Today we did not catch rain, but we got the big bang!

I took this picture this afternoon on the roof of École des Ponts where three disdrometers are currently being tested. Such device provides information on the size and velocity of each rain drop passing through a sampling area of roughly 50 cm2. In the future they will be used to validate the polarimetric data of the radar that will shortly be installed in Marne-la-Vallée.
