The EOSDIS Update - Winter 2020 quarterly newsletter is here! Complementing the launch of the Sentinel-6 Michael Freilich mission that will create some of the most accurate sea level measurements ever acquired, you’ll find out how satellites actually perform these measurements using such things as the ellipsoid, quasars billions of light-years away, and the gravity potato. You’ll also read about an exciting joint NASA/U.S. Forest Service effort to create a U.S./Canadian version of the Fire Information for Resource Management System (FIRMS) and about the release of Daymet 4.0 at NASA’s Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC). Along with these feature articles, you’ll also find links to Data User Profiles, webinars, data recipes, Toolkits, and, of course, some amazing images of Earth.
