How is rain measured
  • 1 answers

Amar Kumar 7 years, 11 months ago

The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.

Most rain gauges generally measure the precipitation in millimetres equivalent to litres per square metre. The level of rainfall is sometimes reported as inches or centimetres. Rain gauge amounts are read either manually or by automatic weather station (AWS).
