Earth outward radiation energy calculation method based on moon-based platform

Abstract

The invention discloses an earth outward radiation energy calculation method based on a moon-based platform. A DE430 ephemeris file, earth pointing parameters and a geometric model between the sun, the earth and the moon are utilized; firstly, the visibility of the surface of the moon and the top of the whole atmosphere of the earth is calculated, then a method for calculating the outward radiation energy of the moon-based platform to the earth is established by utilizing a thermal radiation transmission law and an energy conservation law, and the radiation energy is composed of long-wave radiation energy emitted by the earth and solar short-wave radiation energy reflected by the earth. From the radiation transmission law and the energy conservation law, the earth outward radiation energyreceived by the unit earth visible area at any moon surface earth visible position at any moment can be calculated; the calculated energy value can provide technical support for the system parameter design of the earth outward radiation energy detector based on the moon-based platform, and can provide a basis for the accurate calculation of the lunar surface temperature, the placement position ofthe lunar surface detector and the thermal control design of the lunar surface detector.

Description

technical field [0001] The invention belongs to the technical field of observation of the earth's outward radiation energy by a moon-based detection platform, and in particular relates to a method for calculating the earth's outward radiation energy based on a moon-based platform. Background technique [0002] In recent decades, global climate change has become an extremely urgent social and scientific issue. The main factor of global climate change is the energy balance of the earth's climate system. Taking the top of the atmosphere as the reference surface for research can determine the dynamic changes of the earth's climate system. It is driven by two parts: incoming solar radiation and outgoing earth radiation. There are two forms of radiant energy emitted by the earth: reflected solar short-wave (SW) radiation and long-wave infrared (LW) radiation emitted by the earth itself, and the precise measurement of these two quantities depends largely on space measurements tech...

Problems solved by technology

Of course, lunar probes will also face many challenges, such as the huge temperature difference between day and night, high-energy particles from outer space, suspended moon dust, and the highly vacuum space environment, etc.
