SGP/EBBR/E13 - Annual Calibration changeout

On May 24, 1996 the changeout for annual calibration occurred at E13,
Central Facility, OK.  Between 1800 and 2130 GMT no data was remotely collected.
Furthermore, 5 minute data inbetween 1800 and 2130 is incorrect, 15 minute data 
between 1800 and 2130 is incorrect, and 30 minute data for 2130 GMT is 
incorrect.  A large jump in soil moisture appears in the data after the 
installation was completed (the soil bags holding the probes had a greater 
than ambient soil moisture).  Soil measurements indicated greater than ambient 
soil moisture until a rain just after 0600 GMT on 1 June saturated the soil; 
after this period the probes reflected actual soil moisture conditions.  

The larger than normal soil moistures have some impact on the soil heat flux 
during this time of year, and thus soil heat flux from the soil flow plates 
and soil temperature probes, as well as average soil heat flux, computed 
sensible and latent heat fluxes; these quantities should be considered to 
be incorrect from 24 June at 2130 GMT until about 1200 GMT on June 1.

Because of communication problems, data is missing from the time of the 
EBBR installation until 29 May 1996 at about 1815 GMT.  This data may be 
recovered from the sneakernetted data set.
