DataStreams: | sgp30ebbrE9.a1, sgp30ebbrE9.b1, sgp5ebbrE9.a1 |
Description: | The Right Humidity measurement was normally incorrect, although it is often difficult to determine it by looking at the measurement. The measurements float around, sometimes being too large and sometimes being too small, through most of the day, particularly for the hour before sunset through the hour after sunrise. Great care and comparison with surrounding EBBR sites would be needed to be able to use any of the latent and sensible heat flux measurements from E9 for this period. Another DQPR has been issued to fix this problem, which has eluded repair efforts so far. |

Subject: | SGP/EBBR/E9 - Improved EBBR CR10 Program |
DataStreams: | sgp30ebbrE9.b1 |
Description: | Effective 20050322.1600, the EBBR.E9 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 20050322, 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 sgp30ebbrE9.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE9.a1). |
