摘要/Abstract

摘要：

星载大气痕量气体差分吸收光谱仪搭载于太阳同步轨道卫星，用于获取紫外至可见波段的高光谱遥感数据，可定量监测全球痕量气体分布、变化及输运过程。为满足大量实时遥感数据的读写功能，并实现载荷数据的快速有效查找与读取要求，选择HDF5数据格式存储大气痕量气体差分吸收光谱仪获得的遥感数据。为测试数据的有效性，基于载荷在实验室获取的0级测试数据，通过暗背景扣除、增益修正、光谱定标与辐射定标等处理，获得1级遥感数据，并将其成功写入HDF5文件中，从而为载荷入轨后的处理提供数据支持。

关键词: 星载大气痕量气体差分吸收光谱仪, HDF5, 1级遥感数据

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
