Analysis of snow spatial and temporary variability through the study of terrestrial photography in the Trevelez river valley
Pérez Palazón, Mª José; Pimentel, Rafael; Herrero, Javier; Polo, María José (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 ... -
Climate Trends Impact on the Snowfall Regime in Mediterranean Mountain Areas: Future Scenario Assessment in Sierra Nevada (Spain)
Pérez Palazón, Mª José; Pimentel, Rafael; Polo Gómez, María José (MDPI, 2018)Snow constitutes a key component of the water cycle, which is directly affected by changes in climate. Mountainous regions, especially those located in semiarid environments, are highly vulnerable to shifts from snowfall ... -
Combining remote sensing and terrestrial photography in a snowmelt modeling framework to retrieve snow evolution in a semiarid region
Polo, María José; Herrero, Javier; Pimentel, Rafael; Pérez Palazón, Mª José; Gilabert, A.; Torralbo, Pedro (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 ... -
Comparison between Snow Albedo Obtained from Landsat TM, ETM+ Imagery and the SPOT VEGETATION Albedo Product in a Mediterranean Mountainous Site
Pimentel, Rafael; Aguilar Porro, Cristina; Pérez Palazón, Mª José; Polo Gómez, María José; Herrero Lantarón, Javier (MDPI, 2016)Albedo plays an important role in snow evolution modeling quantifying the amount of solar radiation absorbed and reflected by the snowpack, especially in mid-latitude regions with semiarid conditions. Satellite remote ... -
Extreme values of snow-related variables in Mediterranean regions: trends and long-term forecasting in Sierra Nevada (Spain)
Pérez Palazón, Mª José; Pimentel, Rafael; Herrero, Javier; Aguilar, Carmen; Perales, J.M.; Polo, María José (International Association of Hydrological Sciences, 2015)Mountain areas in Mediterranean regions constitute key monitoring points for climate variability and its impacts, but long time datasets are not always available due to the difficult access to high areas, relevant ... -
Integration of a Landsat Time-Series of NBR and Hydrological Modeling to Assess Pinus Pinaster Aiton. Forest Defoliation in South-Eastern Spain
Ariza Salamanca, Antonio Jesús; Navarro Cerrillo, Rafael M.; Bonet-García, Francisco J.; Pérez Palazón, Mª José; Polo Gómez, María José (MDPI, 2019) -
Validating improved-MODIS products from spectral mixture-Landsat snow cover maps in a mountain region in southern Spain
Pimentel, Rafael; Marín, Carlo; De Gregorio, Ludovica; Callegari, Mattia; Pérez Palazón, Mª José; Notarnicola, Claudia; Polo, María José (International Association of Hydrological Sciences, 2018)Remote sensing is the only feasible data source for distributed modelling of snow in mountain regions on medium to large scales, due to the limited access to these areas together with the lack of dense ground monitoring ...
