TWP/SMET/C3 - Negative rainfall rates
Due to limitations of the Zeno dataloggers all voltage measurements from the optical rain gauge (ORG) were converted to rainfall rates. This resulted in negative values for rain rates. Any value below 0.10 mm/hr should be considered to be 0 mm/hr. New dataloggers alleviated this problem.
Consider rainfall rate data less than 0.10 mm/hr as 0.0 mm/hr
