The amount of precipitation is determined using a rain gauge. It looks like a bucket protected by petals. The precipitation gauge is installed on a pillar about 2 m high. To determine the amount of precipitation, water from the precipitation gauge is poured into a measuring glass and the layer thickness in millimeters is determined. If the precipitation fell in solid form (snow, hail), then the bucket from the rain gauge is brought into a warm room, the snow melts there, and water is also poured into a measuring glass. The amount of precipitation is measured twice a day: at 7 am and at 19 pm. The amount of precipitation in a month is equal to the sum of precipitation in all days of the month. The amount of precipitation that fell for all months of the year is the annual amount of precipitation. The average long-term precipitation is also calculated.
