In order to overcome the coherent superposition of the backscattering contributions from vegetation and underlying soils, a simplification of an existing polarimetric decomposition is proposed in this study. It aims to retrieve the soil moisture by using only the surface scattering component, once the volume scattering contribution is removed. Evaluation of the proposed simplified algorithm is performed using extensive ground measurements of soil and vegetation characteristics and the time series of UAVSAR (Uninhabited Aerial Vehicle Synthetic Aperture Radar) data collected in the framework of SMAP (Soil Moisture Active Passive) Validation Experiment 2012 (SMAPVEX12). The retrieval process is tested and analyzed in detail for a variety of crops during the phenological stages considered in this study. The results show that the performance of soil moisture retrieval depends on both the crop types and the crop phenological stage. Soybean and pasture fields present the higher inversion rate during the considered phenological stage, while over canola and wheat fields, the soil moisture can  be retrieved only partially during the crop developing stage. RMSE of 0.06\u20130.12 m3\/m3 and an inversion rate of 26%\u201338% are obtained for the soil moisture retrieval based on the simplified polarimetric decomposition.<\/jats:p>","DOI":"10.3390\/rs8020142","type":"journal-article","created":{"date-parts":[[2016,2,10]],"date-time":"2016-02-10T10:08:25Z","timestamp":1455098905000},"page":"142","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Evaluation of Simplified Polarimetric Decomposition for Soil Moisture Retrieval over Vegetated Agricultural Fields"],"prefix":"10.3390","volume":"8","author":[{"given":"Hongquan","family":"Wang","sequence":"first","affiliation":[{"name":"Centre d\u2019applications et de Recherches en T\u00e9l\u00e9d\u00e9tection (CARTEL), Universit\u00e9 de Sherbrooke, Sherbrooke, QC J1K2R1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramata","family":"Magagi","sequence":"additional","affiliation":[{"name":"Centre d\u2019applications et de Recherches en T\u00e9l\u00e9d\u00e9tection (CARTEL), Universit\u00e9 de Sherbrooke, Sherbrooke, QC J1K2R1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalifa","family":"Goita","sequence":"additional","affiliation":[{"name":"Centre d\u2019applications et de Recherches en T\u00e9l\u00e9d\u00e9tection (CARTEL), Universit\u00e9 de Sherbrooke, Sherbrooke, QC J1K2R1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1760-2425","authenticated-orcid":false,"given":"Thomas","family":"Jagdhuber","sequence":"additional","affiliation":[{"name":"Microwaves and Radar Institute, German Aerospace Center, Oberpfaffenhofen 82234, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irena","family":"Hajnsek","sequence":"additional","affiliation":[{"name":"Microwaves and Radar Institute, German Aerospace Center, Oberpfaffenhofen 82234, Germany"},{"name":"Institute of Environmental Engineering, Swiss Federal Institute of Technology Zurich,  Zurich 8093, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"442","DOI":"10.1109\/TGRS.2008.2009642","article-title":"Potential of estimating soil moisture under vegetation cover by means of PolSAR","volume":"47","author":"Hajnsek","year":"2009","journal-title":"IEEE Trans.
