Where it's located
The weather radar is the impressive large soccer ball shaped object located on the top of the ship.
What the weather radar is used for
The weather radar sends and receives microwave pulses to collect atmospheric data. This data is used to improve climate models and weather predictions for Australia.
How it works
It's capable of gathering data anywhere in a 150 kilometre radius around the ship: from clouds towering 20 kilometres over the tropical ocean—to cold ice storms in the Antarctic.
The pulse has a vertical and horizontal signal, called dual polarisation. The returning signal reveals the quantity, location, size and shape of any precipitation - water, snow or ice.
