Abstract

Abstract:

Space-borne trace gas different optical absorption spectrometer is one of the important payloads, which is mounted on the sun-synchronous orbit. It is used to obtain the hyper-spectral remote sensing products in ultraviolet to visible band. It also can be used to monitor the global air quality change quantitatively and the global distribution and transport process of pollutants. In order to satisfy the reading and writing function of a large amount of real-time remote sensing data, the fast and effective searching and reading requirements of load data are realized. HDF5 data format is used to store remote sensing data. To test the validity of the data, based on the remote sensing data of level 0 obtained from laboratory, through the dark background subtraction, gain correction, spectral calibration and radiometric calibration and other processing, the remote sensing data of level 1 is obtained, and successfully written to the HDF5 file. This process will provide data products for atmospheric trace gases data concentration inversion when this payload is in orbit.

Key words: space-borne trace gas different optical absorption spectrometer, HDF5, remote sensing data of 1 level
