According to climate projections for the end of the twenty-first century, regional responses to global warming include a strong and widespread drying over the northern Mediterranean, particularly intense in summer. Many ...
High-mass binary systems involve extreme environments that produce non-thermal emission from radio to gamma rays. Only three types of these systems are known to emit persistent gamma-ray emission: colliding-wind binaries, ...
Air pollution is a major environmental and public health concern, especially in urban areas where both emission sources and population are concentrated. The pollution sources and the evolution of aerosols and gaseous ...
The atmospheric boundary layer in stably-stratified conditions and over non-homogeneous terrain becomes a complex system with many interactions of physical processes occurring in a wide range of different spatial and ...
Gaia is an extremely ambitious astrometric space mission adopted within the scientific programme of the European Space Agency (ESA) in October 2000. It aims to measure with very high accuracy the positions, motions and ...
Current technology allows the proliferation of multiple forecast systems developed by different research institutions from all over the world. However, most decision makers need a reliable probabilistic prediction instead ...
Aquesta tesi doctoral se centra en l'estudi de la contaminació lumínica tant en zones urbanes com en zones protegides de Catalunya. S'entén per contaminació lumínica qualsevol efecte advers produït per la llum artificial ...
The investigation of climate variability in different timescales such as daily, monthly, seasonal and inter-annual has utmost importance for managing the socio-economic processes on regional to global scale. Indeed, the ...
In this work, a subsynoptic characterization of tropopause fold structures is derived from one-year of global, high resolution GFS (Global Forecasting System, 0.3 degrees) data analyses and 10 years of daily WRF (Weather ...
In this Thesis, we show how the properties of dark matter halos can be directly derived from the proper filtering of the primordial density field through the use of the CUSP formalism (ConflUent System of Peak trajectories). ...
This thesis studies the benefits of different calibration approaches on seasonal forecasting and the improvement of seasonal prognosis of water resources and forest fires. Droughts and wildfires are an inherent problem to ...
Gamma-ray binaries are systems that comprise a compact object orbiting a companion star and display the maximum of the non-thermal Spectral Energy Distribution (SED) in gamma rays. Currently we know five gamma-ray binaries. ...
