NASA Airborne Facility Instruments at the ORNL DAAC: Opportunities for Open Access and Open Science

The ORNL DAAC is the assigned DAAC for three NASA airborne Facility Instruments that are NASA airborne optical sensing instruments: MASTER (MODIS/ASTER Airborne Simulator), AVIRIS (Airborne Visible InfraRed Imaging Spectrometer) -Classic, and AVIRIS-Next Generation. For each instrument, two file sets; orthocorrected scaled radiance (L1B) and reflectance (L2) along with ancillary data, will be available for thousands of flight lines. As Facility Instruments, MASTER and AVIRIS instruments are available to a broad range of applications within NASA’s science research community. Discoverability is improved by a single archive facility that synthesizes critical components of metadata information as well as integrated flight catalog development. AVIRIS, MASTER, and other spectrometry instruments are similar in their opportunities for cloud-optimized data storage (chunked, compressed, N-dimensional) and file representation.
