TABLE 6-11. Data Fields in the Flux_CSFormat Data Output Table
Data Field Name Units Description Data Field Included
FETCH_MAX m
Distance upwind where the maximum
contribution to the footprint is found
Always
FETCH_90 m
Upwind distance that contains 90% of
cumulative footprint
Always
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.
Always
UPWND_DIST_INTRST m
Upwind distance of interest for the
average wind direction
Always
FTPRNT_DIST_INTRST %
Percentage of footprint from within
the upwind range of interest
Always
FTPRNT_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.
