Tethered Atmospheric Observation System (TAOS) Data. Version 1.0

The Tethered Atmospheric Observing System (TAOS) used during the IHOP project was located one mile east of the Homestead site, on the south side of the road (Lat 36 deg 33.500 min N, Lon 100 deg 36.371 min W, Alt 850m). The tethered system is comprised of up to eight NCAR designed and built sensor platforms using the Vaisala RS-90 P, T and RH sensor package for these measurements. Wind speed comes from an R.M. Young propellor using an optical chopper. Wind direction comes from a Honeywell magnetometer which provides pitch and roll information in addition to direction. The sensor packages are tethered to a large balloon, and are spaced apart at various altitudes along a line attached to the balloon. Each transmits one second resolution data simultaneously over a period of time. The IHOP TAOS datasets were collected on June 12, 14 and 21 of 2002.

IHOP项目中使用的系留大气观测系统（Tethered Atmospheric Observing System，简称TAOS）布设在美国霍姆斯特德站点以东1英里处的道路南侧，地理坐标为北纬36°33.500′，西经100°36.371′，海拔850米。该系留系统最多可搭载8个由美国国家大气研究中心（NCAR）设计制造的传感器平台，此类平台采用维萨拉（Vaisala）RS-90 P、T及RH传感器组件开展观测。风速数据由搭载光学斩波器的R.M. Young螺旋桨式传感器测得；风向数据则来自霍尼韦尔（Honeywell）磁强计，该设备除可提供风向信息外，还能同步输出俯仰与横滚姿态数据。各传感器组件均系留于大型气球下方，沿连接气球的缆绳在不同海拔高度依次布设，且均可在观测时段内同步传输分辨率为1秒的观测数据。本次IHOP项目的TAOS数据集采集于2002年6月12日、14日及21日。
