Researchers have introduced M-CaStLe, an advancement of the CaStLe meta-algorithm designed for discovering causal structures in complex multivariate space-time gridded data. This new method extends previous univariate capabilities to jointly model causal relationships both within and across variables in these high-dimensional datasets. M-CaStLe achieves this by constraining parent identification to local space-time neighborhoods, thereby increasing effective sample size and making discovery more tractable. The algorithm has been evaluated across various settings, including physical simulations and climate data, demonstrating improved accuracy in recovering causal structures and identifying key dynamics.
