Question about rain gauge
« on: November 06, 2018, 02:51:04 PM »
i have vantage pro2 plus Yesterday the precipitation was recorded station 24mm
But there is a manual scale close to my record 37 mm
Am I the most accurate? What is the most efficient standard manual or electronic?  :-)

Davis rain gauges are typically low without calibration but comparisons with other stations can be a bit deceptive. How far away is "close"

That is a significant distance. Those totals could be spot on.

The comparator is a manual scale and I am the one who owned it electronically (vantage pro2 plus)

If you had a manual gauge located right next to the Davis gauge, at the same height above ground, etc. -- then the manual gauge would be more accurate than the Davis gauge. 

Of course, you should then carefully, and exactly at every midnight, read the manual gauge, empty and dry it, re-install it, and record and report the manual gauge results for the preceding day.  [And do that very quickly, if it happens to be raining at midnight]

At 700 metres anything could be possible.
