A list of with three objects with the following components:
coords
the coordinates of the 22 spatial locations.
covariates
it is a 8052 by 3 matrix referring to the following covariates: intercept, emissions (g/s) and altitude (km). The first 366 rows refer to the first spatial location, the rows from 367 to 732 refer to the second spatial location and so on.
z
it is a 366 by 22 observation matrix referring to PM10 concentration measurements (log scale).
