Functions to read some data as provided by Arpa Emilia-Romagna

read.qaria (file) 
read.sql   (file) 
qaria2long (datafiles, anafile, codes=NULL)

read.ncdf.arpaer(con=NULL, pollutant="pm10", lev=1, 
                 tz.in="UTC", tz.out="Africa/Algiers")
read.grads(filectl) 

read.field(file, coords.col=1:2, data.col=3, coords.fact=1, ...)

`file`	name of the input file
`datafiles`	vector of names of files (format 'estra_qaria', an internal standard for some people in Arpa-ER)
`anafile`	file with stations metadata
`codes`	vector with stations codes, if `NULL` it is argued from the elements of `datafiles`, if they are in the form /path/to/files/pollutant_stationcode.asc
`con`	name of a NetCDF file, or an already open connection to NetCDF
`pollutant`	pollutant code used in the NetCDF
`lev`	level
`tz.in`	timezone used by the CTM
`tz.out`	timezone used for the observed data
`filectl`	name of the GrADS ctl file
`coords.col`	a vector with the numbers of the columns containing the coordinates
`data.col`	a scalar with the number of the column containing the data
`coords.fact`	multiplication factor for coordinates (e.g. 1000 if you need to convert kilometers to meters)
`...`	optional arguments; will be passed to `read.table`, called by `read.field`

If your input data are not provided following internal 'standard' formats of Arpa-ER, you don't need these functions, except maybe read.field, which is quite general. Then, you'll need to write your own reading functions, suitable for your data format.

The function read.grads is deprecated, since I wrote it when I was young, and it needs external executables.
