Estimating snow albedo patterns in a Mediterranean site from Landsat TM and ETM+ images
(SPIE, 2013)
The albedo of snow affects the shortwave radiative flux at the land-atmosphere interface, so that it therefore plays an important role in the snow mass and energy balance. In semiarid areas, their particular climate ...
Study of snow dynamics at subgrid scale in semiarid environments combining terrestrial photography and data assimilation techniques
(American Meteorology Society, 2015)
Snow cover simulation is a complex task in mountain regions because of its highly irregular distribution. GIS-based calculations of snowmelt–accumulation models must deal with nonnegligible scale effects below cell size, ...
Subgrid parameterization of snow distribution at a Mediterranean site using terrestrial photography
(EGU, 2017)
Subgrid variability introduces non-negligible scale
effects on the grid-based representation of snow. This heterogeneity
is even more evident in semiarid regions, where the
high variability of the climate produces various ...
Analysis of snow spatial and temporary variability through the study of terrestrial photography in the Trevelez river valley
(SPIE, 2014)
The spatiotemporal evolution of the snow cover may help to obtain conclusions on the variability of the atmospheric agents in high mountain areas. That evolution is difficult to analyze due to the heterogeneity of the snow ...
Combining remote sensing and terrestrial photography in a snowmelt modeling framework to retrieve snow evolution in a semiarid region
(IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018)
This work shows the strength of combining different data sources and modelling to generate long time map series of snow variables in Sierra Nevada (Spain), an alpine environment within a semiarid region in which the snowpack ...
Snow evolution in a semi-arid mountainous area combining snow modelling and Landsat spectral mixture analysis
(Copernicus, 2015)
This study proposes the use of both physically-distributed hydrological modelling in combination with satellite remote sensing images, to study the evolution of the snowpack in the Sierra Nevada mountains, in southern ...
Field Resistance to Verticillium Wilt in Selected Olive Cultivars Grown in Two Naturally Infested Soils
(The American Phytopathological Society, 2013)
The resistance of 11 olive cultivars to Verticillium dahliae was assessed in two experimental field trials. One-year-old rooted olive cuttings from the World Olive Germplasm Bank (IFAPA research center, Córdoba, Spain) ...
Looking for variable molecular markers in the chestnut gall wasp Dryocosmus kuriphilus: first comparison across genes
(Frontiers, 2018)
The quick spread of the chestnut gall wasp Dryocosmus kuriphilus in Europe constitutes an outstanding
example of recent human-aided biological invasion with dramatic economic losses. We screened for
the first time a set ...
Variability and selection of verticillium wilt resistant genotypes in cultivated olive and in the Olea genus
(2015)
Developing verticillium wilt resistant genotypes is currently a major objective in olive breeding. In this study, 6017 genotypes derived from 48 crosses obtained by open pollination and crosses between olive cultivars, ...
Effective inoculation methods to screen for resistance to Verticillium wilt in olive
(2013)
Effective inoculation methods to screen for Verticillium wilt resistance are essential for the development of olive cultivars resistant to this devastating disease. Three inoculation methods, pot immmersion, bare-root ...
