Hard surfaces can cause errors in precipitation measurements due to splash-in.
Also avoid placing the instruments on steep slopes or in sheltered hollows unless such terrain represents the surrounding area. Do not place the rain gauge and instrument shelter close to buildings, trees, or high bushes. Nearby objects can block the flow of air to the thermometers and affect the amount of rain that collects in the rain gauge. Ideally the rain gauge and the instrument shelter should be placed four times as far from an object as that object is high. For example, if your site is surrounded by trees or buildings that are 10 meters tall, place your instruments at least 40 meters from these trees.
