260-953 Alter-Type Wind Screen for
Tipping Bucket Rain Gages
1. Introduction
The 260-953 is a wind screen for our tipping bucket rain gages that can
minimize the effect of strong winds on the rain measurements. It includes 32
leaves that swing as the wind moves past them. The leaves are evenly spaced
on a 48-in.-diameter ring. The ring is comprised of four quadrants. Each
quadrant mounts onto posts made of galvanized-steel pipe.
The 260-953 should be installed so that the top edge of the rain gage funnel is
1/2 in. to 1 in. below the top edge of the wind screen leaves. Typically, the
wind screen is mounted onto the concrete pad that also supports the rain gage.
However, concrete piers or wooden supports can also be used. To function
properly, both the rain gage and wind screen need to be installed correctly.
