Trends in North American net primary productivity derived from satellite observations, 1982-1998

Trends in North American net primary productivity derived from satellite observations, 1982-1998

Global Biogeochemical Cycles 16(2): 2/1-2/15

Net primary productivity (NPP) in North America was computed for the years 1982-1998 using the Carnegie-Ames-Stanford approach (CASA) carbon cycle model. CASA was driven by a new, corrected satellite record of the normalized difference vegetation index at 8-km spatial resolution. Regional trends in the 17-year NPP record varied substantially across the continent. Croplands and grasslands of the Central Plains and eastern Canadian forests experienced summer increases in NPP.
