AsosDaIyInfoService
A service that searches for daily weather data observed with synoptic meteorological observation equipment. Surface weather observation (ASOS) is an observation of meteorological elements and phenomena near the ground and on the ground, such as temperature, precipitation, air pressure, humidity, solar radiation, and solar irradiance. Production cycle: Hours, days Retention period: April 1904 (varies by location) ~ (Reference) Difference between ASOS and AWS - (ASOS), synoptic meteorological observation, mainly installed in major cities, operated by the Korea Meteorological Administration, all elements of synoptic meteorology (regular observation), forecasts, climate statistics, and international sharing - (AWS) Operates a dense regional network in mountainous areas and islands, mixed operation by the Korea Meteorological Administration and local governments, some meteorological elements (precipitation, temperature, etc.), local disaster monitoring, and auxiliary observation.
