摘要: In the summer of 1994 0.07 cm -1 resolution infrared Airborne Emission Spectrometer (AES) acquired spectral data over two wildfires, one in central Oregon on August 3 and other near San Luis Obispo, California, 15. The spectrometer was board a NASA DC-8 research aircraft, flying at an altitude 12 km. spectra from both fires clearly show features due to water vapor, carbon dioxide, monoxide, ammonia, methanol, formic acid, ethylene significantly higher abundance temperature than observed downlooking normal atmospheric ground conditions. Column densities are derived for several species, molar ratios compared with previous biomass fire measurements. We believe that this is first time such have been by airborne remote sensing.
