Description: | On September 1, 1993 the EBBR system at Plevna, E4, was relocated in the
same field. However, soil contact for soil heat flux plate #5 was not
properly established. This resulted in somewhat high positive and very
high negative outputs, depending on the direction of soil heat flow.
Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e,
and corrupted 15 minute values of mv_hft4 resulted.
The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and
are not recoverable. The other quantities can be recalculated using
the four functioning sets of soil sensors. (Note: Soil heat flux
sensor #4 was also malfunctioning during part of the time period
identified. That problem is identified in two separate DQRs. See
D931108.5 and D020701.2 for the equations to use while sensor #4
was not working properly)
ave_shf = (g1 + g2 + g3 + g4)/4
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q) |
