ATM-9419638 VanZandt Abstract We propose to continue the operation and development of the Flatland Atmospheric Observatory (FAO), located in very flat terrain near Champaign-Urbana, Illinois, for three years. Instrumentation at FAO includes a five-beam 50 MHz wind-profiling radar, a five-beam 915 MHz wind-profiling radar with a radio- acoustic sounding system (RASS) to measure temperature profiles, a ground meteorological station, an array of 24 digital barographs centered on FAO, and a facility to launch radiosondes to measure temperature and humidity. All of the instruments except the radiosondes operate continuously through thee year. FAO will be use for atmospheric research principally in the following areas: (1) Studies of the mesoscale wind field, particularly gravity waves and momentum flux; and (2) Studies of the planetary boundary layer, particularly structure and entrainment, heat budget, and precipitaion classification. Considerable effort will be devoted to exploring the technology of wind-profiling radars; that is, their capabilities for observing microscale and mesoscale wind structures, as well as long term vertical velocities.

ATM-9419638范赞特摘要 我们建议继续运作和发展位于伊利诺伊州香槟-厄巴纳附近非常平坦的地形上的平地大气观测站（粮农组织），为期三年。 粮农组织的仪器设备包括一个五波束50兆赫风廓线雷达、一个五波束915兆赫风廓线雷达，配备无线电-声学探测系统以测量温度廓线、一个地面气象站、一个以粮农组织为中心的24个数字气压计阵列，以及一个发射无线电探空仪以测量温度和湿度的设施。除无线电探空仪外，所有的仪器都连续运行三年。 粮农组织将主要用于下列领域大气研究：（1）研究中尺度风场，特别是重力波和动量通量;（2）研究行星边界层，特别是结构和卷吸、热量收支和降水分类。 将作出相当大的努力，探索风廓线雷达技术，即其观测微尺度和中尺度风结构以及长期垂直速度的能力。
