Ground-based weather stations

Definition

Ground-based weather stations are facilities equipped with instruments to observe and record meteorological data at the Earth's surface. These stations provide essential information about temperature, humidity, wind speed, and atmospheric pressure, which is vital for understanding weather patterns and climate conditions. The data collected by these stations undergoes various quality control measures and analysis techniques to ensure accuracy and reliability.
