Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including greenhouse gases that help warm the Earth. Studies suggest that biomass burning has increased on a global scale over the last 100 years, and computer calculations indicate that a hotter Earth resulting from global warming will lead to more frequent and larger fires.

Chlorine nitrate has been measured by CLAES and chlorine monoxide by MLS. The CLAES and MLS measurements together help to show that the polar stratospheric clouds which form in the cold Arctic stratosphere have converted most of the chlorine nitrate into the radical chlorine monoxide. In 1992, UARS measurements showed conclusively that an an Arctic ozone hole is beginning to form. || ", "hits": 79 }, { "id": 840, "url": "http://svs.gsfc.nasa.gov/840/", "result_type": "Visualization", "release_date": "1999-04-09T12:00:00-04:00", "title": "Various Film Clips from the UARS Video", "description": "A series of B-roll film clips used as source material for the UARS video (SVS animation 579). || a000840.00090_print.png (720x480) [465.3 KB] || a000840_pre.jpg (320x238) [13.8 KB] || a000840_thm.png (80x40) [6.9 KB] || a000840_pre_searchweb.jpg (320x180) [88.0 KB] || a000840.webmhd.webm (960x540) [159.9 MB] || a000840.dv (720x480) [2.1 GB] || a000840.mp4 (640x480) [122.1 MB] || ", "hits": 78 }, { "id": 841, "url": "http://svs.gsfc.nasa.gov/841/", "result_type": "Visualization", "release_date": "1999-04-09T12:00:00-04:00", "title": "UARS Video Credits", "description": "Credits for the UARS video || a000841.00080_print.png (720x480) [525.9 KB] || a000841_thm.png (80x40) [4.9 KB] || a000841_pre.jpg (320x242) [8.3 KB] || a000841_pre_searchweb.jpg (320x180) [58.9 KB] || a000841.webmhd.webm (960x540) [23.6 MB] || a000841.dv (720x480) [329.7 MB] || a000841.mp4 (640x480) [18.0 MB] || a000841.mpg (352x240) [12.4 MB] || ", "hits": 17 }, { "id": 842, "url": "http://svs.gsfc.nasa.gov/842/", "result_type": "Visualization", "release_date": "1999-04-09T12:00:00-04:00", "title": "UARS Voice Over", "description": "This entry represents the narration track for the UARS video (SVS animation 579).
