Researchers have developed SIMBA, a novel bidirectional framework for modeling hyperspectral infrared radiances from the FY-4A GIIRS instrument. This framework uniquely integrates atmospheric profile retrieval and radiance reconstruction, employing a cycle-consistency constraint to enhance their coupling. By utilizing a bidirectional Mamba state-space module, SIMBA effectively captures long-range dependencies crucial for numerical weather prediction applications. Experiments using collocated FY-4A GIIRS observations and ERA5 reanalysis data demonstrate SIMBA's superior performance over existing deep learning baselines in both retrieval and reconstruction tasks.
