PowerPoint PresentationSlide 2Slide 3Slide 4Satellite OrbitsGOES EastGOES WestLow-Earth Orbit (polar orbit)Geosynchronous Orbit Primarily research satellites Most orbit from pole to pole and let the Earth spin beneath themVery high spatial resolution (250m to 15m) Only see a small swath of the earth’s surface at any given time Primary satellite orbit used for wx observation Look at the same point on the equator @ the same longitude and see’s nearly half of the Earth. Orbital period matches the Earth’s rotationSatellite Channels: Visible ImageryMeasures: reflected visible sunlight*** No images at night!!!Bright = objects with a high albedo**snow, thick clouds, ice capsDark = objects with a low albedo**vegetation, land, thin clouds, oceans Notes: Features are distinguished by their albedo. Albedo = reflected sunlight incident sunlightCompletely absorbingNo absorptionWINDOWGOES West GOES EastSatellite Channels: Infrared ImageryMeasures: emitted IR radiationMeasures the temperature of an objectBright = cold objectshigh clouds like the tops of t-storms and high thin cirrus clouds Dark = warm objectslow clouds, the surface and snowNotes: All objects emit radiation according to their temperature. ** Hotter objects emit more radiation than colder objectsColdColdWarmWarmvisible image IR imageIR Image Enhanced with color(color corresponds to temperature of the cloud top)Satellite Channels: Water Vapor ImageryMeasures: emitted radiation from water vaportells us the moisture content of the airBright = high water vapor contentt-storms and thick cloudsDark = low water vapor contentcold, clear and dry areas Notes: Serves as an excellent tracer of atmospheric
