Intercomparison, interpretation, and assessment of spring phenology in North America estimated from remote sensing for 1982-2006
Michael A. White,Kirsten M. de Beurs,Kamel Didan,David W. Inouye,Andrew D. Richardson,Olaf P. Jensen,John O'Keefe,G. Zhang,Ramakrishna R. Nemani,Willem J. D. van Leeuwen,Jesslyn F. Brown,Allard de Wit,Michael E. Schaepman,Xioamao Lin,Michael D. Dettinger,Amey S. Bailey,John S. Kimball,Mark D. Schwartz,Dennis D. Baldocchi,J. T. Lee,William K. Lauenroth +20 more
TL;DR: In this paper, the authors assess 10 start-of-spring (SOS) methods for North America between 1982 and 2006 and find that SOS estimates were more related to the first leaf and first flowers expanding phenological stages.
Journal ArticleDOI
Analysis of monotonic greening and browning trends from global NDVI time-series
Rogier de Jong,Sytze de Bruin,Allard de Wit,Michael E. Schaepman,Michael E. Schaepman,David Dent +5 more
TL;DR: In this article, the authors applied harmonic analysis and non-parametric trend tests to the GIMMS NDVI dataset (1981-2006) to detect greening and browning trends; especially the global coverage of time-series normalized difference vegetation index (NDVI) data which are available from 1981.
Journal ArticleDOI

TL;DR: In this paper, the authors evaluate the simulation results of 14 global gridded crop modeling groups that have contributed historic crop yield simulations for maize, wheat, rice and soybean to the Global Gridded Crop Model Intercomparison (GGCMI) of the AgMIP.
Journal ArticleDOI
Strong contribution of autumn phenology to changes in satellite-derived growing season length estimates across Europe (1982–2011)
Irene Garonna,Rogier de Jong,Allard de Wit,Caspar A. Mücher,Bernhard Schmid,Michael E. Schaepman +5 more
TL;DR: An evaluation of Pan-European LSP and its changes over the past 30 years is presented, using the longest continuous record of Normalized Difference Vegetation Index (NDVI) available to date in combination with a landscape-based aggregation scheme to test for temporal trends in activity of terrestrial vegetation.
Journal ArticleDOI
25 years of the WOFOST cropping systems model
Allard de Wit,Hendrik Boogaard,Davide Fumagalli,Sander Janssen,Rob Knapen,Daniel van Kraalingen,Iwan Supit,Raymond van der Wijngaart,Kees van Diepen +8 more
TL;DR: This paper provides an updated description of the WOFOST model and reflects on the lessons learned over the last 25 years, including issues like system performance, model sensitivity, spatial model setup, parameterization and calibration approaches as well as software implementation and version management.
