| 摘 要： | 文中在考虑环境一号B星(HJ-1B)热红外波段(infrared scanner,IRS4)光谱响应函数和有效波长的基础上,通过MODTRAN4模型模拟,对Jimenez-Munoz和Sobrino(JM&S)单通道算法中的大气函数进行改进,重新计算得到了适合HJ-1B星IRS4地表温度(land surface temperature,LST)反演的3个大气函数公式,并反演了福州地区的地表温度.采用基于星上辐亮度法对反演的地表温度进行精度评价,并将反演的地表温度与JM&S算法、段四波等修正的JM&S算法反演的地表温度进行对比分析.结果表明:使用文中改进后的大气参数对HJ-1B星IRS4进行地表温度反演,可取得较好结果.

| Abstract: | In this paper,we present a modification of the Jimenez-Munoz and Sobrino(JM&S) single-channel method for land surface temperature(LST) retrieval from HJ-1B IRS4 data for zone Fuzhou.The modification takes into account the effective wavelength and spectral response of HJ-1B IRS4 and was developed using a MODTRAN 4 simulation to estimate the three atmospheric parameters of the JM&S method.We validated the LST generated from HJ-1B IRS4 by this method with an alternative radiance-based method,which calculates g... |
