Sometimes we get into to a routine that with checking our rain gauges and recording our data that we forget to check the reliability and accuracy of our data. Reliable data is that in which the methods used for gathering it yields consistent results. Accurate data is data that is correct. Reliability and accuracy can be compromised if your rain gauge is not set up properly. Maybe everything is in order in terms of placement and cleanliness when you first set up your rain gauge but over time, all sorts of things can happen that can compromise your data. Here's a check list to make sure your getting reliable and accurate data from your gauge.
- Is your rain gauge still located in an open area? (No structures, tress or brush surrounding it)
- Does your rain gauge have gunk in it? (bird poop, debris, algae)
- Is the post on which your rain gauge sit straight?(Warped wood, bent metal)
- Is your rain gauge straight? (Not lose or leaning. Measure with bubble level)
- Is it far enough off the ground? (2 feet off the ground in open areas, 2 in developed areas)
So, check your gauge to make sure all to make sure you're getting reliable, accurate data. For more information about the correct placement of your gauge, view
