The Trans Pacific Profiler Network: Investigating Tropical Processes

自1988年以来，由于得到了一系列赠款，科罗拉多大学的国际遥感研究中心得以与美国国家海洋和大气管理局高空大气层实验室合作，在横跨赤道太平洋的四个地点建造、操作和维护甚高频风廓线雷达：印度尼西亚的比亚克、密克罗尼西亚的波恩佩、基里巴斯的圣诞岛和秘鲁的皮乌拉。 圣诞岛剖面仪的观测结果现已例行纳入业务预报模式。 正在利用该网络提供的数据开展的研究活动包括：（1）记录热带太平洋上空风的季节性和年际变化;（2）调查大气开尔文波、Rossby波和重力波的结构;（3）测量剖面仪站点的垂直结构和降雨量;（4）获取验证大气模型的数据。 该网络满足了对热带太平洋风和降水数据的研究和业务需求-这是一个对全球气候很重要的区域，但其他数据来源很少。

A continuing series of grants since 1988 has made it possible for CIRES of the University of Colorado, in collaboration with the NOAA Aeronomy Laboratory, to construct, operate, and maintain VHF wind-profiling radars at four sites stretching across the equatorial Pacific: Biak, Indonesia; Pohnpei, Micronesia; Christmas Island, Kiribati; and Piura, Peru. Observations from the profiler at Christmas Island are now assimilated into operational forecast models on a routine basis. Ongoing research activities based on data from the network include: (1) documentation of seasonal and interannual variability of winds over the Tropical Pacific; (2) investigation of the structure of atmospheric Kelvin waves, Rossby waves, and gravity waves; (3) measurement of the vertical structure and amount of rainfall at the profiler sites; (4) obtaining data for the validation of atmospheric models. The network fills both research and operational needs for data on winds and precipitation in the Tropical Pacific - a region important for the global climate, but where other sources of data are scarce.
