Surrogate models that emulate the full forward physical RTM can speed up the simulation, reducing computational and timing costs and allowing the use of more advanced physics for trace gas retrievals. In this study, we present the development of surrogate models for two RTMs: the RemoTeC algorithm using the LINTRAN RTM and the SCIATRAN RTM. We estimate the intrinsic dimensionality of the input and output spaces and embed them in lower dimensional subspaces to facilitate the learning task. Two methods are tested for dimensionality reduction, autoencoders and principle component analysis (PCA), with PCA consistently outperforming autoencoders. 2023-03-31T02:08:04Z 2023-03-31T02:08:04Z 2023 Book https://link.springer.com/article/10.1007/s10994-022-06155-2 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7363 en application/pdf Springer |
