Spatio-temporal modelling has become in the recent years one of the most important areas for research in relation to statistical analysis of natural processes, and especially processes involved in environmental studies. Literature is growing with contributions in many directions, from theoretical to methodological or applied research work. The understanding and proper definition of this area as a scientific discipline requires an important effort on synthesis of this body of knowledge, useful for the establishment of both solid theoretical foundations and well-based methodological approaches which are accessible and useful to researchers and practitioners.

The Spanish Workshop on Spatio-Temporal Modelling of Environmental Processes (under acronym 'METMA', for 'Modelización Espacio-Temporal de Procesos Medio-Ambientales') was iniciated (Benicassim, Spain, 2001) by Profs. Jorge Mateu and Francisco Montes (University Jaume I, Castellon, Spain). The aim was to create an open forum for exchange and discussion between researchers working in this area, with participation of active groups from Spain and other countries.

In the same spirit, the Second Edition (METMA'04) is organized and will be held on June 1-3, 2004, in Granada (Spain). As in the previous edition, the number of participants has been limited to about 70 scientists, including invited speakers, contributing authors (with oral or poster presentations) and general audience. Lectures and presentations will take place at Hotel Granada Center (next to the Faculty of Sciences and 5 minute walk to the city center).
