图6 在50°入射角下,使用“5-Max/Min”法FFX(fr)和FFX(th)参考值时四种冻结因子不同阈值下与参考数据集Tair(a),Tsoil2.5cm(b)和Tsoil5.0cm(c)匹配的准确度(虚线为固定阈值)
Fig.6 Under the incident angle of 50°, using the “5-Max/Min” method FFX(fr) and FFX (th) reference values,the four frost factors are compared with the reference data set Tair (a), Tsoil2.5cm (b)and Tsoil5.0cm (c) under different thresholds (The dotted line is a fixed threshold)
