Subject:	HFE/ECOR/M1 - Sonic failure
DataStreams:	hfe30ecorM1.b1
Description:	The sonic datastream were "garbled", possibly associated with a serial line damage to the LI-7500 serial port or the Versalogic SBC serial port. Garbled data condition existed through 10/09/08 0030 GMT followed by missing data through 10/12/08 0230 GMT.

Subject:	HFE/ECOR/M1 - Flux Data Incorrect For Some Wind Directions
DataStreams:	hfe30ecorM1.b1
Description:	For some wind directions the horizontal fetch was not representative of the fields surrounding the AMF. Therefore, for the wind direction range 191-349 degrees, the fluxes are affected by insufficient fetch, and surfaces, buildings, and vegetation that are not similar to the local field conditions.
Measurements:	hfe30ecorM1.b1: Corrected sensible heat flux(h) friction velocity(ustar) CO2 flux(fc) Latent heat flux(lv_e)
