However, it is still challenging to model crop yields based on remotely sensed data due to the variation in radiation use efficiency (RUE) across crop types and the effects of spatial heterogeneity. In this paper, we propose a production efficiency model-based method to estimate corn and soybean yields with MODerate Resolution Imaging Spectroradiometer (MODIS) data by explicitly handling the following two issues: (1) field-measured RUE values for corn and soybean are applied to relatively pure pixels instead of the biome-wide RUE value prescribed in the MODIS vegetation productivity product (MOD17); and (2) contributions to productivity from vegetation other than crops in mixed pixels are deducted at the level of MODIS resolution. Our estimated yields statistically correlate with the national survey data for rainfed counties in the Midwestern US with low errors for both corn (R2 = 0.77; RMSE = 0.89 MT\/ha) and soybeans (R2 = 0.66; RMSE = 0.38 MT\/ha). Because the proposed algorithm does not require any retrospective analysis that constructs empirical relationships between the reported yields and remotely sensed data, it could monitor crop yields over large areas.<\/jats:p>","DOI":"10.3390\/rs5115926","type":"journal-article","created":{"date-parts":[[2013,11,14]],"date-time":"2013-11-14T11:24:25Z","timestamp":1384428265000},"page":"5926-5943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":63,"title":["A Production Efficiency Model-Based Method for Satellite Estimates of Corn and Soybean Yields in the Midwestern US"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1146-4874","authenticated-orcid":false,"given":"Qinchuan","family":"Xin","sequence":"first","affiliation":[{"name":"Ministry of Education Key Laboratory for Earth System Modeling, and Center for Earth System Science, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Gong","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory for Earth System Modeling, and Center for Earth System Science, Tsinghua University, Beijing 100084, China"},{"name":"Department of Environmental Science, Policy and Management, University of California, Berkeley, Berkeley, CA 94720, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaoqing","family":"Yu","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory for Earth System Modeling, and Center for Earth System Science, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3115-2042","authenticated-orcid":false,"given":"Le","family":"Yu","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory for Earth System Modeling, and Center for Earth System Science, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Broich","sequence":"additional","affiliation":[{"name":"Plant Functional Biology and Climate Change Cluster Department, University of Technology Sydney, Broadway, NSW 2007, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Suyker","sequence":"additional","affiliation":[{"name":"School of Natural Resources, University of Nebraska-Lincoln, Lincoln, NE 68583, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ranga","family":"Myneni","sequence":"additional","affiliation":[{"name":"Department of Earth and Environment, Boston University, Boston, MA 02215, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"577","DOI":"10.1016\/j.gloenvcha.2010.07.001","article-title":"The poverty implications of climate-induced crop yield changes by 2030","volume":"20","author":"Hertel","year":"2010","journal-title":"Glob.
