| The Inversion of CaO Content from Clementine Thermal Infrared Data around the Apollo 17 Landing Site |
| In order to study the inversion of CaO content in the lunar rock by using Clementine thermal infrared data, the authors selected two Clementine infrared images, which covered the Apollo17 landing site as the study area. The lunar physical temperature model was employed to simulate the temperature as the input parameter which was used to conduct inversion of the emissivity. 35 LPI Apollo samples except Apollo17 were used to calculate the relationship between the content of CaO and the emissivity. It was shown that the relationship between them was in linear correlation(R2=0.661). Thus the inversion of the content of CaO was carried out based on the Clementine infrared emissivity. To evaluate the results, the authors calculated the relative error between the derived value and the actual value of CaO. Among the 8 relative error results, the minimum is 1.77%, the maximum is 9.29% and the root mean square error is 0.767. Studies show that the methods used for the inversion of emissivity and content of CaO in this paper are feasible. The result achieved by the authors provides a new idea for quantitative inversion of the ingredients of lunar minerals. |
