Abstract

A forest canopy forms a critical platform for complex interactions between the vegetation and the atmosphere boundary layer and is considered as a crucial piece for environmental scientists in their understanding of the ecosystem and its response to the climate change. Microfronts represent a class of these interactions characterized by a moving mass of air that introduce uctuations in ambient temperature and humidity on small spatial and temporal scales. In this paper, we present a joint spatio-temporal hidden markov model that simultaneously incorporates neighborhood dependencies in space and time. We show that our approach can trace the diffusion of microfronts more effectively than several baseline methods over a sensor data from Brazilian rainforest and a synthetically generated dataset.
