Abstract

• We reproduced the chemical-physical conditions of fumarolic emission at Phlaegrean Fields, Pozzuoli, Italy, and we measured the CO2 and H2O concentrations using an absorption spectrometer based on two distributed feedback laser diodes at wavelengths of 1.578 and 1.393 mu m. We discuss the accuracy levels of the different methods used. Furthermore, we measured the broadening coefficients for H2O (self-broadening, 28.2 +/- 0.6 MHz/Torr; CO2 broadening, 6.0 +/- 0.4 MHz/Torr) and CO2 (self-broadening, 3.2 +/- 0.1 MHz/Torr; H2O broadening, 4.0 +/- 0.1 MHz/Torr). Using the present data, we evaluated a minimum detectable variation of 9% for H2O and 1% for CO2. (C) 1997 Optical Society of America. (literal)
