The NSF Major Research Instrumentation Program (MRI) is designed to improve the condition of scientific and engineering equipment and facilities for research and training in the NationÆs academic institutions. For twenty-five years the University of Washington (UW) has maintained and utilized a sophisticated airborne facility for atmospheric research and for the training of students. This facility has been used for a wide range of important (often unique) investigations, including studies of the sources and sinks of atmospheric trace gases and particles (e.g., volcanoes, biomass burning and various anthropogenic sources), the role of clouds in weather and climate (e.g.. clouds as chemical processors; the microstructure of clouds; the optical and radiative properties of clouds and their effects on climate), and the mesoscale structures of large storm systems (e.g., the organization of clouds and precipitation in mid-latitude cyclones).In 1997 the UW acquired a new platform for such studies (a twin-engine turboprop Convair 580). which has significantly greater performance capabilities than the previous aircraft used by the UW. This MRI award provides for the purchase of a new generation of research instruments to be carried on the Convair 580. These include instruments for measuring several trace gases of key importance in atmospheric chemistry, several new instruments for measuring the size distributions and concentrations of airborne particles, measurements of the size spectra of precipitation particles, measurement of three-dimensional air motions, and a new data acquisition system for the aircraft.These instruments will permit investigations of a variety of outstanding issues related to the earth's changing atmosphere, weather and climate and will aid the formation of new research partnerships. The new integrated research facility will be used also for the enhanced training of undergraduate and graduate students in airborne atmospheric research.

美国国家科学基金会重大研究仪器计划（MRI）旨在改善NationÆs学术机构的科学和工程设备和设施的研究和培训条件。25年来，华盛顿大学（UW）一直维护和利用先进的机载设施进行大气研究和学生培训。该设施已被用于广泛的重要（通常是独特的）调查，包括研究大气微量气体和颗粒的来源和汇（例如火山、生物质燃烧和各种人为来源）、云在天气和气候中的作用(例如……云是化学处理机；云的微观结构；云的光学和辐射特性及其对气候的影响)，以及大型风暴系统的中尺度结构（例如，中纬度气旋中的云和降水的组织）。1997年，华盛顿大学获得了一个用于此类研究的新平台（双引擎涡轮螺旋桨飞机Convair 580）。它比美国以前使用的飞机具有更大的性能。这项核磁共振奖为购买新一代研究仪器提供了资金，这些仪器将搭载在Convair 580上。这些仪器包括用于测量几种在大气化学中至关重要的微量气体的仪器，用于测量空气中颗粒的大小分布和浓度的几种新仪器，用于测量降水颗粒的大小光谱，测量三维空气运动，以及用于飞机的新数据采集系统。这些仪器将允许研究与地球不断变化的大气、天气和气候有关的各种悬而未决的问题，并将有助于形成新的研究伙伴关系。新的综合研究设施还将用于加强对机载大气研究方面的本科生和研究生的培训。
