👉 Solarimeter is a device used in meteorology and astronomy to measure the temperature of the Earth's surface. It consists of a small metal plate or glass tube with a thin layer of mercury (or other liquid) on its outer surface. The mercury acts as a thermometer, indicating the average temperature at any given location on the Earth's surface. The solarimeter is used in weather forecasting and climate modeling to predict weather patterns and identify areas that may be vulnerable to extreme temperatures.
