Latest measurement: 3-Aug-10 Mean annual runoff: 673 mm (2003-2009)
Hydrologic status: 3 Flood Total runoff this year (2010): 401.0 mm
Latest M/C ratio: 2.25 Seven day total: 32.7 mm
Estimated current discharge: 27384 m3/sec Percent of mean 7-day total: 113.0 % (today's value compared to mean for same period, 2003-2009)
5 yr recurrence flood: 32841 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow or ice, 2 = Normal flow, 3 = Flood, 4 = Major Flood 31937 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Mandi Plain (2839100)         Contributing Area:   sq mi 20886 sq km
(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Calibration to discharge has been accomplished. Accuracy Estimate: Good Comparison station drains much smaller watershed.
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)

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.
