AB: Simple tipping bucket rain gauges were chosen for the NAME Rain Gauge Network in order to provide the maximum geographic coverage and density with the available funds. Unfortunately, it is well known that these gauges tend to underestimate rainfall, especially for high intensities. A simple methodology was developed and tested to correct these values using rainfall aggregated over different time intervals. These corrections are generally fairly small, but could be large for extraordinary rainfall rates. They are easy to implement using the event data and improve the results when compared to monthly rainfall recorded at manually operated gauges.
