ACES TIMING DATA

The ALTUS Cloud Electrification Study (ACES) was based at the Naval Air Facility Key West in Florida. During August or 2002, ACES researchers overflights of thunderstorms over the southwestern corner of Florida. For the first time in NASA research, an uninhabited aerial vehicle (UAV) named ALTUS was used to collect cloud electrification data. Carrying field mills, optical sensors, electric field sensors and other instruments, ALTUS allowed scientists to collect cloud electrification data for the first time from above the storm, from its birth through dissipation. This experiment allowed scientists to achieve the dual goals of gathering weather data safely and testing new aircraft technology. This dataset consists of timing data used for the experiment. When used it provides: syncclock_time = time found at the syncclock (VSI-SYnCCLOCK-32) in seconds from first file name, syncclock_m_time = time found at the syncclock (VSI-SYnCCLOCK-32) in Matlab dateform format, system_time = system time in seconds from first file name, system_m_time = system time in dateform format, gps_time = time found at the GPS unit in seconds from first file name, gps_m_time = time found at GPS unit in dateform, cmos_time = time found at the computer CMOS in seconds from first file name, cmos_m_time = time found at the computer CMOS in dateform.

ALTUS 云电化研究（ACES）以佛罗里达州基韦斯特海军航空基地为基地。在2002年8月期间，ACES 研究人员对佛罗里达州西南角的雷暴进行了空中巡查。在NASA研究史上，首次采用了名为ALTUS的无人飞行器（UAV）来收集云电化数据。ALTUS携带着场强计、光学传感器、电场传感器以及其他仪器，使得科学家们能够首次从风暴上方，自其生成直至消散的过程中收集云电化数据。该实验实现了收集气象数据的安全性与测试新型飞机技术的双重目标。本数据集包含用于实验的时序数据。当使用时，它提供以下信息：syncclock_time = 从第一个文件名中获取的同步时钟（VSI-SYnCCLOCK-32）的时间（以秒为单位），syncclock_m_time = 从同步时钟（VSI-SYnCCLOCK-32）中获取的时间（以Matlab日期格式），system_time = 从第一个文件名中获取的系统时间（以秒为单位），system_m_time = 以日期格式获取的系统时间，gps_time = 从第一个文件名中获取的GPS单元时间（以秒为单位），gps_m_time = 从GPS单元中获取的时间（以日期格式），cmos_time = 从第一个文件名中获取的计算机CMOS时间（以秒为单位），cmos_m_time = 从计算机CMOS中获取的时间（以日期格式）。
