The Integrated Cavity Output Spectrometer (ICOS) is an airborne in situ spectrometer developed by Harvard University. It is a mid-infrared (6.7 μm) spectrometer that measures the primary isotopologues of water vapor in the upper troposphere and lower stratosphere. It has been integrated onto NASA’s WB-57 aircraft for field investigations of water vapor. It has an average data acquisition rate of 1 Hz and a measurement precision of 0.14 ppbv in 4-second averages for water vapor.
