Embodiment 1
[0038] The operation was performed on a computer equipped with Intel’s second-generation Core i3-2100@3.10GHz processor, 16.0GB RAM, and NvidiaGeForce GT 630 graphics card. Taking POLDER's multi-angle ice and snow reflectance data as an example, according to figure 1 In the process shown in the process, the multi-angle ice and snow reflectance data is processed, and the fitting effect of the nuclear-driven model on the observation data is compared before and after the correction method is used.
[0039] figure 2 with image 3 The comparison diagrams of the fitting effect of the nuclear-driven model on the observed data before and after the use of the correction method are respectively. It can be seen from Figure 2 that the pre-correction method has relatively poor fitting results to the POLDER ice and snow reflectance data, and cannot accurately characterize the bidirectional reflection characteristics of ice and snow; and the data before correction ( figure 2 ) Compared to the...
