Differential Absorption Lidar in stock Production Introduction 聽 Leice is developing an advanced greenhouse gas Lidar for accurately quantifying greenhouse gas emissions from natural and anthropogenic sources and sinks to meet the requirements for local, national, and international mitigation efforts. It鈥檚 based on a technology known as differential absorption LIDAR (DIAL), which can provide species specific concentrations of greenhouse gases with range resolution. When these measurements are coupled to precise wind velocity measurements, the flux of the greenhouse gases, the important quantity for regulators, can be determined. 聽 The CO2 Gas Flux Lidar developed by Leice, can provide simultaneous high-precision detection of wind field and CO2 column concentration in the boundary layer, and calculation of CO2 flux based on wind field and CO2 column concentration. The greenhouse gas Lidar can also realize three-dimensional monitoring of regional carbon dioxide emissions, emission trend analysis, peak target research and judgment. It measures CO2 column concentration, sec and time average wind speed and direction, vertical velocity, turbulence intensity, CO2 flux. 聽 The greenhouse gas Lidar is based on the same principal as elastic backscatter LIDAR, but operates at two wavelengths, one on resonance and one off resonance of the molecular absorption of the greenhouse gas of interest. Because the on resonance wavelength is more strongly absorbed by the greenhouse gas, the difference between both signals is proportional to its number density. Thus, this technology could provide regulators with quantity of greenhouse gases being released at a particular location and pinpoint their sources. 聽Differential Absorption Lidar in stock website:http://www.leicelidars.com/differential-absorption-lidar/
