The Advanced Ceramics Research (ACR) company will build and provide field support for six (three flying and three backups) automated unmanned aerial vehicles (AUAVs) for the Maldives AUAV Campaign (MAC), scheduled for February 15 - March 31 2006. See also NSF grant, Ramanathan, UCSD, SIO, ATM 0542531.One of the fundamental challenges of observing how aerosols modulate cloud microphysics and cloud albedo is the need to observe the same cloud element simultaneously from below, above, and inside the cloud; i.e., to measure how much aerosol is being transported to the cloud from below and from above; to measure how the cloud drop number density as a function of drop radius is changing in response to the injection of aerosols; and, finally, to observe how the cloud albedo, in-cloud solar absorption, and the transmission of solar radiation through the cloud to the cloud base is responding to the change in cloud microphysical properties. Such a synchronized view of clouds has not been accomplished thus far. The particular emphasis of MAC is to demonstrate that lightweight AUAVs can fill an important and vital gap in our measurement capability by simultaneously sampling cloudy layers from all sides. The fundamental science objective of MAC is to provide new insights into how aerosols and clouds regulate the planetary albedo, with particular emphasis on how anthropogenic aerosols are modifying the albedo of cloudy skies (the so-called "indirect effect"). MAC also will be able to estimate solar absorption by clouds and to measure the dependence of that absorption on the amount of absorbing aerosols. MAC will provide direct measurements of cloud and aerosol microphysical properties and radiation fluxes by using coordinated flights of three AUAVs. Broader impacts. If successful, MAC will demonstrate that AUAVs are a relatively inexpensive, reliable instrument platform for observing synchronously, fast interactive processes, e.g., cloud and aerosol microphysics and feedbacks, in multi-dimensional space. MAC will provide climate scientists with a valuable data set for studying what is considered to be a major area of uncertainty in climate change research and projections. A student will be trained in field campaign operations and research. NOAA and NASA are co-supporting MAC, which is a project coordinated through the U.S. Climate Change Science Program.

先进陶瓷研究公司（ACR）将为定于2006年2月15日至3月31日进行的马尔代夫无人驾驶飞行器运动（MAC）建造6架（3架飞行和3架备份）无人驾驶飞行器并提供现场支持。另见NSF grant，Ramanathan，UCSD，SIO，ATM 0542531。观察气溶胶如何调节云微物理和云微物理的基本挑战之一是需要同时从云的下面、上面和内部观察相同的云元素;即，测量有多少气溶胶从下面和上面被输送到云中;测量云滴数密度作为云滴半径的函数是如何响应气溶胶的注入而变化的;最后，观察云的散射、云中太阳吸收以及太阳辐射通过云到云底的传输是如何响应云微物理特性的变化的。这样的云的同步视图到目前为止还没有完成。MAC特别强调的是，通过从各个方面同时对云层进行采样，轻型AUAV可以填补我们测量能力中的一个重要和至关重要的空白。MAC的基本科学目标是提供有关气溶胶和云如何调节行星云的新见解，特别强调人为气溶胶如何改变多云天空的云（所谓的“间接效应”）。MAC还将能够估计云层对太阳的吸收，并测量吸收对吸收气溶胶数量的依赖性。气象学中心将利用三架无人驾驶飞行器的协调飞行，直接测量云和气溶胶的微物理特性和辐射通量。更广泛的影响。如果成功，MAC将证明AUAV是一种相对便宜、可靠的仪器平台，用于同步观察快速交互过程，例如，云和气溶胶微物理学和反馈，在多维空间。MAC将为气候科学家提供宝贵的数据集，用于研究气候变化研究和预测中被认为是主要不确定领域的问题。一名学生将接受实地活动和研究方面的培训。NOAA和NASA正在共同支持MAC，这是一个通过美国气候变化科学计划协调的项目。
