Meteorological data index

Temperature: refers to the temperature in the louver at a height of about 1.5-2 meters.

Humidity: refers to the air humidity of about 1.25 ~ 2m above the plateau.

Air pressure: refers to the air pressure value in this area.

Precipitation: refers to the depth at which liquid or solid (after melting) water falls from the sky to the ground and accumulates on the horizontal plane without evaporation, infiltration and loss.

Meridional wind: refers to the meridional component of the upwind at a height of about 10m (the southerly wind is positive).

Zonal wind: refers to the zonal component of the upwind in the highlands around 10m (the westerly wind is positive).

Surface wind speed: refers to the wind speed about10m above the ground.

Wind direction: refers to the direction of the wind, with due north being 0 and clockwise being positive.

Surface horizontal radiation: the total amount of solar radiation injected into the surface unit horizontal plane.

Direct radiation: refers to the direct radiation of the sun from the round surface of the sun and the area closest to the sun (the round surface of the sun, with a center of 5 degrees).

Scattered radiation: refers to the radiant energy when sunlight meets clouds, gas molecules, dust, etc. In the process of reaching the ground through the atmosphere, it reaches the surface of the earth in the form of diffusion.
