SGP/EBBR/E7 - Reprocess: Soil Temperature Probe Failure

Failure of soil temperature probe #4 at E7, Elk Falls, KS resulted in incorrect
data values for 6 fields for the period of time listed above.  The soil
temperature value from probe #4 went offscale, resulting in a zero value
for the soil energy storage term calculated from that probe and thus no
contribution to the total soil heat flux for soils set 4 and the same for
average soil heat flux.  This led to incorrect sensible and latent heat
flux values.

The fields affected were:

30 minute: ts4, ces4, g4, ave_shf, e, h

15 minute: rr_ts4.

Soil temperature probe #4 was replaced at 1638 GMT on June 29.  Old S/N
92045, new S/N 92054.  Sensible and latent heat fluxes can be recomputed by
averaging the soil heat flux from the four sets of functioning soil probes;
use the following equations:

ave_shf = (g1 + g2 + g3 + g5)/4

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

h = e * bowen,

where g is total soil heat flow, q is net radiation, and bowen is Bowen Ratio.
