Brown Bag Seminar: Stephen Ungar

The Earth Observing-One (EO-1) satellite, launched in November of 2000, will complete its sixteenth and final year of operation at the end of calendar year 2016. EO-1’s Advanced Land Imager (ALI) served as the prototype for the Operational Land Imager (OLI) on board Landsat 8. Lessons learned from the ALI operations and calibration strategies, developed over the course of the mission, served as a pathfinder for operating and calibrating OLI.

Observations from the Hyperion Imaging Spectrometer on board EO-1 have contributed to hundreds of papers in refereed journals, conference proceeds and other presentations. The EO-1 Hyperion imaging spectrometer is the first and longest operating instrument that provides visible to shortwave infrared science-grade data from orbit. Hyperion has been used to study a variety of natural and anthropogenic phenomena including hazards and catastrophes, agricultural health and productivity, ecological disturbance/development, and land use/land cover change.

As an example, Hyperion has been used in hazard and catastrophe studies to monitor and assess effects of tsunamis, earthquakes, volcanic eruptions, mudslides, tornadoes, hurricanes, wild-fires (natural and human ignited), oil spills, and the aftermath of world trade center bombing.

After I tell you how it all got started, I will summarizes the current status of EO-1 and some of its key historic findings. I will also solicit your input and advocacy in formulating future plans (for presentation to NASA HQ) to exploit the upward of 90,000 scenes expected to be archived at USGS EROS by the end of the mission.
