Measuring rainfall is a key aspect of meteorological monitoring, which is directly linked to our daily travel plans and has a significant impact on many areas such as irrigated agriculture, water resource management and transport. So how does the meteorological field measure rainfall?
Automatic rainfall monitoring relies on two main types of instruments: optical rain gauges and radar rain gauges.
1. Optical rain gauges measure precipitation through light sensing technology. It uses optical sensors to sense how much the light beam is blocked by the precipitating material, and then converts this information into a value for the amount of precipitation using a built-in algorithm.
2. A radar rain gauge, on the other hand, detects precipitation distribution by emitting radar waves and receiving their echoes. It estimates the amount of precipitation based on the reflected signals of the radar waves through a specific algorithm.
Both instruments have their own advantages. Optical rain gauges are suitable for measuring precipitation accurately over a small area, while radar rain gauges are more suitable for monitoring the distribution of precipitation over a large area.
Rain sensors are instruments that are designed to measure the amount of rainfall, capturing how much or how strong it is through specific sensing techniques. Such sensors play an important role in several key areas.
In meteorology, the data provided by rain sensors is essential for producing accurate weather forecasts and in-depth climate analyses. In agriculture, it assists farmers in pinpointing the best time to irrigate and the amount of water needed. In water management, rain sensors play an important role in monitoring water resources, flood prevention, and drought assessment.
A radar rain sensor is a sensor that utilizes the radar principle to measure rainfall. It utilizes radar technology to measure the microwave signals reflected back from rainfall, so as to obtain information such as the size, number and speed of raindrops, and then calculate the intensity and amount...
