Discussion of Problem:
A lightning "strike" to the EF 8 Facility shortly after 0900 GMT on
14 July 1997 caused the failure of several EBBR sensors, the solar panel
voltage regulator, and the CR10 datalogger. A previous DQR indicated this.
During the period listed above, all but one of the damaged parts were
replaced. Replacements occurred on 22 July, 5 August, 19 August, and
16 September. Some sensors began producing correct data immediately after
their replacement; however the temperature measurements were incorrect
until 15 October, when the reference temperature probe, with which they are
corrected, was reconnected. Only the soil heat flow probe #2 remains to be
replaced. Average soil, sensible, and latent heat fluxes are therefore
now ,still, incorrect, but can be recomputed using only four sets of soil
heat flow probes, as below.
ave_shf = (g1 +g3 + g4 + g5)/4
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q) |
