which type of satellite image provides information about the height of clouds
Weather satellite The thermal or infrared images recorded by sensors called scanning radiometers enable a trained analyst to determine cloud heights and types, to calculate land and surface water temperatures, and to locate ocean surface features. Infrared satellite imagery can be used effectively for tropical cyclones with a visible eye pattern, using the Dvorak technique, where the difference between the temperature of the warm eye and the surrounding cold cloud tops can be used to determine its intensity (colder cloud tops generally indicate a more intense storm).[10] Infrared pictures depict ocean eddies or vortices and map currents such as the Gulf Stream which are valuable to the shipping industry. Fishermen and farmers are interested in knowing land and water temperatures to protect their crops against frost or increase their catch from the sea. Even El NiÃ±o phenomena can be spotted. Using color-digitized techniques, the gray shaded thermal images can be converted to color for easier identification of desired information.
Satellite map images with missing or unclear data Some locations on free, publicly viewable satellite map services have missing, incomplete, or unclear map data. In some cases, these regions have been intentionally digitally obscured or blurred.[1] Westchester County, New York, for example, has asked Google to blur potential terror targets (such as an amusement park, a beach, and parking lots) from its satellite imagery.[2]
