To advance time series forecasting we need to progress on multiple fronts. In this thesis, we develop algorithms to identify causal relations which allow to identify the driving processes containing useful information for ...
This dissertation focuses on determining the vertical electron content distribution in low and high vertical resolution from ground-based and LEO on board GNSS data and improving the knowledge of ionosphere climatology in ...
A variety of morphodynamic patterns are typically present in the nearshore zone of sandy beaches that develop due to the interactions between waves, currents and the morphology. The most common are one or several nearshore ...
The occurrence of heat waves and cold spells has received special attention in recent years due to their impact on human health, ecosystems and economy. In the context of climate change, there is evidence that extreme ...
Precipitation is one of the most important, and also difficult to predict, elements of climate. This difficulty is associated with the transport of moisture through weather fronts that change their pathway, shape and ...
The research of this paper-based dissertation is focused on the Global Ionospheric Maps (GIMs) based on Global Navigation Satellite System (GNSS) including real-time combination, validation, time resolution and applications. ...
The dynamics of the climate system plays a crucial role in the sustainability of life on Earth, and this motivates research to understand and characterise our climate and predict its evolution. In this thesis we focus on ...
The study of stellar winds (SW) in the context of X-ray bursts (XRB) performed in this thesis has two main motivating issues. The first is whether or not the heavy elements produced from nucleosynthesis in XRBs can escape ...
The nearshore zone is plenty of 3D morphodynamic patterns resulting from the interaction of waves, currents and sediments. The dynamics of formation and evolution of these patterns is at present a controversial point in ...
In order to avoid the catastrophes caused by intense or even moderately intense, rainfall episodes, it is essential to have as exhaustive a knowledge as possible of the behaviour of the same. We have a source of information ...
Persistent Scatterer interferometry (PSI) is a group of advanced differential interferometric Synthetic Aperture Radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data ...
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
The research of this dissertation is studying the ionosphere by GPS radio occultation (RO) techniques. It is mainly divided into two parts. The first part focuses on the methodology in electron density profile retrievals ...
