Journal ArticleDOI
A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part II: The Generation of Global Fields of Terrestrial Biophysical Parameters from Satellite Data
Piers J. Sellers,Compton J. Tucker,G. James Collatz,Sietse O. Los,Christopher O. Justice,D. A. Dazlich,David A. Randall +6 more
TL;DR: In this article, the authors used satellite data to specify the time-varying phonological properties of FPAR, leaf area index, and canopy greenness fraction, and applied corrections to the source NDVI dataset to account for anomalies in the data time series, the effect of variations in solar zenith angle, data dropouts in cold regions where a temperature threshold procedure designed to screen for clouds also eliminated cold land surface points, and persistent cloud cover in the Tropics.
Journal ArticleDOI
Higher northern latitude normalized difference vegetation index and growing season trends from 1982 to 1999
Compton J. Tucker,Daniel Slayback,Jorge E. Pinzon,Sietse O. Los,Ranga B. Myneni,Malinda G. Taylor +5 more
TL;DR: The authors' results support surface temperature increases within the same period at higher northern latitudes where temperature limits plant growth.
Journal ArticleDOI
Biospheric Primary Production During an ENSO Transition
Michael J. Behrenfeld,James T. Randerson,Charles R. McClain,Gene C. Feldman,Sietse O. Los,Compton J. Tucker,Paul G. Falkowski,Christopher B. Field,Robert Frouin,Wayne E. Esaias,Dorota D. Kolber,Nathan H. Pollack +11 more
TL;DR: Increases in ocean NPP were pronounced in tropical regions where El Niño–Southern Oscillation impacts on upwelling and nutrient availability were greatest, and Globally, land NPP did not exhibit a clear ENSO response, although regional changes were substantial.

Journal ArticleDOI
Comparison of radiative and physiological effects of doubled atmospheric CO2 on climate
Piers J. Sellers,Lahouari Bounoua,G. J. Collatz,David A. Randall,D. A. Dazlich,Sietse O. Los,Joseph A. Berry,I. Fung,Compton J. Tucker,Christopher B. Field,Tommy G. Jensen +10 more
TL;DR: In this article, the physiological response of terrestrial vegetation when directly exposed to an increase in atmospheric carbon dioxide (CO 2 ) concentration could result in warming over the continents in addition to that due to the conventional CO 2 “greenhouse effect.
