Imaging Spectroscopy for Earth and Planetary Science: Investigations, Future Missions, and Analysis Methods
Anticipated orbital imaging spectrometers promise a revolution in our understanding of terrestrial and aquatic ecosystems. These include the NASA EMIT Mission, to be launched in 2021 to the ISS, and a global Surface Biology and Geology investigation designated by the Earth Science Decadal Survey. The instruments have a long history of airborne deployments for mapping terrestrial and coastal aquatic ecosystems, geology, and atmospheric properties, and are also critical tools for exploring other planetary bodies. However, consistent global maps of Earth’s surface pose special algorithmic challenges, thanks to challenging tropical atmospheric conditions and diverse surface environments. This talk will describe historical and current instruments, software, and public datasets. We highlight an Optimal Estimation (OE) statistical inversion methodology from recent work which demonstrates closed uncertainty accounting and accurate retrieval of surface and atmospheric parameters across tropical, subtropical, and mid-latitude environments.
