The NPOESS Aircraft Sounder Testbed - Interferometer (NAST-I) is an airborne infrared interferometer maintained and operated by NASA Langley Research Center (LaRC). It uses Fourier transform spectroscopy to provide measurements of brightness temperature and radiance. NAST-I operates within the spectral range of 3.7-16.1 µm and has a spectral resolution of 0.25 cm-1. It has a spatial resolution of 2.6 km and a cross-track swath width of 46 km at a flight altitude of 20 km. A complete scan period for NAST-I takes around 12.2 seconds.
