Discharge is estimated via a rating equation directly from the remote sensing data (M/C ratio) shown below.

Green line records upwelling microwave emission from within 5 km radius of a calbration land target.

Explanation:

Blue line is emission from within 5 km radius of the measurement target centered over the river.

Brown line is their ratio (M/C; "HR" in Brakenridge et al 2007; scale on right) and is used to estimate river discharge via a rating equation.

Rating equations are being developed and applied on an individual basis using available ground-based discharge information.
