Abstract
Welcome to the September 2021 issue of <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">IEEE Geoscience and Remote Sensing Magazine</i> ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">GRSM</i> )! We have a number of feature articles in this issue, covering topics ranging from a tutorial on synthetic aperture radar (SAR) beamforming, to a review of the Earth-observation constellation, to several articles on techniques for processing various types of remote sensing data. These will be followed by a report on our annual International Geoscience and Remote Sensing Symposium (IGARSS) conference, held virtually this year. Finally, a few of our regular columns will update you on the activities of our members and Chapters throughout the world.
