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.
Measurements:hfe30ecorM1.b1:
  • Corrected sensible heat flux(h)
  • friction velocity(ustar)
  • CO2 flux(fc)
  • Latent heat flux(lv_e)

HFE/AOS/M1 - Data processing problem
DataStreams:hfeaosM1.a1, hfenoaaaosM1.b1, hfenoaaaosavgM1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.
