The dataset is based on simulations from the SCOPE (Soil-Canopy Observation of Photosynthesis and Energy fluxes) model, covering a variety of parameters as described in Table 4 of the article (SCOPE-Exp1). The variables include:
- leaf chlorophyll content (Cab)
- Leaf internal structure
- Canopy Leaf Area Index (LAI) and Leaf Angle Distribution (LAD)
- Sun and viewing zenith angles
- Relative azimuth angles
- Soil reflectance
The data is stored in MATLAB .mat files with a structured format, including the following variables:
- Soil Reflectance: Soil spectral reflectance
- TOC Reflectance: Top-of-canopy reflectance
- ** Soil Single Scattering**: Direct soil reflection to TOC reflectance
- ** Leaf Single Scattering**: Direct scattering of leaves to TOC reflectance
- Multiple Scattering: Contribution of multiple scattering to TOC reflectance
- Canopy LAI: Canopy leaf area index values
- Leaf Cab: Chlorophyll content of leaves
The code provides three methods to estimate the contribution of soil single scattering to TOC reflectance:
- Method-RBB
- Method-TBB
- Method-LAB
