Drought effect on vegetation Gross Primary Production (GPP) is usually modeled as a function of Vapor Pressure Deficit (VPD) and\/or soil moisture. Climate projections suggest a strong likelihood of increasing trend in VPD, while regional changes in precipitation are less certain. This difference in projections between VPD and precipitation can cause considerable discrepancies in the predictions of vegetation behavior depending on how ecosystem models represent the drought effect. In this study, we scrutinized the model responses to drought using the 30-year record of Global Inventory Modeling and Mapping Studies (GIMMS) 3g Normalized Difference Vegetation Index (NDVI) dataset. A diagnostic ecosystem model, Terrestrial Observation and Prediction System (TOPS), was used to estimate global GPP from 1982 to 2009 under nine different experimental simulations. The control run of global GPP increased until 2000, but stayed constant after 2000. Among the simulations with single climate constraint (temperature, VPD, rainfall and solar radiation), only the VPD-driven simulation showed a decrease in 2000s, while the other scenarios simulated an increase in GPP. The diverging responses in 2000s can be attributed to the difference in the representation of the impact of water stress on vegetation in models, i.e., using VPD and\/or precipitation. Spatial map of trend in simulated GPP using GIMMS 3g data is consistent with the GPP driven by soil moisture than the GPP driven by VPD, confirming the need for a soil moisture constraint in modeling global GPP.<\/jats:p>","DOI":"10.3390\/rs5031258","type":"journal-article","created":{"date-parts":[[2013,3,13]],"date-time":"2013-03-13T04:22:17Z","timestamp":1363148537000},"page":"1258-1273","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Structural Uncertainty in Model-Simulated Trends of Global Gross Primary Production"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7706-1854","authenticated-orcid":false,"given":"Hirofumi","family":"Hashimoto","sequence":"first","affiliation":[{"name":"Division of Science and Environmental Policy, California State University\u2013Monterey Bay, Seaside, CA 93955, USA"},{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weile","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Science and Environmental Policy, California State University\u2013Monterey Bay, Seaside, CA 93955, USA"},{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Milesi","sequence":"additional","affiliation":[{"name":"Division of Science and Environmental Policy, California State University\u2013Monterey Bay, Seaside, CA 93955, USA"},{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Xiong","sequence":"additional","affiliation":[{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangram","family":"Ganguly","sequence":"additional","affiliation":[{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"},{"name":"Bay Area Environmental Research Institute, Sonoma, CA 95476, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zaichun","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Earth and Environment, Boston University, Boston, MA 02215, USA"},{"name":"College of Resources Science & Technology, State Key Laboratory of Earth Processes and Resource Ecology, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramakrishna","family":"Nemani","sequence":"additional","affiliation":[{"name":"NASA Ames Research Center, Moffett Field, CA 94035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,3,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"834","DOI":"10.1126\/science.1184984","article-title":"Terrestrial gross carbon dioxide uptake: Global distribution and covariation with climate","volume":"329","author":"Beer","year":"2010","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3161","DOI":"10.1111\/j.1365-2486.2011.02450.x","article-title":"A historical meta-analysis of global terrestrial net primary productivity: Are estimates converging?","volume":"17","author":"Ito","year":"2011","journal-title":"Glob.
