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.

自1988年以来，一系列持续的拨款使科罗拉多大学的CIRES得以与NOAA航空实验室合作，在横跨赤道太平洋的四个地点建造、运行和维护甚高频风廓线雷达：印度尼西亚的Biak；颂、密克罗尼西亚;圣诞岛，基里巴斯；秘鲁的皮乌拉。圣诞岛剖面仪的观测资料现在已被纳入常规的业务预报模式。正在进行的基于该网络数据的研究活动包括：(1)记录热带太平洋上空风的季节和年际变化；(2)大气开尔文波、罗斯比波和重力波的结构研究；(3)测量廓线站点的垂直结构和降雨量；(4)获取大气模式验证数据。该网络满足了对热带太平洋地区风和降水数据的研究和业务需求。热带太平洋地区对全球气候很重要，但其他数据来源很少。
