Discharge is estimated via a rating equation directly from the remote sensing data (M/C ratio) shown below.
Explanation:   Green line records upwelling microwave emission from within 5 km radius of a calbration land target; blue line is emission from within 5 km radious of the measurement target centered over the river.
Brown line is their ratio (M/C; 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. For calibration status, see "notes" entry, above.
