1mm rain over two hours is barely a mist. It means rain caught in a measuring device will pool up to a height of 1mm. In 5 minutes for 1mm to fall things will get wet. Generally the sidewalks or road may get wet and in a dry climate be dry in half an hours or less.

Who invented rain gauge?

How does rain fall?

Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. ... Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.

Where is the best place to put a rain gauge?

Location! Keep your rain gauge in open areas as far away from obstacles as possible, whether trees, houses, or fences. Having your gauge level is another great way to keep the readings accurate. This will help rain from splashing out and to help with winds blowing.
