temperature values were reported as unusually high 
temperature values after 09/10/07.

20070912.1300-20070915.1600:  incorrect values of temperature rise reported (near 0 C), 
and soil temperature values incorrect and unusually high.

20071110.0000-20071115.2300:  incorrect values of temperature rise reported near 0 C or 
unusually low.  Values of soil temperature OK.  

20071128.0000-->:  Except for two very brief recoveries (on the order of a few days), all 
35cm E variables are reported as -9999.

SGP/SWATS/E10 - Sensor failure, 15cm E
DataStreams:sgpswatsE10.b1
Description:
The 15cm E sensor failed at 7:00 GMT on 06/02/2002. Values of temperature rise from this 
sensor often do not fail automated QC tests, but inspection of the time series reveals 
that the values are incorrect. Since 2002, this sensor has alternated between providing 
temperature rise values near 0 C, equal to -9999, or other obviously incorrect values. 

Soil temperature data are not affected.

SGP/SWATS/E13 - Lightning damage
DataStreams:sgpswatsE13.b1
Description:
After a lightning strike near the CF, the SWATS trise values were reporting near zero. The 
current channel in the CE8 module failed, so the wire was moved to the next channel and 
trise values returned to normal.

There are no soil moisture data available during this time period.
