Abstract
JPL's Hyper-Spectral Thermal Emission Spectrometer (HyTES) is an airborne imaging spectrometer with 256 spectral bands in the Thermal Infrared (TIR) wavelength region and 512 spatial pixels across track. It was designed to image the ground with each spatial pixel capturing a high-resolution spectrum of light over the full 7.5 to 12 µm spectral range. HyTES is now using a new detector technology. The sensor is characterized with the new detector and results from a recent campaign are discussed. Data included enhanced methane detection from permafrost in Sweden as well as angular land surface temperature (LST) measurements in controlled agricultural sites.
