A weather satellite is a type of [[satellite]] that is primarily used to monitor the [[weather]] and [[climate]] of the [[Earth]].<ref name="NESDIS">NESDIS, [http://www.nesdis.noaa.gov/satellites.html Satellites.] {{Webarchive|url=https://web.archive.org/web/20080704195947/http://www.nesdis.noaa.gov/satellites.html |date=2008-07-04 }} Retrieved on 4 July 2008 {{PD-notice}}</ref> These meteorological satellites, however, see more than [[cloud]]s and cloud systems. City lights, [[fire]]s, effects of [[pollution]], [[auroral light|aurora]]s, [[Dust storm|sand and dust storms]], [[snow]] cover, [[ice]] mapping, boundaries of [[ocean current]]s, [[energy]] flows, etc., are other types of environmental information collected using weather satellites.

Weather satellite images helped in monitoring the volcanic ash cloud from [[Mount St. Helens]] and activity from other volcanoes such as [[Mount Etna]].<ref>NOAA, [http://www.spaceref.com/news/viewpr.html?pid=15216 NOAA Satellites, Scientists Monitor Mt.
