SGP/EBBR/E20 - Reprocess: E20 Soil Probes #3 Cables Cut
DataStreams:sgp30ebbrE20.b1, sgp15ebbrE20.b1
Description:
The cables going to #3 soil temperature, moisture, and heat flow probes 
were cut by a mower on 11 June 1997 and were repaired on 16 July 1997.  
Data for the temperature probe was offscale, for the soil moisture probe 
was a constant 10.1 (close to the actual), and for the soil heat flow 
was large negative during the period. 

The following are the data quantities that were affected:

15 minute: rr_ts3, mv_hft3, r_sm3

30 minute: ts3, ces3, shf3, c_shf3, cs3, g3, ave_shf, e, h

Sensible, latent, and soil heat fluxes can be recalculated using the 
values from probes 1, 2, 4, and 5, as follows.

ave_shf = (g1 + g2 + g4 + g5)/4

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

h = -(e + ave_shf +q)
