Hyperspectral Infrared Atmospheric Vertical Sounder-II Atmospheric Product Inversion System Design
With the intensification of global climate change, the monitoring of atmospheric trace gases has received increasing attention. The column concentrations and profiles distributions of trace gases become the data basis for atmospheric environmental monitoring and global climate change research. The Hyperspectral Infrared Atmospheric Vertical Sounder II (HIRAS-II) on board the Fengyun-3E and Fengyun-3F satellites provides high spectral resolution infrared radiometric observations of the Earth-gas system, which can be used to invert high-precision atmospheric compositional profiles and column concentrations. In this study, we have developed an operational inversion system based on HIRAS-II. This system incorporates a modular design and parallel computing framework, integrating a global reference atmospheric profile database and surface emissivity database. Leveraging the optimal estimation methods and the RFM forward model, this system inverts the CH4, O3 profiles and column concentrations products as well as CO2 column concentrations products. The inversion system was tested and the accuracy of the 12 products obtained by the inversion system is verified. The results show that the inversion system operated stably and the products had high accuracy. The inversion system can provide algorithmic and technical support for atmospheric environment monitoring in China and global climate change research.
