Subject: | SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect |
DataStreams: | sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1 |
Description: | Soil Temperature #2 was intermittently incorrect. The cause is unknown. The indicated measurements that are calculated using soil temperature are also incorrect. Soil moisture #2 (30 minute only) was also affected because version 6 of the EBBR datalogger program uses 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. When soil temperature #2 is large negative, soil moisture #2 is often twice as large as it should be. EBBR unit changeout dates are listed on the EBBR instrument web page. |
