DataStreams: | sgp30ebbrE25.b1 |
Description: | The #1 soil heat flow sensor developed a +60 W m-2 bias and thus indicated higher soil heat flows than the other sensors. This results in slightly higher sensible and latent heat fluxes than is correct. The sensor was replaced on 2/21/01. |

DataStreams: | sgp30ebbrE25.b1 |
Description: | Soil heat flow 5 was either too large negative or negative when it should have been positive; the cause of the negative offset is unknown, but is often the result of a failed J-panel over-voltage protection device. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) |

Subject: | SGP/EBBR/E25 - Bowen Ratio Usually Negative - Fluxes Incorrect |
DataStreams: | sgp30ebbrE25.b1 |
Description: | Submitted By: _x_ Instrument Mentor ___ EST Member ___ Science Team Member ___ Other Platform/Measurement: EBBR/Bowen ratio, sensible and latent heat fluxes What level data: (raw,a0,a1,b1,c1 etc): a1 (15 and 30 minute) What location was the data collected at: E25, Seminole, OK Period of time in question (Times vary for different days) Begin Date 10/22/97 and on Discussion of Problem: Bowen ratio is normally negative, as if it is somehow being biased. Latent and sensible heat fluxes are apparently incorrect much of the time, especially during the daytime. All supporting measurements seem to be incorrect; therefore the error must be occurring in the measured T and RH gradients. This situation has occured since the EBBR unit was installed on 22 October 1997. A work request has been submitted for a full six month check to be performed on the system. Hopefully the checks will point to the source of the problem. The right relative humidity was biased. The right T/RH probe was replaced on 4/22/98 at 1700 GMT, but it had a more defective RH sensor in it, causing right RH to sit at 112-114 percent. This probe was itself replaced on 5/6/98 at 1645 GMT, thereby taking care of the negative Bowen ratio problem. |

Description: | On 24 April 1998 the humidity reported by the right T/RH probe soared to 112% to 114% and remained there until replacement of the probe on 6 May 1998. Sensible and latent heat fluxes and some humidity and vapor pressure data for the period are incorrect. The data fields that are incorrect are: 5 minute: hum_top, hum_bot, vp_top, vp_bot 15 minute: mv_hum_r 30 minute: hum_top, hum_bot, vp_top, vp_bot, bowen, e, h |

Subject: | SGP/EBBR/E25 - Six-Month Checks |
DataStreams: | sgp30ebbrE25.b1 |
Description: | During EBBR 6-month checks (formally called 3 month checks) the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during these periods do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate correct gradients. Checks performed just before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period indicated. |

Description: | On 15 July 1998 the EBBR AEM was moved to a higher position. The complexity of the task required that the AEM be disabled for what amounted to two half hour average periods, during which the temperatures, relative humidities, vapor pressures, Bowen ratio, and latent and sensible heat fluxes were all incorrect. |
