A novel data fusion technique for snow cover retrieval
(2019)This paper presents a novel data fusion technique for improving the snow cover monitoring for a mesoscale Alpine region, in particular in those areas where two information sources disagree. The presented methodological ... -
Identifying the snow melting dynamics by exploiting the multi-temporal Sentinel-1 backscattering
(2019)Snow plays a key role in the hydrological cycle. Especially in mountain regions such as the Alps, snowmelt is the main responsible of run-off regimes, strongly influencing groundwater storage, flooding, avalanches, and ... -
Ecosystem Services in a Protected Mountain Range of Portugal: Satellite-Based Products for State and Trend Analysis
(2018)Mountains are facing strong environmental pressures, which may jeopardize the supply of various ecosystem services. For sustainable land management, ecosystem services and their supporting functions should thus be evaluated ... -
Soil Roughness Retrieval from TerraSar-X Data Using Neural Network and Fractal Method
(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 ... -
Review of Machine Learning Approaches for Biomass and Soil Moisture Retrievals from Remote Sensing Data
(2015)The enormous increase of remote sensing data from airborne and space-borne platforms, as well as ground measurements has directed the attention of scientists towards new and efficient retrieval methodologies. Of particular ... -
Analysis of movement rates and their association with precipitation and snow melt patterns: an example from the Corvara landslide, Italy
(2019)Landslides constitute serious geohazards in many hilly and mountainous regions and pose an important landscape forming process in South Tyrol, Italy. It is well recognized that water influx, originating from precipitation ... -
TITAN AS REVEALED BY THE CASSINI RADAR
(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 ... -
Estimating tree species diversity from space in an alpine conifer forest: The Rao's Q diversity index meets the spectral variation hypothesis
(2019)Forests cover about 30% of the Earth surface, they are among the most biodiverse terrestrial ecosystems and represent the bulk of many ecological processes and services. The assessment of biodiversity is an important and ... -
On the Automated Mapping of Snow Cover on Glaciers and Calculation of Snow Line Altitudes from Multi-Temporal Landsat Data
(2019)Mapping snow cover (SC) on glaciers at the end of the ablation period provides a possibility to rapidly obtain a proxy for their equilibrium line altitude (ELA) which in turn is a metric for the mass balance. Satellite ... -
A Fractal Algorithm for Surface Roughness Parameters retrieval using Multi -Band/polarization AIRSAR Data
(2019)Surface roughness is an important characteristic in analyzing SAR images and three-dimensional (3D) surfaces that influence the backscattering of electromagnetic waves. This paper proposes an algorithm based on a fractal ... -
Il progetto GreenRisk4Alps: Misure "verdi" per la gestione dei rischi naturali sulle Alpi
(2019)GreenRisk4ALPs: towards the implementation of ecosystem-based solutions for risk management in the Alps. Forests and mountain ecosystems play a crucial role in the mitigation of risks deriving from natural hazards in the ... -
Downscaling Land Surface Temperature from MODIS Dataset with Random Forest Approach over Alpine Vegetated Areas
(2019)In this study, we evaluated three different downscaling approaches to enhance spatial resolution of thermal imagery over Alpine vegetated areas. Due to the topographical and land-cover complexity and to the sparse ... -
Detection and Monitoring of Slow Slope Movement using Remote, Proximal and Ground Sensing in Alpine Regions: the ALPSMOTION Project
(2019)Deep-seated gravitational slope deformations as well as permafrost creep (i.e. rock glaciers) represent common geomorphological phenomena in high alpine areas. The systematic observation of changes over time caused by the ... -
A Methodology for Heterogeneous Sensor Data Organization and Near Real-Time Data Sharing by Adopting OGC SWE Standards
(2019)Finding a solution to collect, analyze, and share, in near real-time, data acquired by heterogeneous sensors, such as traffic, air pollution, soil moisture, or weather data, represents a great challenge. This paper describes ... -
Exploiting InSAR and multi-source data to study periglacial environments in the Alps at different space and time scales
(2017)The slope instability in alpine areas is a phenomenon related to superficial landslides, deep-seated gravitational slope deformations and permafrost creep. The systematic monitoring of changes over time caused by the slope ... -
Small Baseline Subset (SBAS) InSARAnalysis Using Sentinel-1 Data for Monitoring Landslide Deformation in the Alps
(2017)New generations of radar satellites (e.g. TerraSAR-X, Cosmo-SkyMed, Sentinel-1A/B) with short repeat-pass cycles and high spatial resolutions have enhanced the capabilities for acquiring data over large areas shortly after ... -
Cascading hazard risk assessment of a rockslide dam outburst flood in an alpine river basin
(2017)Earthquakes and heavy precipitation events represent the main triggering factors of mass movements such as landslides, rockslides or debris flows. The overall hazard potential is increased significantly if the mass ... -
INTEGRATION OF REMOTE SENSING WITH A HYDROCLIMATOLOGICAL MODEL FOR AN IMPROVED MONITORING OF ALPINE GLACIERS
(2018)In this work, we present a framework to integrate physically based hydroclimatological models and remote sensing products, by exploiting their advantages and overcoming their limitations, for an improved understanding and ... -
Interannual and subseasonal rock glacier displacement by exploiting different SAR techniques
(2018)Active rock glaciers are slow-moving, permafrost landforms that characterize high mountain periglacial terrains. Their complex movement, with interannual and subseasonal rhythms, are of interest for interpreting the evolution ... -
Relationship between Spatiotemporal Variations of Climate, Snow Cover and Plant Phenology over the Alps: An Earth Observation-Based Analysis
(2018)Alpine ecosystems are particularly sensitive to climate change, and therefore it is of significant interest to understand the relationships between phenology and its seasonal drivers in mountain areas. However, no alpine-wide ...
