SGP/EBBR/E7 - Soil Heat Flow #5 Incorrect

Soil Heat Flow Plate #5 data was intermittently incorrect at first 
(values too small negative), then was almost constantly so during the 
last half of the period.

Comparison of the individual soil heat flows will quickly show the times
that soil heat flow #5 was incorrect.

SGP/EBBR/E7  - AEM Malfunction, Some Data Incorrect

After a while, the teflon slides on the AEMs warp from
heat and use.  This tends to make the AEM drag, jam, and get hung.
This happened at E7 EBBR.

Replacement of the AEM resolved the problem.

SGP/EBBR/E7 - Water in Net Radiometer Domes; Surface Fluxes are Incorrect

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.
