TL;DR: In this article, the authors evaluate the representativeness of flux footprints and evaluate potential biases as a consequence of the footprint-to-target-area mismatch, which can be used as a guide to identify site-periods suitable for specific applications.

TL;DR: In this paper, the authors derived a set of ecosystem functions from a dataset of surface gas exchange measurements across major terrestrial biomes and climate zones and found that most of the variability within ecosystem functions (71.8%) is captured by three key axes.

Understory CO2, sensible heat, and latent heat fluxes in a black spruce forest in interior Alaska
Hiroki Ikawa,Taro Nakai,Taro Nakai,Robert Busey,Yongwon Kim,Hideki Kobayashi,Shin Nagai,Masahito Ueyama,Kazuyuki Saito,Hirohiko Nagano,Rikie Suzuki,Larry D. Hinzman +11 more
TL;DR: In this article, the authors measured CO2, sensible heat, and latent heat fluxes with eddy covariance (EC) in one of those large canopy gaps, and estimated understory fluxes in a black spruce forest in 2011-2014.
