The ideal location for a rain gauge is an open area away from obstructions that could affect rainfall collection. Here's a breakdown:
Key Considerations for Rain Gauge Placement
Distance from Obstacles
The primary concern is to minimize interference from trees, buildings, or other objects. These obstructions can block rainfall, leading to inaccurate measurements.
- Rule of Thumb: If you have a tall object like a tree, the general guideline is to place the rain gauge at least twice the height of the object away from it, downwind.
- Example: If a tree is 40 feet tall, the rain gauge should be at least 80 feet away from the tree (downwind) (Rain Gauge).
Practical Advice
- Open Area: Choose the most open area available on your property.
- Downwind Placement: Consider the prevailing wind direction in your area and place the gauge downwind of any potential obstructions.
- Level Surface: Ensure the rain gauge is placed on a level surface to prevent inaccurate readings due to tilting.
- Accessibility: Place the rain gauge in a location that is easy to access for regular readings and maintenance (emptying).
- Avoid Splashing: Avoid placing the rain gauge where water could splash into it from nearby surfaces.
- Secure Mounting: Secure the rain gauge to prevent it from being knocked over by wind or animals.
