美国海洋大气局卫星上的遥感器能检测大城市放出的热量,可以使城市规划人员了解城市的人口增长和工业发展情况。研究人员也在利用这些温度数据(包括从航宇局卫星上获得的温度数据)研究自然资源,包括研究陆地的含水量和矿藏量。目前,海洋大气局的研究人员正根据最新的泰罗斯-N极地轨道卫星(去年10月发射)接收的图象,研究城市“热岛”。卫星图象经过放大和计算机增强,与普查的城市地图比较,研究人员便能鉴定出城市的延伸情况。海洋大气局的科学家们说,卫星图象是
Remote sensing from satellites at the United States National Oceanic and Atmospheric Administration (NOAA) can detect the heat released by large cities and can make city planners aware of the urban population growth and industrial development. Researchers are also using the temperature data (including temperature data obtained from NASA satellites) to study natural resources, including the study of land moisture and mineral reserves. Currently, NOAA researchers are studying the city’s “heat island” based on the images received by the new Tyrrron-N polar orbiting satellites (launched last October). Satellite images have been enlarged and computer-enhanced, and compared to the census of the city map, researchers can identify the city’s extension. The NOAA scientists said the satellite imagery is
