Landsat has been accurate and reliable for over 50 years because of the diligent calibration and validation work done by the team at EROS. One of the ways the team validates what they have so carefully calibrated is to take measurements on the ground while Landsat passes by overhead. For this Eyes on Earth podcast episode, we go out to the EROS test site during a Landsat pass to get a sense of what that work is like. Learn about the instruments used for this work and why it’s important to keeping Landsat as the gold standard for Earth observations.
