Romania - getting ready for weather report

As soon as we came back from the London meeting, we spoke to the pupils about the WIKI "weather journal" and we formed some groups who would be in charge of this activity. Right in front of the school they have put the rain measuring devices and the thermometre. The physics/chemistry teacher, Viorica Cortojan explained to the students how, how often and when to measure the temperature and the quantity of precipitations.
What if it rains at night and especially if it pours? We could approximate, I suppose. Or search other "sources".
