The Enhanced MODIS Airborne Simulator (eMAS) is an airborne cross-track scanning spectrometer operated by the Airborne Sensor Facility (ASF) at NASA Ames Research Center. eMAS collects high-resolution imagery of cloud and surface features which can be used to help develop and test algorithms for Moderate Resolution Imaging Spectroradiometer (MODIS) satellite observations. 

eMAS operates across 38 spectral channels at 0.445-14.1 µm wavelengths and has a scan rate of 6.25 Hz. eMAS has a spatial resolution of 50 m and a swath width of 37.25 km at an altitude of 20 km.
