1992年11月，通过日本和印度尼西亚之间的合作，在印度尼西亚雅加达附近建立了一个雷达观测站，我们在那里安装了流星风雷达和边界层雷达。用MWR分别以1小时和4公里的时间和高度分辨率测定了75-100公里处的水平风速和温度波动。BLR提供了行星边界层（0.3-5公里）每分钟的三个风速分量，高度分辨率为100米。此外，通过结合声学发射器，还通过RASS（无线电声学探测系统）技术与BLR一起获得了温度分布。自1992年11月以来，雷达观测已持续了两年多。1992年11月至1993年4月期间，在万隆的LAPAN用无线电探空仪测量了水平风速、温度和湿度的分布，高度分辨率为150米，最高可达35公里，每天四次。此外，1993年10月以后，无线电探空仪每天例行探测一次。初步的资料分析显示了印度尼西亚上空赤道大气动力学的一些新方面，如热带行星边界层的结构和中层大气中大气波的行为。本文介绍了TOGA/COARE活动期间的雷达设备、观测现状和赤道大气动力学的基本特征。
Through collaboration between Japan and Indonesia, a radar observatory was established near Jakarta, Indonesia in November 1992, where we installed a meteor wind radar (MWR) and a boundary layer radar (BLR). Horizontal wind velocity and temperature fluctuations at 75-100 km were determined with the MWR with time and height resolution of 1 hour and 4 km, respectively. The BLR provided three components of wind velocity every minute in the planetary boundary layer (0.3-5 km) with a height resolution of 100 m. In addition, by combining an acoustic transmitter, temperature profiles were also obtained with the BLR by means of the RASS (radio acoustic sounding system) technique. Observations with the radars have been continued over 2 years since November 1992. Profiles of horizontal wind velocity, temperature and humidity were measured with radiosondes up to 35 km, with a height resolution of 150 m, four times a day during November 1992-April 1993 at LAPAN in Bandung. Further, radiosonde sounding has been routinely continued once a day after October 1993. Preliminary data analysis showed some new aspects of the equatorial atmosphere dynamics over Indonesia, such as the structure of the tropical planetary boundary layer and the behavior of atmospheric waves in the middle atmosphere. We report in this paper a description of the radar equipment, the current status of observations and the fundamental characteristics of equatorial atmosphere dynamics during the TOGA/COARE campaign.
