A new global oceanic multi-model net primary productivity data product [PDF]
Earth System Science Data, 2023 Net primary production of the oceans contributes approximately half of the total global net primary production, and long-term observational records are required to assess any climate-driven changes. The Ocean Colour Climate Change Initiative (OC-CCI) has

Degradation of net primary production in a semi-arid rangeland [PDF]
Biogeosciences, 2016 Abstract. Anthropogenic land degradation affects many biogeophysical processes including reductions of net primary production (NPP). Degradation occurs at scales from small fields to continental and global. While measurement and monitoring of NPP in small areas is routine in some studies, for scales larger than 1 km2, and certainly global, there is no ...

Net primary production of forests: a constant fraction of gross primary production? [PDF]
Tree Physiology, 1998 Considerable progress has been made in our ability to model and measure annual gross primary production (GPP) by terrestrial vegetation. But challenges remain in estimating maintenance respiration (R(m)) and net primary production (NPP). To search for possible common relationships, we assembled annual carbon budgets from six evergreen and one deciduous

Ozone and haze pollution weakens net primary productivity in China [PDF]
Atmospheric Chemistry and Physics, 2017 Atmospheric pollutants have both beneficial and detrimental effects on carbon uptake by land ecosystems. Surface ozone (O3) damages leaf photosynthesis by oxidizing plant cells, while aerosols promote carbon uptake by increasing diffuse radiation and ...

Crop Yield Estimation in the Canadian Prairies Using Terra/MODIS-Derived Crop Metrics
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 We evaluated the utility of Terra/MODIS-derived crop metrics for yield estimation across the Canadian Prairies. This study was undertaken at the Census Agriculture Region (CAR) and the Rural Municipality (RM) of the province of Saskatchewan, in three ...
