Subject: | SGP/EBBR/E4 - Reprocess: Intermittently bad soil heat flux sensor #4 |
DataStreams: | sgp30ebbrE4.b1, sgp15ebbrE4.b1 |
Description: | On October 23, 1993 soil heat flux sensor #4 (which had been installed on September 23, 1993) of the Plevna, KS EBBR (E4) developed an intermittent poor electrical contact with the multiplexer. Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e, and corrupted 15 minute values of mv_hft4 resulted from this situation. 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) |
Suggestions: | Recalculate sensible, latent and soil heat fluxes using the equations provided. |
