The following interview segments provide comments on the mission from key Glory personnel. Glory is a remote-sensing Earth-orbiting observatory designed to achieve two separate mission objectives. One is to collect data on the chemical, microphysical, and optical properties of aerosols, along with their spatial and temporal distributions. Glory's second mission objective is to continue collection of total solar irradiance data for the long-term climate record. Glory accomplishes these objectives by deploying two instruments aboard a low earth orbit satellite: the Aerosol Polarimetry Sensor (APS) and the Total Irradiance Monitor (TIM). Scientists are working to better understand exactly how and why Earth's climate changes, and the Glory mission will provide significant contributions toward this critical endeavor. || ", "hits": 12 }, { "id": 10523, "url": "https://svs.gsfc.nasa.gov/10523/", "result_type": "Produced Video", "release_date": "2009-11-04T00:00:00-05:00", "title": "The Particle Puzzle", "description": "This short video, which is part of a seven part video podcast series about NASA's Glory mission, explores the complexity of small airborne particles called aerosols.

When soot absorbs sunlight, it heats the surrounding air and reduces the amount of sunlight reaching the ground. The heated air makes the atmosphere less stable, creating rising air (convection) which forms clouds and brings rainfall to regions that are heavily polluted.
