Rainfall total 3.45", but it could be 3.359". This is a two watch problem.

I have a weather station now, mounted up on the roof, with a wireless remote readout down in the comfort of the home.  It was a gift from Juli - Thanks hon!  I'm in the midst of figuring out how it's calibrated against my tried and true rain gauge. 

Here's the three first trials, broken down by storm:

Weather station 3/10: 0.39" + 3/11 (thus far) 0.18" = 0.57"
Rain gauge 0.69"

Weather station 3/14: 0.21" + 3/15: 0.12 = 0.33"
Rain gauge 3/16 0.3" (upon return from trip, so perhaps evaporation explains the difference)

Weather station 3/17: 0.009"
Rain gauge 3/17: 0.01"

That 3/10 storm didn't have close agreement, which was weird given the much closer tracking of the following two.  I checked for operator error a couple times, but without any mistakes found and I don't recall an errant jet of water from the hose.

This puts my backyard rainfall at 3.359" (weather station) of 3.45" (rain gauge) which brings to mind a favorite saying of mine, "Only the man with two watches doesn't know what time it is."

  1. Wow, so thus far this season you only have under four inches of rain and April is just around the corner ??? Spooky, when I come April 11th to LAX and we rent a car to drive to my mum's place in El Cajon in San Diego County, I'm going to have to do some water deep soaking for certain plants down there. All that freezing cold and zilch.
