    • Soil Roughness Retrieval from TerraSar-X Data Using Neural Network and Fractal Method 

      Maleky M; Amini J; Notarnicola C (2019)
      The purpose of this study is to estimate the surface roughness (rms) using TerraSar-X data in HH polarization. Simulation of data is carried out at a wide range of moisture and roughness using the Integral Equation Model ...
    • Spatio-temporal population modelling as improved exposure information for risk assessments tested in the Autonomous Province of Bolzano 

      Renner K; Schneiderbauer S; Pruß F; Kofler C; Martin D; Cockings S (2017)
      Population data is commonly available for administrative units referring to the year of the last census. That level of aggregation and the static character of the information pose particular difficulties for spatial ...
    • Strategies to improve the explanatory power of a dynamic slope stability model by enhancing land cover parameterisation and model complexity 

      Schmaltz EM; Van Beek LPH; Bogaard TA; Kraushaar S; Steger S; Glade T (2019)
      Despite the importance of land cover on landscape hydrology and slope stability, the representation of land cover dynamics in physically based models and their associated ecohydrological effects on slope stability is rather ...
    • Synergetic use of Sentinel-1 and Sentinel-2 data for soil moisture mapping at plot scale 

      Attarzadeh R; Amini J; Notarnicola C; Greifeneder F (2018)
      This paper presents an approach for retrieval of soil moisture content (SMC) by coupling single polarization C-band synthetic aperture radar (SAR) and optical data at the plot scale in vegetated areas. The study was carried ...
    • TITAN AS REVEALED BY THE CASSINI RADAR 

      Lopes RMC; Wall SD; Elachi C; Birch SPD; Corlies P; Coustenis A; Hayes AG; Hofgartner JD; Janssen MA; Kirk RL; Legall A; Lorenz RD; Lunine JI; Malaska MJ; Mastroguiseppe M; Mitri G; Neish CD; Notarnicola C; Paganelli F; Paillou P; Poggiali V; Radebaugh J; Rodriguez S; Schoenfeld A; Soderblom JM; Solomonidou A; Stofan ER; Stiles BW; Tosi F; Turtle EP; West RD; Wood CA; Zebker HA; Barnes JW; Casarano D; Encrenaz P; Farr T; Grima C; Hemingway D; Karatekin O; Lucas A; Mitchell KL; Ori G; Orosei R; Ries P; Riccio D; Soderblom LA; Zhang Z (2019)
      Titan was a mostly unknown world prior to the Cassini spacecraft’s arrival in July 2004. We review the major scientific advances made by Cassini’s Titan Radar Mapper (RADAR) during 13 years of Cassini’s exploration of ...
    • Titan’s “Magic Islands”: Transient features in a hydrocarbon sea 

      Hofgartner JD; Hayes AG; Lunine JI; Zebker H; Lorenz RD; Malaska MJ; Mastrogiuseppe M; Notarnicola C; Soderblom JM (2016)
      The region of Titan's hydrocarbon sea, Ligeia Mare, where transient bright features were previously discovered, was anomalously bright in the first of two more recent Cassini RADAR observations but not the second. Another ...
    • Two-source energy balance modeling of evapotranspiration in Alpine grasslands 

      Castelli M; Anderson M; Yang Y; Wohlfahrt G; Bertoldi G; Niedrist G; Hammerle A; Zhao P; Zebisch M; Notarnicola C (2018)
      This work aims to assess a diagnostic approach which links evapotranspiration (ET) to land surface temperature (LST) measured by thermal remote sensing in the Alps. We estimated gridded ET, from field (30 m) to regional ...
    • Uncertainty analysis of gross primary production upscaling using Random Forests, remote sensing and eddy covariance data 

      Tramontana G; Ichii K; Camps-Valls G; Tomelleri E; Papale D (2015)
      The accurate quantification of carbon fluxes at continental spatial scale is important for future policy decisions in the context of global climate change. However, many elements contribute to the uncertainty of such ...
    • An Unsupervised Method to Detect Rock Glacier Activity by Using Sentinel-1 SAR Interferometric Coherence: A Regional-Scale Study in the Eastern European Alps 

      Bertone A; Zucca F; Marin C; Notarnicola C; Cuozzo G; Krainer K; Mair V; Riccardi P; Callegari M; Seppi R (2019)
      Rock glaciers are widespread periglacial landforms in mountain regions like the European Alps. Depending on their ice content, they are characterized by slow downslope displacement due to permafrost creep. These landforms ...
    • Validation of SMAP surface soil moisture products with core validation sites
