Overview
The open circuit vorticity related system is a research level system for studying near surface flux observations. It uses vorticity covariance technique to study the material and energy exchange between the atmosphere and the underlying surface, and can measure sensible heat flux, latent heat flux, momentum flux, frictional wind speed, and CO2/H2O/CH4 flux.

System Overview:
Open circuit vorticity related systemIt is a research level system for studying near surface flux observations. It uses vorticity covariance technique to study the material and energy exchange between the atmosphere and the underlying surface, and can measure sensible heat flux, latent heat flux, momentum flux, frictional wind speed, and CO2/H2O/CH4Flux. Open circuit vorticity correlation method is a research application of micro meteorological method to investigate the impact of ecosystem on sensible heat, latent heat, momentum flux and CO between the ground and atmosphere2/H2O/CH4Techniques and methods for long-term observation of flux effects. By obtaining typical ecosystem sensible heat, latent heat, momentum flux, and CO2/H2O/CH4The long-term observation data of flux provides basic data for meteorological departments to conduct research on climate system models.
System Advantages:
(1) Based on QCLAS technology, using narrow linewidth ICL or QCL;
(2) Strong light source stability and high spectral resolution;
(3) High selectivity and strong anti-interference ability;
(4) Based on the WMS inversion algorithm, internal wavelength locking and light intensity adaptive algorithms are used to improve long-term stability outdoors without frequent maintenance;
(5) The response speed is adjustable from 0-20Hz, which can meet the requirements of high-frequency processing in the field by balancing small eddies and high wind speeds;
(6) Strong outdoor anti-interference ability, while adding wavelength locking and adaptive algorithms to improve long-term stability.
