Zoomed in of previous Website: http://indiawbg.rap.ucar.edu/precip/ -- 5 day accumulations also available, and differing centers and lead-times

Zooming in and clicking on a station Native values shown in plot on the left; quality controlled on the right

“Rating curve” fits http://indiawbg.rap.ucar.edu/Ratefit/

Optimal lagged “rating curve” Optimal lagged rating curve for one station lower down in the Brahmaputra, with curser giving individual points

Same site as previous, but arbitrary lag Same site as previous – arbitrary lag greatly increases the rating curve fit “error”

Another site higher up in basin Rating curve higher up in basin and along a smaller tributary – notice the increased “error”

Reports, maps, and data directories provided here

Gaging sites river discharge estimates Looking under “AllPlots/” find individual plots of associated discharge at each river stage gaging sits

Access to individual data files also made available Data also provided under our FTP site
