大气程辐射遥感图像技术

Techonology of Atmospheric Path Radiation Remote Sensing Image

大气程辐射遥感图像是遥感图像中各点大气程辐射遥感值按顺序排列所形成的、与地面状况无关的、仅与大气状况有关的、无法在自然条件下直接获取的遥感图像.就对地探测而言,大气程辐射是需消除的干扰因素,对于大气传输特性的研究、遥感图像的大气修正、区域大气遥感探测和大气环境质量遥感监测等则是宝贵的信息源.研究利用遥感数字图像和对应地面反射率、逐点分离、提取像元大气程辐射遥感值从而生成大气程辐射遥感数字图像有重要理论和应用价值.

Atmospheric path radiation remote sensing images are based on values of atmospheric path radiation in remote sensing data dependent only on the state of atmosphere but not ground conditions. Although atmospheric path radiation causes interference to observation of the earth, it provides crucial information such as atmospheric transmitting characteristics, atmospheric modification of remotely sensed images, regional atmospheric status, and atmospheric environment quality. Therefore, it is important both in theory and practice to generate atmospheric path radiation images by extracting atmospheric path radiation values from the remote sensing images and the corresponding surface reflectance.
