1. IntroductionTraditionally, computational fluid dynamics (CFD) simulation and wind tunnel experiments have been the main methods for obtaining the external flow field of obstacles. However, these methods are associated with substantial costs and time requirements. With the development of the computer science field, deep learning has seen rapid growth in applications such as speech recognition [1], image recognition [2], and natural language processing [3] in recent years.

1 IntroductionAtmospheric methane (CH4) is an important greenhouse gas (Fletcher and Schaefer, 2019) and precursor of tropospheric ozone (Staniaszek et al., 2022). The CH4 concentrations have been steadily increasing since the preindustrial period (Aben et al., 2017). Recent observations showed a CH4 rise of 267 ppb (16.2%) from 1984 to 2022 though with large interannual variations (Lan et al., 2022).
