Upscaling Net Ecosystem Exchange Over Heterogeneous Landscapes With Machine Learning [PDF]
Journal of Geophysical Research: Biogeosciences, 2021 This paper discusses different feature selection methods and CO2 flux data sets with a varying quality‐quantity balance for the application of a Random Forest model to predict daily CO2 fluxes at 250 m spatial resolution for the Rur catchment area in ...

Mapping the net ecosystem exchange of CO2 of global terrestrial systems
International Journal of Applied Earth Observations and Geoinformation, 2023 Net ecosystem exchange of CO2 (NEE) is a useful tool to analyze the carbon balance of different areas. Since it is impossible to measure NEE in-situ at a regional or global scale, this study has conducted a NEE estimation model to map the NEE of global ...

Differential responses of net ecosystem exchange of carbon dioxide to light and temperature between spring and neap tides in subtropical mangrove forests. [PDF]
ScientificWorldJournal, 2014 The eddy flux data with field records of tidal water inundation depths of the year 2010 from two mangroves forests in southern China were analyzed to investigate the tidal effect on mangrove carbon cycle.

Pan-Arctic modelling of net ecosystem exchange of CO2. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2013 Net ecosystem exchange (NEE) of C varies greatly among Arctic ecosystems. Here, we show that approximately 75 per cent of this variation can be accounted for in a single regression model that predicts NEE as a function of leaf area index (LAI), air temperature and photosynthetically active radiation (PAR).

Carbon dioxide net assimilation exchange in a young pecan nut orchard during the growth cycle [PDF]
Global Journal of Environmental Science and Management, 2023 BACKGROUND AND OBJECTIVES: Pecan nut trees (Carya illinoensis K), due to their condition as woody and long-living species, in addition to the contribution of nuts for consumption, may also have an essential role in assimilating carbon dioxide and ...

Estimating the Net Ecosystem Exchange at Global FLUXNET Sites Using a Random Forest Model
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Despite considerable progress in scaling carbon fluxes from eddy covariance sites to globe, significant uncertainties still exist when estimating the global net ecosystem exchange (NEE).
