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.

Query step

Step 1: Select the geographical location of the platform. You can choose single point data or regional average data anywhere in the world.

Step 2: Confirm the data source. What digital sources, European medium-range weather centers and selections can be used for historical data? The forecast data can be selected from the German Meteorological Bureau.

Step 3: Enter the start and end time of the download you want to query. You can choose 40 years of history and 7 days in the future.

Step 4: Select the meteorological data to be downloaded, export the hourly data in csv format, save the data visualization picture, or select the API interface as needed.

Step 5: If you need to query more data, you can search for attributes in more attributes.
