8.
Data quality qualifications based on steady state conditions, surface-
layer turbulence characteristics, and wind directions following Foken
et al. 2012 (or Foken et al. 2004 for the Flux_AmeriFluxFormat
output table).
9.
If energy balance sensors are used, calculation of energy closure based
on energy balance measurements and corrected sensible and latent
heat fluxes.
10.
Footprint characteristics are computed using Kljun et al (2004) and
Kormann and Meixner (2001).
