The NPOESS Airborne Sounder Testbed Interferometer (NAST-I) provides high spatial resolution (~2.0 km footprint) scanning and high spectral resolution (0.25 cm-1) measurements in the spectral region of 645-2700 cm-1 from Proteus high-altitude (~16 km) aircraft during CLAMS. In this presentation, the scientific measurement capabilities of the NAST-I system are demonstrated. NAST-I retrievals obtained during the CLAMS field campaign are presented in conjunction with comparisons to independent radiosonde and the sea surface temperature data. It is shown that observations of mesoscale structure of the atmosphere and Earth's surface are achievable with these accurate interferometric measurements. The NAST-I data, achieved during the CLAMS field campaign, are used to provide satellite instrument and algorithm experimental validation.
