This dataset contains geocorrected image overlays of Level 2 (L2) emissivity and land surface temperature (LST) from imagery acquired by the Hyperspectral Thermal Emission Spectrometer (HyTES) instrument. The emissivity overlays are composite RGB images derived from bands 183 (10.8 microns), 100 (9.2 microns), and 58 (8.6 microns). This is the NASA Earth Observing System Data and Information System (EOSDIS) facility instrument archive of these data. The NASA HyTES is an airborne imaging spectrometer with 256 spectral channels between 7.5 and 12 micrometers in the thermal infrared part of the electromagnetic spectrum and 512 pixels cross-track. HyTES has been deployed on NASA's Twin Otter, Earth Resources ER-2, and GulfStream V aircraft and completed its first flights in July 2012. HyTES was designed to provide high spectral and spatial resolution thermal infrared (TIR) data as a precursor for NASA's planned Hyperspectral Infrared Imager (HyspIRI) orbital mission. It is useful for a number of applications, including high-resolution surface temperature and emissivity measurements, point sources of air pollution, and volcano observations. The overlays are provided in compressed Keyhole Markup Language (KMZ) format.
