Parameters - Rain
Vantage Pro2 incorporates a tipping-bucket rain collector in the ISS that measures 0.01” for each tip of de bucket. A metric adapter can be installed to measure 0.2 mm for each tip of the bucket. Your station logs rain data in the same units it is measured in and converts the logged totals into the selected display units (inches or millimeters) at the time it is displayed. Converting at display time reduces possible compounded rounding errors over time.
Four separate variables track rain totals: “rain storm”, “daily rain”, “monthly rain”, and “yearly rain”. Rain rate calculations are based on the interval of time between each bucket tip, which is each 0.01” rainfall increment or 0.2 mm.
