Subject: | SGP/EBBR - EBBR E7 Soil Moisture Sensors #2 and #4 Negative |
DataStreams: | sgp15ebbrE7.a1, sgp30ebbrE7.a1 |
Description: | Soil moisture sensors #2 and #4 produced negative values for soil moisture frequently during the period, causing the quantities calculated from them to be incorrect. The version of the CR10X program at E7 does not have max/min limits on the outputs. The data needs to be examined to determine times of incorrect soil moisture values. The data values affected are shown below. 15 minute: r_sm1, r_sm2, r_sm3, r_sm4, r_sm5 30 minute: sm1, sm2, sm3, sm4, sm5, c_shf1, c_shf2, c_shf3, c_shf4, c_shf5, g1, g2, g3, g4, g5, ave_shf, e, h |

Subject: | SGP/EBBR - EBBR E22 Soil Moistures Negative |
DataStreams: | sgp15ebbrE22.a1, sgp30ebbrE22.a1 |
Description: | Because of the lack of rain, all soil moistures were negative during much of the period. The negative soil moistures caused soil heat storage and thus average soil heat flux to be smaller than they should have been. The sensible and latent heat fluxes were therefore reduced slightly (approximately 0-5%). The affected data are: 15 minute: r_sm1, r_sm2, r_sm3, r_sm4, r_sm5 30 minute: sm1, sm2, sm3, sm4, sm5, c_shf1, c_shf2, c_shf3, c_shf4, c_shf5, cs1, cs2, cs3, cs4, cs5, ces1, ces2, ces3, ces4, ces5, g1, g2, g3, g4, g5, ave_shf, e, h |

Subject: | SGP EBBR E19 - E19 EBBR Soil Heat Flow #1 Sign Reversed |
DataStreams: | sgp15ebbrE19.a1, sgp30ebbrE19.a1 |
Description: | The sign was reversed (heat flow plate #1 was installed upside down), causing incorrect measurements, as indicated. The average soil heat flow can be recalculated by using an average of soil sensor sets 2-5. The recalculated average soil heat flow can then be used to recalculate latent and sensible heat fluxes. |

DataStreams: | sgp15ebbrE13.a1, sgp30ebbrE13.a1 |
Description: | Soil Temperature #4 floated around, causing average soil heat flow to sometimes be too small (resulting too small a sensible heat flux and too large a latent heat flux) or too large (resulting in too large a sensible heat flux and too small a latent heat flux). Investigation of g4 will indicate when these conditions occurred and the likely effect on sensible and latent heat fluxes. |

The actual sensor heights are 18m for winds, 17m for temp, RH and vapor pressure, and 19m for barometric pressure which corresponds to 3.7m, 2.7m, and 4.7m above average canopy height respectively. |

Subject: | SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR |
DataStreams: | sgp30ebbrE2.a1, sgp30ebbrE18.a1, sgp30ebbrE19.a1, sgp30baebbrE2.c1, sgp30baebbrE18.c1, sgp30baebbrE19.c1 |
Description: | The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. (NOTE: The actual begin date of some of these data streams is as early as 5/22/97. This DQR applies to all 30m EBBR data.) |

Subject: | SGP/EBBR/E22 - Reprocess: E22 Soil Moisture Values Off End of Calibration at High Soil |
DataStreams: | sgp15ebbrE22.a1, sgp30ebbrE22.a1 |
Description: | Intermittently, since November 1997 soil moisture probes 1, 2, and 3 indicate small positive or else negative values when soil moisture is high (greater than 35%). This situation is similar to that at the Cement EBBR, although the soil at Cordell is not capable of holding as much water as that at Cement. The cause of the problem is inadequate range in the calibration curve equation. Very high soil moisture cannot be obtained with the calibration soil used by REBS. The soil moisture equations could be manipulated to allow larger soil moistures to be calculated. However, the infrequency of occurence does not justify doing so. The soil moisture data must be inspected by the data user to see when soil moisture values for one or more probes is inconsistent with the others. Recalculation of ave_shf, e, and h must be made using only the soil moisture sets with correct soil moisture values. Affected data values are (# for probe number): 15 minute: rr_sm# 30 minute: sm#, c_shf#, cs#, ces#, g#, ave_shf, e, h Sensible, latent, and soil heat fluxes can be recalculated using the soil probe sets that provide correct data. For example, if soil moisture 2 is incorrect, ave_shf = (g1 + g3 + g4 + g5)/4 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), If soil moistures 1 and 2 are incorrect, ave_shf = (g3 + g4 + g5)/3 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), If soil moistures 1, 2, and 3 are incorrect, ave_shf = (g4 + g5)/2 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), etc. |
