As astronomical instruments become more sophisticated they rapidly reach the point where the scientific value is limited by the turbulence in the Earth's atmosphere distorting the light from distant galaxies, stars, planets and even our sun. In order to correct for these detrimental effects we must understand the dynamics of the atmosphere and to develop novel mitigation systems. In pristine, mountain top, observatories this is now common practise using dedicated turbulence profile instrumentation. However, at other observatories in less favourable locations or during the daytime, the atmospheric turbulence can be considerably stronger. Conventional turbulence monitoring instrumentation and correction systems do not work in these difficult conditions. The purpose of this programme is to develop the understanding and instrumentation in order to characterise the Earth's atmospheric turbulence in non-favourable conditions.

随着天文仪器变得越来越复杂，它们很快就会达到这样一个程度，即地球大气中的湍流扭曲了来自遥远星系、恒星、行星甚至我们的太阳的光线，从而限制了科学价值。为了纠正这些有害影响，我们必须了解大气的动态，并开发新的缓解系统。在原始的山顶天文台，这是现在使用专门的湍流剖面仪器的普遍做法。然而，在其他位置较差的观测站，或在白天，大气湍流可能会相当强烈。传统的湍流监测仪器和校正系统不能在这些困难的条件下工作。该方案的目的是发展对地球大气湍流的了解和仪器，以便描述地球在不利条件下的大气湍流。
