Description: | On September 11, 1993 soil heat flux sensor #4 of the Plevna, KS EBBR
(E4) malfunctioned. The sensor was replaced September 23, 1993 before
1600. Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e,
and corrupted 15 minute values of mv_hft4 resulted from the sensor
malfunction.
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 three
functioning sets of soil sensors. (Note: Soil heat flux sensor #5 was also
malfunctioning during the time periods identified and has therefore been
eliminated from the recalculation equations. This problem is identified
in a separate DQR.)
ave_shf = (g1 + g2 + g3)/3
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q) |
