Jorge, I did a very similar thing with some air modeling data. The spatial features were vector 'grid' cells. I stored these in PostGIS. For each feature, there was one data measurement for each day of the year and some additional aggregated data values. I stored this data as related tables in the same database.
To create animations, I used MapServer to create the individual image slices. I used a URL variable to pass each individual date in to MapServer. MapServer incorporated that value into a query where condition used to pull data from PostGIS, and then it built the associated image. David.
