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) |

When the 30 minute data shows a home 30 signal of 35 or more, the bowen ratio, and sensible and latent heat flux measurements are incorrect Removing the jumper between 4L and AG on the CR10 and adding a jumper to Multiplexer 2, Set 6, between L1 and L2 fixed the problem.

Description: | ts4 went offscale and sm4 dropped to a constant 16% when a "new" program was installed on 3/30/05. The wrong program was installed. Because ts4 did not change with time, it did not mess up the calculation of e and h. e and h are slightly overestimated, but only by about 1%, far less than the system error. This is a rare type of instrument problem where the concequences are minimal. Therefore, e and h are not listed as incorrect in this DQR and are still usable during the stated period. |

DataStreams: | sgp30ebbrE20.b1 |
Description: | Effective 20050330.1900, the EBBR.E20 CR10 program was revised to improve the quality of the primary measurements as follows: 1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow. This is applied to the individual soil sets. Measurements outside the limits are rejected and the measurements within the limits are used to calculate the average soil heat flow. 2) Max and min limits are used to determine incorrect values of net radiation, sensible heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal. If AEM signal is outside the limits, h and e are set to 999s. If net radiation is outside the limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s. Virtually no incorrect soil measurement will affect the primary measurements of h and e. By setting h and e to 999s, it can be easily seen that the primary variables are incorrect; no other interpretation is possible. Prior to 20050330, the improved CR10 program was NOT in effect. DQRs have been submitted for known instances of incorrect soil measurements which affected the quality of the primary measurements of h and e. Note: the DQR begin date is the begin date of the sgp30ebbrE20.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE20.a1). |

DataStreams: | sgp30ebbrE20.b1 |
Description: | Beginning in FY2006, Data Quality Reports are not written for missing data or for situations when qc flags clearly show that the data is incorrect (this is true for most of the conditions listed below). DQRs are written for periods when data is incorrect, when the situation is not represented by qc flags in the data, and it's not obvious that the data should have been flagged as incorrect. The EBBR data is only useful for particular wind directions at each Extended Facility. Please use the following resources to help in interpreting the EBBR data. 1) qc flags in the EBBR data. 2) Instrument Mentor Monthly Summaries (IMMS) at http://www.db.arm.gov/IMMS/ 3) SGP EF Surface Conditions Observations (EFSCO) at http://198.124.96.210:591/sfc_cond1/default.htm 4) Surface fluxes are valid only for the following wind directions (in degrees): 0-230, 310-360 Note that there are wind directions at most sites for which the fetch is insufficient and therefore EBBR data is invalid. Appropriate fetch was determined from a 1/40 measurement height to fetch ratio, resulting in a required minimum fetch of 120 m. Particular attention should be paid to the limited valid wind directions for the Central Facility EBBR. The surface vegetation type for the EBBRs is grazed or ungrazed grassland (refer to the EFSCO for state). 5) Some conditions that commonly cause the EBBR primary measurements to be incorrect or missing follow: a) Sensible and latent heat fluxes are not accurate during times when the Automatic Exchange Mechanism (AEM) is not functioning properly. The AEM switches the gradient measuring instrumentation between the top and bottom positions every 15 minutes; this reduces the effects of instrument offsets. Sometimes the AEM does not reach it's full extent of travel, resulting in the home signal being zero. b) Sensible and latent heat fluxes are sometimes incorrect when surface soil heat flow is out of range, as seen in the average soil heat flux (ave_shf). c) Very light winds may be seen at nights for brief periods. Wind direction flops around a lot during low wind conditions (< 1.5 m/s) and is often unreliable during those periods. d) Missing data periods occur at times; this is usually a site data system collection/communication problem; it can also occur during replacement of the system with a newly calibrated unit. Missing data is sometimes filled in later from manual or automatic re-collection of the data. |
