研究目的
To introduce the IVVRM tool as a sandbox environment for the PROSAIL family of radiative transfer models, facilitating education, training, and research through interactive visualization and manual curve fitting for biophysical variable inversion.
研究成果
IVVRM serves as an effective interactive environment for the PROSAIL model family, enhancing understanding of model dynamics and facilitating parameter retrieval from vegetation spectra. It is suitable for both educational purposes and scientific research, offering a clear inversion approach through manual curve fitting.
研究不足
The manual curve fitting approach is impracticable for larger data sets, and the tool's performance is dependent on the speed of model calculations, which was a focus during development.
1：Experimental Design and Method Selection:
The IVVRM tool is designed to provide an interactive sandbox environment for the PROSAIL radiative transfer models, enabling real-time visualization of model outputs based on user inputs.
2：Sample Selection and Data Sources:
The tool allows for the import of static reflectance spectra for comparison with model results.
3：List of Experimental Equipment and Materials:
The tool is implemented within the EnMAP-Box
4：0, utilizing Python for the PROSAIL model implementation. Experimental Procedures and Operational Workflow:
Users interact with the GUI to adjust model parameters, with results instantly plotted. The tool supports accumulative plotting for sensitivity analysis.
5：Data Analysis Methods:
Statistical error indices (RMSE, MAE, NSE, mNSE, R2) are calculated automatically for each model run to assess the goodness of fit.
