Application of Neural Networks to Estimation and Prediction of Seeing at the Large Solar Telescope Site

Abstract: Optical turbulence limits the angular resolution of ground-based astronomical telescopes. The key parameter of optical turbulence is seeing. In this study, seasonal variations of seeing estimated from differential image motion monitor measurements at the Large Solar Telescope site are discussed. The Large Solar Telescope will be located at an elevation of 2000 m above sea level ( 51 ° 37 … Show more

“…Analysis of the neural networks obtained shows that individual bright connections between neurons are substituted for most configurations with nearly equal-weight coefficients. Unlike the Sayan Solar Observatory, the deep neural networks obtained for the Maidanak Astronomical Observatory do not contain pronounced connections between the seeing parameter and atmospheric vorticities [34]. Moreover, the use of atmospheric vorticities in the simulation even slightly reduces the Pearson correlation coefficient between the model and measured seeing values.…”

“…Lanzaco et al integrated an artificial neural network and SVM to obtain an improved AOD map for South America [26]. The deep learning approach performs better in solving nonlinear problems of atmospheric characteristics [27][28][29]. A deep learning model with multiple hidden layers can simulate highly varying functions defining nonlinear structures [30,31], which is suitable for the determination of the nonlinear relationships between satellite measurements and the AOD.…”
