Environmental controls on the light use efficiency of terrestrial gross primary production. [PDF]

Glob Chang Biol, 2022
Gross primary production (GPP) by terrestrial ecosystems is a key quantity in the global carbon cycle. The instantaneous controls of leaf-level photosynthesis are well established, but there is still no consensus on the mechanisms by which canopy-level ...

Diagnostic assessment of European gross primary production [PDF]

Global Change Biology, 2008
AbstractWe present an approach to estimate gross primary production (GPP) using a remotely sensed biophysical vegetation product (fraction of absorbed photosynthetically active radiation, FAPAR) from the European Commission Joint Research Centre (JRC) in conjunction with GPP estimates from eddy covariance measurement towers in Europe.

Constraining uncertainty in projected gross primary production with machine learning [PDF]

Journal of Geophysical Research: Biogeosciences, 2020
<p>By absorbing about one quarter of the total anthropogenic CO<sub>2</sub> emissions, the terrestrial biosphere is an important carbon sink of Earth’s carbon cycle. A key metric of this process is the terrestrial gross primary production (GPP), which describes the biogeochemical ...

Uncertainty analysis of gross primary production partitioned from net ecosystem exchange measurements [PDF]

Biogeosciences, 2016
Gross primary production (GPP) can be separated from flux tower measurements of net ecosystem exchange (NEE) of CO2. This is used increasingly to validate process-based simulators and remote-sensing-derived estimates of simulated GPP at various time ...

Accelerated dryland expansion regulates future variability in dryland gross primary production [PDF]

Nature Communications, 2020
Earth’s drylands are expected to expand due to climate change, but how this will affect vegetation remains unclear. Here the authors use models to show that despite expansion, primary productivity in drylands is likely to increase through the 21st ...

Sea surface temperature influence on terrestrial gross primary production along the southern California Current [PDF]

PLoS One, 2015
Some land and ocean processes are related through connections (and synoptic-scale teleconnections) to the atmosphere. Synoptic-scale atmospheric (El Niño/Southern Oscillation [ENSO], Pacific Decadal Oscillation [PDO], and North Atlantic Oscillation [NAO])

Effects of spatial–temporal land cover distribution on gross primary production and net primary production in Schleswig-Holstein, northern Germany [PDF]

Carbon Balance and Management, 2020
Background Annual total Gross Primary Production (GPP) and Net Primary Production (NPP) and the annual total stored GPP and NPP are tightly coupled to land cover distributions because the distinct vegetation conditions of different land cover classes ...

A global hourly gross primary production dataset from 2001 to 2020 [PDF]

Scientific Data
Fine-resolution estimation of gross primary production (GPP) is essential for advancing our knowledge of ecosystem carbon cycling. However, most existing global GPP products are constrained by coarse temporal resolutions (typically ≥ 8 days), limiting ...

A 30-m gross primary production dataset from 2016 to 2020 in China [PDF]

Scientific Data
Estimating gross primary production (GPP) of terrestrial ecosystems is important for understanding the terrestrial carbon cycle. However, existed nationwide GPP datasets are primarily driven by coarse spatial resolutions (≥500 m) remotely sensed data ...
