The first step,soil temperature was inversed by the ISSTES algorithm from thermal infrared data;The second step,the soil temperature was introduced to make the inversion equation complete in mid-infrared domain;The third step,the least square method was applied to solve the formulations and then the mid-infrared emissivity was obtained.
该方法利用热红外的ISSTES算法获得土壤热红外的发射率光谱和高精度的土壤温度估值,并将得到的温度估值用于中红外的发射率提取,减少中红外待反演参数,形成多余观测,使用最小二乘方法求解土壤中红外的发射率。
