Paper Abstract
Specifications and examples of application of laser gas-analyzers of near- and mid-infrared ranges for diagnostics of
greenhouse gases (C02, C2H4, and CH4) emission by vegetation biosystems both under standard conditions and
under impacts of natural and anthropogenic stresses are considered in the report. The gas-analyzer complex includes:
1) gas-analyzer with a multipass absorption cell based on the frequency-tunable diode laser (1600-1 650 nm) for
measuring sub-background methane concentrations (≤20 ppbV);
2) gas-analyzer based on the wave-guide C02-laser equipped with the intracavity acoustic detector capable of fast
frequency scanning in the 9 and 10 μm generation bands and having the ethylene-sensitivity better than 1 ppbV.
The technology of measurements of gas emission by plant stripped leaves and coniferous needles is described and
the measurements of CO2 and CH4 emissions are presented.
