Environmental requirements of meteorological observation stations

The ground meteorological observation field must meet the observation technical requirements.

(1) The ground meteorological observation station is the main place to obtain ground meteorological data, and the site should be selected in a place that can better reflect the characteristics of local meteorological elements in a large range to avoid the influence of local topography. The observation site must be empty and flat around, and avoid being built on steep slopes, depressions or near railways, highways, mines, chimneys and tall buildings. Avoid local places with serious air pollution such as fog and smoke.

The shadow of obstacles around the ground meteorological observation field should not be projected on the light receiving surface of the sunshine and radiation observation instrument, and there is no object with strong sunlight reflection nearby.

(2) In cities or industrial and mining areas, the observation field should be selected on the windward side of the windward direction in cities or industrial and mining areas.

(three) the surrounding environment of the ground meteorological observation site shall meet the requirements of the Meteorological Law of People's Republic of China (PRC) and the laws, regulations and normative documents on meteorological observation environmental protection.

(4) The environment of ground meteorological observation sites must be protected according to law.

(5) After the observation environment around the ground meteorological observation field changes, detailed records should be made. When the obstacles around the newly-built or relocated observation field change obviously, the azimuth and height angles of the surrounding obstacles should be determined, and the obstacle occlusion map of the horizon should be drawn.

(6) The environmental conditions of unattended weather stations and mobile weather stations can be mastered by themselves according to the purpose of setting up the stations.
