GB/T 12763.3-2007

This standard specifies the methods, instruments, and data processing requirements for conducting marine meteorological observations, including measurements of wind, air temperature, humidity, atmospheric pressure, and visibility at sea. It is applied in Chinese oceanographic surveys, marine scientific research, and operational meteorology to ensure consistent and reliable meteorological data collection from ships, buoys, and coastal stations. The standard is critical for weather forecasting, climate studies, and marine safety assessments in China's coastal and offshore waters.
