A new proliferation of optical instruments that can be attached to towers over or within
ecosystems, or 'proximal'remote sensing, enables a comprehensive characterization of …

Abstract Purpose of Review Terrestrial ecosystems in the Arctic-Boreal region play a crucial
role in the global carbon cycle as a carbon sink. However, rapid warming in this region …

The seasonal timing and magnitude of photosynthesis in evergreen needleleaf forests
(ENFs) has major implications for the carbon cycle and is increasingly sensitive to changing …

The boreal forest is shifting, driven by warming temperatures, altered precipitation patterns,
and intensifying disturbances (1–3). Shifts in tree cover dynamics can be key indicators of …

Robust carbon monitoring systems are needed for land managers to assess and mitigate the
changing effects of ecosystem stress on western United States forests, where most …

Solar‐induced fluorescence (SIF) is a proxy of ecosystem photosynthesis that often scales
linearly with gross primary productivity (GPP) at the canopy scale. However, the mechanistic …

The timing and progression of the spring thaw transition in high northern latitudes (HNL)
coincides with warmer temperatures and landscape thawing, promoting increased soil …

To reduce its greenhouse gas (GHG) impact, the United States government plans GHG
Measurement, Monitoring, and Information System (MMIS) activities to better quantify GHG …

The ability to optically detect reflected and emitted photons from vegetation has transformed
our understanding of forest ecophysiology, enabling detailed assessments of …

There has been widespread interest in develo** trait-based models to predict
photosynthetic capacity from leaves to ecosystems (Walker et al., 2014; Xu & Trugman …
