Abstract : With increasing telescope sizes, adaptive optics (AO) systems are essential to counteract the effects of atmospheric turbulence. Single Conjugate AO systems provide correction only over a limited field-of-view (10 -15 arcsec). Multi Conjugate Adaptive Optics (MCAO) systems overcome this by correcting for the turbulence in different layers of the atmosphere and increasing the corrected field-of-view to about 1-2 arcmin. A MCAO system will be required to achieve high contrast images over the full 3 arc-minutes field of view of the proposed National Large Solar Telescope (NLST). The development of a MCAO system requires detailed understanding of the distribution of the strength of the atmospheric turbulence over the atmosphere. We are initiating a project to study and understand the turbulence distribution over Kodaikanal and Merak. We start with a Python and MATLAB based simulations to understand the intricacies involved in such an endeavour.
