(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Comparison station is placeholder, only; this site is not yet calibrated to actual discharge
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)
(For U.S, sites, nearby ground station discharge may also be shown)

Discharge is estimated directly via a rating equation from the remote sensing data (M/C ratio) shown below.
Explanation:   Green line records upwelling microwave emission from a land parcel (ca 10 km x 10 km) near the river; blue line from a parcel 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.
When data above show calibration site values lower than for the measurement site, discharge estimation may not be possible.
