· FABLE is an instrument to measure carbon dioxide (CO2) and water vapour (H2O). The core instrument unit consists of a commercial NDIR (Non Dispersive Infrared) CO2/H2O Analyzer model LI6262 of the LICOR Biosciences company. The concentrations of CO2 and H2O are determined using broad band infrared absorption spectroscopy. Two identical gas cells were used, whereas the …

· I read a European? volcanologist’s paper via Googling months back stating that H2O and CO2 totalling upto 20% of the ejecta in mass were required to support a plinian column. His measurements of outgassing found CO2 to range << to of the vapor content. With no plinian eruptions yearly outgassing is supposed to be Gtons and is dismissed. My rough calculations (I …

by CO2 infrared bands. VV represents exchange of vibrational energy and VT represents the conversion of vibrational energy into kinetic energy in collisions. The NIR bands of absorption in CO 2 significantly affect the thermal budget of the mesosphere. NIR absorption by CO 2 can contribute up to 30% of the total solar heating in the mesosphere. Between the heights of 6085 km the heating can ...

(1) The interference gases for NDIR analyzers are CO, CO2, H2O, CH4, and SO2. Note that interference species, with the exception of H2O, are dependent on the N2O infrared absorption band chosen by the instrument manufacturer. For each analyzer determine the N2O infrared absorption band. For each N2O infrared absorption band, use good engineering judgment to determine which interference gases ...
