🔭 Mountaintop Observatory Site Lab: Airmass, Extinction, Fried Parameter and Seeing - 2D Atmosphere Cross-Section

Atmosphere cross-section of an observatory site: Kasten-Young airmass, Rayleigh and aerosol extinction above an inversion, Hufnagel-Valley turbulence, Fried parameter, seeing, isoplanatic angle and a live speckle point-spread function from an FFT phase screen. Same engine as the 3D page.
