Interesting,
I have 4 gauges out, 2 stratus, 1 Davis vp2 and the 8" standard.
Did you have
any wind? Plays a big part.
The 2 stratus are 12' apart, E. & W. 1 is directly behind the Davis >6"<, the 8" is 100' + >W. away, out in the garden area.
Depending what way the wind is blowing, anything above 4 mph., the gauges will have a difference of up to 0.03-4". This amount will change in the gauges, relative to the wind direction and gauge location. It will even differ in the 6" distance, during a stout breeze, between the stratus and the Davis.
When the wind is 4 mph. and below,
all of the gauges will reflect the same measurement, as well as the eye can see.
The wind, gauge placement with respect to trees, fences, towers, masts-posts and structures play a big part in, is your rain measurement correct.
Any one else ever run a test program?
I use the one behind the Davis, as a constant, for reports to CoCoRaHAS.
