Query: Spatiotemporal large-scale networks shaped by air mass movements   The movement of atmospheric air masses can be seen as a continuous and
complex flow of particles hovering over our planet. It can however be locally
simplified by considering three-dimensional trajectories of air masses
connecting distant areas of the globe during a given period of time.
  In this paper, we present a mathematical framework to construct spatial and
spatiotemporal networks where the nodes are the subsets of a partition of a
geographical area and the links between these nodes are inferred from sampled
trajectories of air masses passing over and across the nodes. We propose
different estimators of link intensities relying on different bio-physical
hypotheses and covering adjustable time periods. This approach leads to a new
class of spatiotemporal networks characterized by adjacency matrices. We
applied the approach in two real geographical contexts: the watersheds of the
French region Provence-Alpes-C\^ote d'Azur and the coastline of the
Mediterranean Sea. The analysis of the constructed networks allowed identifying
a marked seasonal pattern in air mass movements in the study areas.
  These constructed networks can be used to investigate issues, e.g., in
aerobiology and epidemiology of airborne plant pathogens. Similar networks
could be estimated from other types of trajectories, such as animal
trajectories.
