## Not run
## To estimate the spatio-temporal variogram, paste and copy the following lines
## (without the symbol '#') in the console:
#
## vv_13 is obtained by running the function variogramST of the package gstat,
## as follows
#
# vv_13 <- gstat::variogramST(PM10~1, rr_13, width=60, cutoff = 220, tlags=0:15)
## End (Not run)
