光学turbulence预报:迈向地基天文学的新时代

Optical turbulence forecast: toward a new era of ground-based astronomy

E. Masciadri

摘要:

用非静力大气模式在中尺度上模拟天文学应用中的光学湍流(OT),就测量而言,具有一些优点。地基天文学的未来取决于ELT的潜力和可行性。我们在了解、控制和“管理”湍流对新一代望远镜和设施的影响方面的能力,是确保它们在空间天文学方面具有竞争力的决定性因素。在过去,已经进行了几项研究,证明了模拟天文台上空真实的Cn 2剖面的可行性。欧洲共同体(FP6计划)最近决定资助一个项目,旨在从一方面证明OT预报的可行性和中尺度模式从光学湍流角度区分天文站点的能力,另一方面促进这一处于天体物理学和气象学之间的学科的发展。在这篇文章中,我将介绍这个项目的科学和技术目标,与这样一个项目的成功有关的地基天文学的挑战,以及为优化结果而联合的国际协同作用。

英文摘要:

The simulation of the optical turbulence (OT) for astronomical applications obtained with non-hydrostatic atmospherical models at meso-scale presents, with respect to measurements, some advantages. The future of the ground-based astronomy relies upon the potentialities and feasibility of the ELTs. Our ability in knowing, controlling and 'managing' the effects of the turbulence on such a new generation telescopes and facilities are determinant to assure their competitiveness with respect to the space astronomy. In the past several studies have been carried out proving the feasibility of the simulation of realistic Cn2 profiles above astronomical sites. The European Community (FP6 Program) decided recently to fund a Project aiming, from one side, to prove the feasibility of the OT forecasts and the ability of meso-scale models in discriminating astronomical sites from optical turbulence point of view and, from the other side, to boost the development of this discipline at the borderline between the astrophysics and the meteorology. In this contribution I will present the scientific and technological goals of this project, the challenges for the ground-based astronomy that are related to the success of such a project and the international synergies that have been joint to optimize the results.
