SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect

Soil Temperature #2 was intermittently incorrect.
The cause is unknown.

The indicated measurements that are calculated using 
soil temperature are also incorrect.

Soil moisture #2 (30 minute only) was also affected 
because version 6 of the EBBR datalogger program 
uses a multiplication of soil temperature and soil 
moisture as part of the adjustment of soil moisture for
soil temperature.  This was discovered to be a poor 
technique soon after it was implemented, but E2 will
continue to use version 6 until a replacement EBBR
unit is available.  When soil temperature #2 is large
negative, soil moisture #2 is often twice as large
as it should be.

EBBR unit changeout dates are listed on the EBBR 
instrument web page.

Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 1, 3, 4, and 5, as follows:

ave_shf = (g1 + g3 + g4 + g5)/4

e = -(q + ave_shf)/(1 + Bowen)

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
