The main objective of this work is to study and optimize the amorphous silicon deposited in a PECVD reactor of recent acquisition, making it suitable for thin film and c-Si based solar cells. Optimization of intrinsic ...
L’orografia té un impacte molt important en la circulació del vent i en la precipitació a totes les escales, des de la microescala fins a la macroescala. La complexitat i la singularitat de les interaccions entre el relleu ...
In 2009, the Spanish Ministry of Science and Innovation approved a proposal to modify the Global Positioning System (GPS) receiver and to allocate a Polarimetric (Pol) Radio Occultation (RO) antenna in the Spanish PAZ ...
Precipitation phase discrimination at ground level constitutes a fundamental variable in many meteorological and hydrological applications, including avalanche hazards, winter road safety, and flooding from rain on snow ...
Weather radar data and its downstream products are essential elements in weather surveillance and key parameters in the initialisation and validation of hydrological and meteorological models, among other downstream ...
Natural disasters of hydro-meteorological origin are the biggest risk worldwide. In Catalonia (NE of the Iberian Peninsula), severe weather and flash floods occur each year, resulting in major damage to property, losses ...
[eng] Global energy use has increased, causing a rapid shift in the climate. Renewable energy sources such as solar energy must replace fossil fuels to slow down this trend. In order to achieve this, the amount of power ...
The radiative transfer cannot be explicitly resolved in the atmospheric models for two reasons: i) a full treatment of the radiative transfer equation (RTE) requires a high amount of computational resources and ii) the ...
Tornadoes are the meteorological phenomenon which can produce the strongest surface wind on Earth, causing damage, injuries and fatalities. Several studies show that severe storm environments could be more frequent due to ...
The use of femtosecond lasers has recently gained attention as a result of the recognition to Gérard Mourou and Donna Strickland with the award of the Nobel Prize in Physics 2018 "for their method of generating high-intensity, ...
