Modelling synthetic atmospheric turbulence profiles with temporal variation using Gaussian mixture model (2018)
Journal Article
Jia, P., Osborn, J., Kong, L., Laidlaw, D., Li, C., Farley, O., & Xue, G. (2018). Modelling synthetic atmospheric turbulence profiles with temporal variation using Gaussian mixture model. Monthly Notices of the Royal Astronomical Society, 480(2), 2466-2474. https://doi.org/10.1093/mnras/sty1951

The atmospheric turbulence profile plays a very important role for performance evaluation of wide-field adaptive optic systems. Since the atmospheric turbulence is evolving, the turbulence profile will change with time. To better model the temporal v...
