TL;DR: This blending of different sources of prediction is verified for different types of episodes (convective, moderately convective and stratiform) to obtain a robust methodology for implementing it in an operational and dynamic way.

TL;DR: In this article, the authors present average and extreme propagation conditions in the coastal area of Barcelona (NE Spain) calculated using three years of radiosonde data, related to local prevailing circulations such as the sea breeze with particular interest in the nearby Vallirana weather radar.

TL;DR: In this article, a pilot project was carried out in Terres de Ponent, an area of about 200,000 ha in Lleida (Catalonia), in the NE of the Iberian Peninsula, to characterise hail events, directly by radiosounding data and radar images, and indirectly by the evaluation of the radiosonde forecasted by the NWP Mesoscale Atmospheric Simulation System (MASS).

TL;DR: In this article, the role of citizen science and crowd sourced observations in the monitoring of snowfall events with surface precipitation phase discrimination at the ground level using data interpolated from a network of automatic weather stations covering an area of complex terrain.

TL;DR: In this article, more than one hundred radiosonde ascents are examined to evaluate the occurrence of anomalous propagation (AP) of microwave radiation at the coastal site of Barcelona (Spain). Temperature and humidity profiles are used to calculate refractivity gradients and to estimate the existence of ducting layers.
