To understand the early Martian climate, the volume of the global Martian valley network is required. Here, the authors use a black top hat transformation method and find that the minimum global valley network volume is 1.74 × 1,014 m3 with a minimum cumulative volume of water required of 6.86 × 1,017 m3.
