Measurements and Applications
Pushbroom spectropolarimetric camera on a 2-axis gimbal for multiangle viewing, frequent revisits over targets, and inflight calibration. Major metropolitan areas are sampled with sub-km spatial resolution to study impacts of different types of particulate matter on human health.
