QUESTIONS: Slido will be used to answer your questions during the seminar.



Our recent research in remote sensing and in signal analysis will be reviewed.  Simple physics of specular reflection was used to demonstrate that nearly horizontally oriented ice crystals floating in clouds reflect enough light to (occasionally) saturate the CCD camera of the Deep Space Climate Observatory, residing at the first Lagrangian point one million miles from Earth.  Another optics-cloud connection has been used to link rings of faint but widespread glories in satellite images to droplet sizes in marine stratocumuli. Finally, a signal-noise decomposition will be described, based on a simple idea that only perfect noise generates data with a jointly uniform rank-time probability distribution.
