Always bear in mind that AWS rain-gauges typically collect up
to 10% less rain than a standard manual gauge. Sometimes the
difference is even greater. I'd always recommend having a
manual gauge alongside an AWS one.


Philip,

Why is that - is it just a calibration thing ? I often have to amend the AWS
figure after the event with the rain-guage value.
