Question: I am an Italian student, and I'm looking for a particular dataset.

I'm interested in a model for spatial regression, with time-varying data. I'm looking for data with coordinates, measured in different moments for each point. Where can I find them?

I don't have a specific request for the dataset. I need to try a statistical model. This model works with data spatially distributed (so every datum is located with his coordinates), and for every point (located by the coordinates) I need more measurements, at different times.

I leave an example. I'm measuring the temperature at different points of my city during the day. I'm interested in two points: the center (coordinates...) and near the river (coordinates...). Data are measured hourly. So I have (starting from 8:00):

Center: 25C, 27C, ...

River: 22C, 24C, ...

Answer: 
You could look for climate data on the open data portals around Italy, Regione Liguria has it for meteorogical measurements (<http://www.cartografiarl.regione.liguria.it/SiraQualMeteo/Fruizione.asp>) but doesn't have an API.
