Abstract: In the last year there has been an increasing interest for the 
analyisis of scalar and vectorâvalued random fields defined over space and 
time. Practitioners often deal with massive data sets for which estimation 
through maximum likelihood techniques becomes often unfeasible. Using 
compactly supported covariance function can allow to overcome such problem 
and tapering techiques have been proposed, in the past, in the context of 
scalarâvalued random fields defined over space only (Du, Zhang and 
Mandrekar, 2009). We believe that the extension of compact support to 
spaceâtime as well as to vectorâvalued random fields represents a 
considerable challenge from the mathematical viewpoint and an important 
tool for the statistical community. In this talk we present a personal 
selection of the results obtained in the last three years of research.
