Quantifying global terrestrial photosynthesis is essential to understanding the global carbon
cycle and the climate system. Remote sensing has played a pivotal role in advancing our …

In this review, I first address the basics of gas exchange, water‐use efficiency and carbon
isotope discrimination in C3 plant canopies. I then present a case study of water‐use …

Plant functional traits determine vegetation responses to environmental variation, but
variation in trait values is large, even within a single site. Likewise, uncertainty in how these …

Satellite‐derived sun‐induced chlorophyll fluorescence (SIF) has been increasingly used for
estimating gross primary production (GPP). However, the relationship between SIF and GPP …

Amazonian evergreen forests show distinct canopy phenology and photosynthetic
seasonality but the climatic triggers are not well understood. This imposes a challenge for …

Satellite and tower-based metrics of forest-scale photosynthesis generally increase with dry
season progression across central Amazônia, but the underlying mechanisms lack …

Theoretical and eddy covariance studies demonstrate that aerosol‐loading stimulates
canopy photosynthesis, but field evidence for the aerosol effect on tree growth is limited …

Aerosols can affect crop photosynthesis by altering radiation and meteorological conditions.
By combining field observations, mechanistic modeling, and satellite‐retrieved solar …

Terrestrial gross primary productivity (GPP) is the largest component of the global carbon
cycle and a key process for understanding land ecosystems dynamics. In this study, we used …

Tropical forests are a key determinant of the functioning of the Earth system, but remain a
major source of uncertainty in carbon cycle models and climate change projections. In this …
