Description
Technical Field
The invention relates to the technical field of radiometry, in particular to a solar total irradiance calibration device which can be traced to SI.
Background
The sun is the source of energy for the earth's climate system, driving almost every dynamic process in the earth's system. The Total Solar Irradiance (TSI) is one of several key parameters of the optical field that are provided by the international society in consideration of the need for the study of climate change, and only if the important parameters affecting the climate change are observed for a long time on the basis of proper uncertainty to establish key data, the reason for the change and the result brought therewith can be determined in the whole study of climate change, and the future climate development trend can be reliably predicted. The TSI measurement based on the satellite platform is taken as a key development plan by multiple countries in the world, and various radiometers successively carry different satellite platforms, such as ERB in the United states, VIRGO in Switzerland, ACRIM in Belgium, Chinese Fengyun satellite and the like. 40 years of spatial solar total irradiance data was accumulated, with a well-accepted solar constant of 1361W/m 2.
The adoption of a radiometric calibration device to correct the radiometric calibration of the space optical remote sensing instrument is an important link in the development process. The method is limited by a calibration light source and the like, and external field comparison calibration is mainly adopted for radiometric calibration before emission of the solar absolute radiometer. In order to unify the world radiometric scale, the world radiometer at the end of the seventies of the last century adopts nine types of fifteen absolute radiometers as a World Standard Group (WSG) in Darwos of Switzerland, the weighted average measurement result is used as a World Radiometric Reference (WRR), an international insolation intensity comparison (IPC) is held every five years, the solar absolute radiometers of all countries in the world synchronously observe the solar radiation of the foundation in an external field and the WSG, the radiometric scale is traced to the WRR reference, and the calibration precision can reach 0.3%. A wind cloud three-number solar radiation monitor (SIM/FY-3) is the only solar total irradiance monitoring instrument based on the space in China. Ground-based solar absolute radiometers (SIARs) were attended to IPC experiments from 2000 to switzerland, and radiation scales were corrected. Through the outfield alignment, SIARs passed the WRR reference to SIM/FY-3. Based on WRR reference, the on-orbit data consistency of the SIM/FY-3 and the international synchronization instrument is 0.3 percent, and the requirement of climate change research is difficult to meet.
The prior calibration device has the following technical problems: firstly, the solar light source adopted by the external field calibration device reduces the stability of the light source due to the change of atmospheric conditions. And secondly, the external field calibration device operates in a normal temperature and normal pressure environment, and has difference with a vacuum environment in actual on-orbit operation, so that the introduced vacuum and normal pressure correction coefficient is difficult to correct, and the system error is increased. And finally, the uncertainty of measurement of the WRR reference source is 0.2%, and the source cannot be traced to the SI. In conclusion, the calibration precision of the external field calibration device is difficult to further improve, and the requirement of the high-precision solar radiation instrument monitor on the calibration precision cannot be met.
