DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1 |
Description: | Soil temperature #2 was intermittently incorrect. The cause is not yet known. The indicated other measurements were also incorrect because soil temperature #2 was used in the calculations of the quantities. Soil moisture (30 minute only) was affected because version 6 of the EBBR datalogger program used a multiplication of soil temperature and soil moisture as part of the adjustment of soil moisture for soil temperature. This was discovered to be a poor technique soon after it was implemented, but E2 will continue to use version 6 until a replacement EBBR unit is available. Changeout dates of the EBBR units can be found on the EBBR Instrument web page. |

Subject: | SGP/EBBR/E2 - Improved EBBR CR10 Program |
DataStreams: | sgp30ebbrE2.b1 |
Description: | Effective 20050324.1700, the EBBR.E2 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 20050324, 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 sgp30ebbrE2.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE2.a1). |
