Three Years of Country-Wide Rainfall Maps from Cellular Communication Networks
TL;DR: In this article, the authors proposed a real-time approach to retrieve the space-time dynamics of rainfall for an entire country (The Netherlands, ∼35,500 km2), based on an unprecedented number of links (∼2,400) and a rainfall retrieval algorithm that can be applied in real time.
Retrieval algorithm for rainfall mapping from microwave links in a cellular communication network
TL;DR: In this article, the authors used microwave links from cellular communication networks as an alternative or complementary means for continental-scale rainfall monitoring and provided a detailed description of the employed rainfall retrieval algorithm.

Climatic features of atmospheric stability in the Mediterranean region (1948–2006): spatial modes, inter-monthly and inter-annual variability
TL;DR: In this paper, the predominant spatial modes of atmospheric stability over the Mediterranean region are revealed by applying factor analysis and cluster analysis on the daily 2.5° × 2° grid point values of K-index for the period 1948-2006.
