    Description

    We report the construction of a database of infrared spectra aimed at detecting the gases emitted by biomass burning. The project uses many of the methods of the Pacific Northwest National Laboratory (PNNL) infrared database, but the selection of the species and special experimental considerations are optimized. Each spectrum is a weighted average derived from 10 or more individual measurements. Each composite has a spectral range from ≤600 to ≥6500cm−1 with an instrumental apodized resolution of 0.11cm−1. The resolution was chosen to bring out all spectral features, but recognizing that pressure broadening at 760 Torr results in essentially all ro-vibrational lines having these or greater linewidths.
