摘要
陆地表面温度被认为是城市环境分析的重要指标之一。目前,利用热红外遥感技术反演地表温度是获取有关区域地表温度信息的一个有效可行的方式。针对不同热红外传感器,国内外很多学者做了大量的相关实验,其中以覃志豪单窗算法精度相对较高;因此,采用覃志豪单窗算法反演地表温度,从而分析九江市的热度情况。实验结果显示,九江市2014年10月份气温在9~23℃区间,与实测温度接近,对九江市热岛研究具有一定的参考意义。
Land surface temperature is considered to be one of the important indicators of urban environment analysis. At present,the surface temperature inversion by using the thermal infrared remote sensing technology is to obtain information about regional land surface temperature of an effective and feasible way. According to different thermal infrared sensors,a lot of domestic and foreign scholars to do a lot of relevant experiments,of which Qin Zhihao Mono-window algorithm accuracy is relatively high. Therefore,this article uses the Qin Zhihao Mono-window algorithm surface temperature inversion,and analysis the heat of the jiujiang. The experimental results show that the jiujiang in October2014 the temperature within the range of 9 ℃- 23 ℃,and close to the measured temperature,studies of jiujiang city heat island has certain reference significance.
