The PNNL Quantitative IR Database for Infrared Remote Sensing and Hyperspectral Imaging
Pacific Northwest National Laboratory (PNNL) is presently compiling a quantitative and high spectral resolution (0.10 cm-1) set of infrared reference data that are specifically designed for atmospheric monitoring, remote sensing, and hyperspectral imaging. The final list of target compounds will contain nearly 500 gas-phase species, whereby each species is reported as a composite reference spectrum at 25?C, with most species also having reference data for 5?C and 50?C. Each composite spectrum is a quantitative Beer's law fit to typically 10 or more individual infrared measurements, whereby each spetrum corresponds to a different pressure of the gas that has been pressurized to 760 Torr with N2 so as to emulate atmospheric pressure broadening. Details of the data acquisition protocol and spectral analysis are discussed.
