TABLE C-21. Data Fields in the Flux_CSFormat Data Output Table
Data Field Name Units Description
Data Field
Included
FETCH_55 m
Upwind distance that contains 55%
of footprint
Always
FETCH_40 m
Upwind distance that contains 40%
of footprint. If NAN is returned,
integration of the model never
reached 90% within the allowable
distance of integration. See the
Footprint appendix in the EasyFlux
DL CR6OP
manual for more details.
Always
UPWND_DIST_INTRST m
Upwind distance of interest for the
average wind direction
Always
FP_DIST_INTRST %
Percentage of footprint from within
the upwind range of interest
Always
FP_EQUATION text
Returns either
Kljun
or
KormannMeixner ; the model of
Kljun et al. (2004) is used for
applicable atmospheric conditions,
else the model of Kormann &
Meixner (2001) is used
