Step 1: Identify the standard non-recording raingauge. The prevalent non-recording raingauge, especially within the Indian Meteorological Department (IMD), is the Symon's raingauge.
Step 2: Detail its components. It comprises a funnel with a 127 mm (5 inches) diameter circular collecting area, channeling rainwater into a glass receiving bottle. This bottle's volume is sufficient to contain the rainfall collected by the funnel.
Step 3: Specify the capacity. The receiving bottle is engineered to hold a defined quantity of rainfall before requiring emptying. Its standard capacity equates to 10 cm (or 100 mm) of rainfall over the collection area. Rainfall is measured by transferring the collected water into a calibrated measuring cylinder.
