    • Combined spatial and temporal effects of environmental controls on long-term monthly NDVI in the Southern Africa savanna 

      Campo Bescós, Miguel Ángel Upna; Muñoz Carpena, Rafael; Southworth, Jane; Zhu, Likai; Waylen, Peter; Bunting, Erin (MDPI, 2013)   Artículo / Artikulua  OpenAccess
      Deconstructing the drivers of large-scale vegetation change is critical to predicting and managing projected climate and land use changes that will affect regional vegetation cover in degraded or threated ecosystems. We ...
    • Comparison between capacitive and microstructured optical fiber soil moisture sensors 

      López Aldaba, Aitor Upna; López Torres, Diego Upna; Campo Bescós, Miguel Ángel Upna; López Rodríguez, José Javier; Yerro Lizarazu, David; Elosúa Aguado, César Upna; Arregui San Martín, Francisco Javier Upna; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel Upna (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ...
    • Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles 

      Lievens, Hans; Vernieuwe, Hilde; Álvarez Mozos, Jesús Upna; Baets, Bernard de; Verhoest, Niko E. C. (MDPI, 2009)   Artículo / Artikulua  OpenAccess
      In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ...
