John Dalton (rainfall measurement)

John Dalton was a scientist who developed a method to measure rainfall accurately. His approach involved collecting rainwater in a graduated container, known as a rain gauge, which has marked measurements to determine the amount of precipitation in a specific area. This simple device allows for precise recording of rainfall amounts over a period, aiding meteorologists and climatologists in studying weather patterns and climate. Dalton's work helped standardize rainfall measurement, making it essential for weather forecasting and understanding water resources.
