Subject:
SGP/EBBR/E8 - Reprocess: E8 Soil Heat Flow #2 Failure - Replaced
DataStreams:sgp30ebbrE8.b1, sgp15ebbrE8.b1
Description:
Soil heat flow probe #2 values were positive and in the thousands
after an apparently catastrophic failure at 1900 GMT on
11 October 1997.  The probe was replaced on 29 October 1997
at 2010 GMT.

The data affected (and thus incorrect) includes:

15 minute: mv_hft2
30 minute: shf2, c_shf2, g2, ave_shf, e, h.

The latent and sensible heat fluxes can be recalculated by using
only soil heat flows 1 and 3 through 5 to calculate the average
soil heat flow,

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

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

h = -(e + ave_shf + q).
Suggestions: 
Recalculate average soil heat flow (ave_shf) and latent (e) and sensible (h) heat 

fluxes 
using the equations provided.
