What is an atmometer?

An atmometer is a scientific instrument used to measure the rate of evaporation from a surface, often in relation to the surrounding atmosphere. It is commonly used in studies of weather, climate, agriculture, and environmental science to monitor and understand water loss from soil and plants. The data collected can help determine irrigation needs, assess water balance in ecosystems, and study the relationship between evaporation and other climatic variables such as temperature, humidity, and wind speed. Different types of atmometers exist, such as porous cup atmometers and wet-plate atmometers, each with their own method of measuring evaporation rates.
