The application discloses a method and a device for determining the earth's radiation balance based on meteorological satellite observation. Among them, the method includes: obtaining the first-level data of the earth radiation detector and the solar irradiance monitor, wherein the first-level data includes the observation value of the radiation-calibrated earth-atmosphere system reflected short-wave radiation and full-band radiation of the geographic positioning information ;According to the first-level data, determine the upward radiation flux of the top of the atmosphere, where the upward radiation flux of the top of the atmosphere is used to indicate the radiant energy passing through the upward spectrum integration of the top of the atmosphere per unit area and time; the sun observed by the solar irradiance monitor The irradiance product, together with the geometric angle of the sun, determines the top-of-atmosphere solar radiation flux, where the top-of-atmosphere solar radiation flux is used to indicate the spectrally integrated solar radiation energy incident on the Earth per unit area and unit time; and According to the top-up radiation flux of the atmosphere and the top-down solar radiation flux, the Earth's radiation budget is determined.

Description

technical field [0001] This application relates to the field of determining the earth's radiation budget, in particular to a method and device for determining the earth's radiation budget based on meteorological satellite observations. Background technique [0002] The Earth's radiation balance refers to the balance between the earth-atmosphere system absorbing incident solar radiation and reflecting, scattering, and emitting thermal radiation. The Earth's radiation balance consists of three components: absorbed solar radiation, reflected solar radiation, and emitted Earth radiation. Satellites are the only source that can conduct global observations of the radiation flux at the top of the atmosphere. In order to quantitatively calculate the Earth’s radiation budget, the inversion algorithm needs to convert satellite observations into radiation flux at the top of the atmosphere, so as to combine satellite observation data with scientific Use products to establish connection...
