Title: Measuring snow properties in Greenland
Professor Box (left) in collaboration with Professor Alun Hubbard and his student Johnny Ryan (right) have been flying fixed-wing drones over Greenland ice each year since 2013. In this instance, the drone is equipped with up- and down-looking radiometers and a camera, useful for retrieving a fine resolution map of surface reflectance, which is used to decompose moderate resolution satellite data.
