saturation event

Oversaturation event over a greenhouse in Russia. The Landsat 8 thermal band shown in the top right image was not affected by the event.

Oct 14, 2014 • The Landsat calibration team published a number of papers in the SPIE Conference Volume 9218: Earth Observing Systems XIX. Our calibration team (or cal team) is a group of scientists and engineers who work together to ensure the scientific quality of Landsat data—they are the people who make it possible for us to compare Landsat images day-to-day and year-to-year. Simply said, they make change-over-time research possible.

Part of the Landsat program’s legacy has become a tradition of rigorously calibrated data—i.e., information that accurately reflects physical conditions of the ground. A team of calibration scientists from NASA, USGS, partner vendors, and universities work together to monitor the performance of Landsat’s science instruments. This is accomplished by assiduously tracking the data collected by the satellites’ instruments, specifically, measurements of reflected light from sources that scientists already know well.

Here is a rundown of the paper titles, authors, and abstracts links from the August SPIE meeting in San Diego, CA:
