摘要
地气间热通量是近年来生态环境研究的热点。介绍了利用大口径闪烁仪测量显热通量和径向风速的软件.为满足大口径闪烁仪在测量显热通量和横向风速的数据采集与处理的需要,采用PCI-8340数据采集卡,在Windows平台上用VC++6.0编程开发了对大口径闪烁仪的数据进行实时采集、处理与显示的软件,方便实验人员及时准确得到实验结果.通过软件数据的有效检测,可以完成无人值守的自动化工作.
Sensible and latent heat fluxes exchange between surface and atmosphere is a hot topic in ecoenvironmental research recent years. A software using large aperture scintillometer （LAS） to measure sensible heat fluxes and transverse wind speed is introduced. To meet demands of the data acquisition and disposal of LAS for measuring sensible fluxes and wind ＇speed, the software for the real-time data collection is designed using PCI8340, a data acquisition card, disposing and displaying signals of LAS on Windows platform. It is convenient for persons to get the experimental results quickly and exactly. In addition, it can run automatically because of the data validity check module of the software.
