ECOSTRESS, HyTES and HyspIRI/SBG - Imaging in the Thermal Infrared
Abstract
In 2018, the US National Research Council released the second Earth Science Decadal Survey (ESDS). The second survey recommended launching a mission with similar specifications to the Hyperspectral Infrared Imager (HyspIRI) mission recommended in the first ESDS, referred to as the Surface Biology and Geology (SBG) mission. HyspIRI is a global mission designed to address a critical set of questions on how the surface of the earth is responding to natural and human-induced changes. The SBG mission requires hyperspectral measurements between 0.38 and 2.5 μm at a spatial scale of 30 m with a minimum revisit of 16-days and a thermal infrared (TIR) multispectral measurements between 4 and 12 μm at a spatial scale of 60 m with a minimum revisit of 5-days. As part of the risk reduction activities for the TIR instrument a space-ready Prototype HyspIRI Thermal Infrared Radiometer (PHyTIR) was developed in the laboratory for hardware risk reduction and an airborne Hyperspectral Thermal Emission Spectrometer (HyTES) for science risk reduction. In July 2014, the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) was selected as part of the NASA Earth Ventures Instrument program and launched in June 2018. ECOSTRESS is based on PHyTIR and is being used to address critical science questions related to evapotranspiration. ECOSTRESS has 5 TIR spectral bands, a spatial resolution of 68m x 38m (crosstrack x downtrack) and a revisit of every few days at varying times of day from the International Space Station. HyTES is an airborne instrument with 256 spectral bands in the TIR and pixel sizes of 2-30 m depending on flight altitude. HyTES is one of the few hyperspectral thermal infrared imaging spectrometers. Recently HyTES was modified to fly on the NASA ER2 and completed a campaign in Hawaii, it also flies on a Twin Otter. This presentation will describe the current status of these activities.
