Hydrologic status: 2 Normal flow Total runoff this year: 197 mm
Latest M/C ratio: 1.01 Seven day total: 1 mm
Estimated current discharge: 81 m3/sec Percent of mean 7-day total: 42.9 % (today's value compared to mean for same period, 2003-2007)
Ice-cover determination: 5 yr recurrence flood: 237 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow, 2 = Normal flow, 3 = Flood, 4 = Major Flood 217 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Clinton, Iowa (4119650)         Contributing Area:   sq mi 221704 sq km
(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Discharge calibration is based on comparision of monthly means, minima, and maxima from a ground comparision station in the region with adjustment for different contributing areas
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.
