Effect of climate dataset selection on simulations of terrestrial GPP: Highest uncertainty for tropical regions.

PLoS ONE, 2018
Biogeochemical models use meteorological forcing data derived with different approaches (e.g. based on interpolation or reanalysis of observation data or a hybrid hereof) to simulate ecosystem processes such as gross primary productivity (GPP).

Can Gross Primary Productivity Products be effectively evaluated in regions with few observation data?

GIScience & Remote Sensing, 2023
The dynamics of Gross Primary Productivity (GPP) is key to understand the global carbon cycle. Multiple GPP products are currently available based on remote sensing, Light Use Efficiency model (LUE) or diagnostic biophysical model.

Knowledge mining for the differentiation pattern with respect to the productivity and trophic status of some selected lakes of Western Himalayas

Frontiers in Environmental Science, 2023
The present study deals with an account of the primary productivity and trophic status of Rewalsar, Kuntbhyog, and Prashar lakes of Western Himalayas. Seasonal variations in gross primary productivity (GPP) (g C m–2 day–1), net primary productivity (NPP,

Immediate and carry‐over effects of late‐spring frost and growing season drought on forest gross primary productivity capacity in the Northern Hemisphere

Global Change Biology, 2023
Forests are increasingly exposed to extreme global warming‐induced climatic events. However, the immediate and carry‐over effects of extreme events on forests are still poorly understood.

A new approach for estimating northern peatland gross primary productivity using a satellite-sensor-derived chlorophyll index

, 2011
Carbon flux models that are largely driven by remotely sensed data can be used to estimate gross primary productivity (GPP) over large areas, but despite the importance of peatland ecosystems in the global carbon cycle, relatively little attention has ...

The 2010 spring drought reduced primary productivity in southwestern China

Environmental Research Letters, 2012
Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention.

The direct and indirect effects of the environmental factors on global terrestrial gross primary productivity over the past four decades

Environmental Research Letters, 2023
Gross primary productivity (GPP) is jointly controlled by the structural and physiological properties of the vegetation canopy and the changing environment.

Changes in Gross Primary Production (GPP) over the Past Two Decades Due to Land Use Conversion in a Tourism City [PDF]

ISPRS International Journal of Geo-Information, 2018
Understanding the changes in gross primary production (GPP), which is the total carbon fixation by terrestrial ecosystems through vegetation photosynthesis, due to land use conversion in a tourism city is important for carbon cycle studies. Satellite data from Landsat 5, Landsat 7 and Landsat 8 and meteorological data are used to calculate annual GPP ...

Generation of High Resolution Vegetation Productivity from a Downscaling Method

Remote Sensing, 2018
Accurately estimating vegetation productivity is important in the research of terrestrial ecosystems, carbon cycles and climate change. Although several gross primary production (GPP) and net primary production (NPP) products have been generated and many
