Subject:	SGP/EBBR/E27 - Water in Net Radiometer; Surface Fluxes are Incorrect
DataStreams:	sgp15ebbrE27.a1, sgp15ebbrE27.b1, sgp30ebbrE27.a1, sgp30ebbrE27.b1, sgp5ebbrE27.a1
Description:	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.

Subject:	SGP/EBBR/E27 - Missing data during system update
DataStreams:	sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:	Some soil parameters were slightly incorrect since EBBR.E27 was installed in May 2003. While the coefficients were being updated, data collection was suspended resulting in missing data for the specified period. No significant effects (1% or less) on the surface heat flux data would have occurred from using the slightly incorrect coefficients. Therefore, flagging of the surface flux data from the time of installation of E27 is unwarranted.
