My weather station is an Oregon Scientific WMR-968 (wireless). Virtual Weather Station running on my PC. The instruments are mounted on a 4-by-4 with ledges for the tipping-bucket rain gauge and hygrothermometer. Both are at 6 feet. I originally had some trouble with afternoon temperature running around 4 degree F above the surrounding observations, but built a shelter with a solar fan that starts spinning after sunrise and stops at sunset. The aspiration has improved the temperature errors.

The anemometer is positioned at 11.5 feet. An 8" rain gauge is positioned about 10 feet away for verification and backup of the tipping bucket. A 4" rain gauge is on the other side of my backyard (200 feet to the south) which also helps to verify rainfall and provide backup. A max-min alcohol thermometer is mounted on the north side of the 4-by-4 at the 6 foot level. The only obstructions are from the west where our home and some trees are located.
