Data Acquisition and Process of Large Aperture Scintillometer

Abstract

Abstract:

Sensible and latent heat fluxes exchange between surface and atmosphere is a hot topic in eco-environmental research recent years. A software using large aperture scintillometer 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 of the 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.

Key words: large aperture scintillometer, sensible heat fluxes, data acquisition, VC, software design
