Description: | The AEM kept stopping in one of three positions, none of which allow sensible heat flux, latent heat flux, or Bown ratio to be calculated correctly. These and the gradient measurements are incorrect for the period indicated. The AEM stopped in either the home15 position (home signal about 53), the home 30 position (home signal about 23), or inbetween these two (home signal 1 to 2). |

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. |

Description: | The upper dome of the net radiometer was broken. Normally this alone does not affect the net radiation measurement. However, in this case the breakage must have been more than just a bird claw hole or a crack, resulting in obstruction of the top sensing surface of the net radiometer and greatly reduced net radiation measurements. Sensible and latent heat fluxes were reduced as a result. |
