Rainfall Sensor Calibration

Greetings all! I apologize if this has been discussed, but it is an issue that is frustrating…

Living here in FL near Orlando, we got a strong burst of rain yesterday - reports around my location were in the 1-3" range, and my station only recorded 0.68". While technically “possible” given the convective nature, I am quite confident this is a very low reading (Station 0.2mi away saw 1.77").

Any ideas or solutions here?

Thanks
Ed
