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.

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.

  • Corrected sensible heat flux(h)
  • friction velocity(ustar)
  • CO2 flux(fc)
  • Latent heat flux(lv_e)
