12. Satellites Main job to observe weather Main job to observe weather Worldwide view Worldwide view 3 types of Imagery 3 types of Imagery

13. Infrared Imagery IR radiation emitted from oceans, land, clouds tops, snow/ice IR radiation emitted from oceans, land, clouds tops, snow/ice Shades of intensities (Colder temps low IR, warmer temps higher IR ) Shades of intensities (Colder temps low IR, warmer temps higher IR ) Used to determine cloud’s temp, type & altitude Used to determine cloud’s temp, type & altitude Highlight strong storms Highlight strong storms

14. IR

15. Visible Light Light from the sun reflected by oceans, land, cloud tops, snow/ice Light from the sun reflected by oceans, land, cloud tops, snow/ice Intensity depends on light striking feature & feature’s reflectivity (snow & ice reflect best & oceans reflect least) Intensity depends on light striking feature & feature’s reflectivity (snow & ice reflect best & oceans reflect least) Photograph of what you would see from space Photograph of what you would see from space Tracks clouds Tracks clouds
