[gradsusr] Templating using split data

you could:
 * avoid spitting: a single dataset. After 120hr you will have valid
   data, undef, valid data, and so on, but it should work
 * split the dataset replicating the last record of first dataset
   (120hr) into the second one, it should work

Hoping it could help
bye bye

Attenzione ARPAL ha cambiato indirizzi digitali, i nuovi indirizzi di e-mail sono composti dall'attuale nome.cognome seguito da @arpal.liguria.it, quindi nome.cognome at arpal.liguria.it
