Summary

Gross primary productivity (GPP) is a measure of ecosystem functioning. It represents the cumulative effect of ecological processes such as soil formation, nutrient cycling, photosynthesis, and population dynamics. Productivity may be related to patterns in species diversity (Currie 1991, Hector et al. 1999). For example, the most common hypothesis is that species diversity is greatest at moderate levels of primary productivity (Loreau et al. 2001). GPP quantifies the amount of carbon absorbed by living plants during photosynthesis. GPP units are in kilograms of carbon per square metre per year (kg C/m 2/yr). The GPP dataset was developed from MODIS GPP/NPP (MOD17) 1-km 2 resolution satellite imagery (Zhao et al. 2005, 2006, Zhao [...]

Canadian BEACONs Project, University of Alberta. The GPP dataset was developed from MODIS GPP/NPP (MOD17) 1-km2 resolution satellite imagery (Zhao et al. 2005, 2006, Zhao and Running 2010; Figure B2). MODIS GPP has an 8-day temporal resolution and is ideal for monitoring spatial patterns in photosynthetic activity (Heinsch et al. 2003). The current GPP data represents the mean of 14 years of data, measured from 2000 to 2014.
