Our infrastructure is being built based on past climate data

Was that because the data was not actually peak _instantaneous_ rain rates, but rather rates averaged over a period of time (likely hours or longer)?

Seems like microwave links would be most sensitive to instantaneous rate along specific paths, but any historical data would be measuring accumulated precipitation (averages over time) at specific locations.

This is true -- most vendors supply a calculator tool that attempts to take this into consideration. Over the past 10yrs or so I've found them to be generally accurate, but have noticed a significant deviation in late 2019-2020 from expected vs observed effects.

I don't know what method is used but would expect it to be some sort of extrapolation from the average to predict peak rates
