1560 R EPORTS Climate-Driven Increases in Global Terrestrial Net Primary (2008)
Ramakrishna R. Nemani, Charles D. Keeling, Hirofumi Hashimoto, William M. Jolly, Stephen C. Piper, Compton J. Tucker, ...
Recent climatic changes have enhanced plant growth in northern mid-latitudes and high latitudes. However, a comprehensive analysis of the impact of global climatic changes on vegetation productivity...
El Niño–Southern Oscillation–induced variability in terrestrial carbon cycling (2008)
Hirofumi Hashimoto, Ramakrishna R. Nemani, Michael A. White, William M. Jolly
[1] We examined the response of terrestrial carbon fluxes to climate variability induced by the El Niño–Southern Oscillation (ENSO). We estimated global net primary production (NPP) from 1982 to...
A Continuous Satellite-Derived Measure of Global Terrestrial Primary Production (2004)
STEVEN W. RUNNING, RAMAKRISHNA R. NEMANI, FAITH ANN HEINSCH, MAOSHENG ZHAO, MATT REEVES, HIROFUMI HASHIMOTO
Until recently, continuous monitoring of global vegetation productivity has not been possible because of technological limitations. This article introduces a new satellite-driven monitor of the...
