Great! They were moving on. Adi listened to Flamsteed explain the necessary stuff and what not. Eyeing the bottom of the radiosonde, he did see the the clamp. Push it to detach the radio thingy? You got it. Grasping the radiosonde, Adi did just that.

That done, he bustled over to a window, threw it open and dropped the balloon out. But not before being his with the cold from outside. Brrr! Backing away from the window, which he had closed (but still, it felt like he hadn't done that at all), Adi glanced at the receiver. The precipitation temperature to be precise.

Ah yes. Here was a reading. -19 degrees Celsius.
