AGU 100 - GC53A - Advances Toward Global Imaging Spectroscopy and Thermal Infrared Measurements I

A new generation of remote solar-reflected spectroscopy and thermal infrared measurement is revolutionizing terrestrial and aquatic ecology, surface geology, hydrology and land use studies.  Airborne precursors presage upcoming orbital investigations by space agencies worldwide, including International Space Station (ISS) missions like ECOSTRESS (USA, 2017), DESIS (Germany, 2018), HiSUI (Japan, 2021), and EMIT (USA, 2021), and polar orbiters such as PRISMA (Italy), EnMAP (Germany, 2020),  and FLEX (ESA, 2023), and anticipated investigations like SBG (USA) and CHIME (ESA).  We will survey progress of individual missions and ongoing preparatory research by recent imaging spectrometer and thermal IR airborne campaigns.   We will also highlight progress translating local models to address Earth system questions at regional and global scales.  Our themes include: coral reef surveys; volcano investigations; surface ecology and biodiversity studies; aquatic ecosystem and water quality monitoring; hydrology studies, including ice and snow characterization; land use studies; and more.
