Biophysical Processor Description

Processor Description

The Biophysical Processor S2 utilizes 8 bands at 20m resolution and it is capable of computing the LAI , Cab , CWC , FAPAR and FVC indexes. You can find more information about the algorithm in the Algorithm Specification documentation page.  

I/O Parameters Tab

Source Product Group

Name: Used to select the spectral source product. The source product shall be a Sentinel-2 L2A product. Use the ... button to open a data product currently not opened in the application. The algorithm is calibrated for top-of-canopy reflectances and depends on the acquisition geometry, so it requires slope-effect corrected reflectances to give optimal results

Target Product Group

Name: Used to specify the name of the target product.

Save to: Used to specify whether the target product should be saved to the file system. The combo box presents a list of file formats.

Open in SNAP: Used to specify whether the target product should be opened in the application. When the target product is not saved, it is opened automatically.

Processing Parameters Tab

Sensor:
Choose between Sentinel 2A (S2A), Sentinel 2B (S2B), and Sentinel 2C (S2C) satellite depending on the product source

Output resolution:
The output resolution

Compute LAI:
Enable/Disable the computation of LAI (Leaf Area Index) in the output product

Compute Cab:
Enable/Disable the computation of Cab (Chlorophyll content in the leaf) in the output product

Compute CWC:
Enable/Disable the computation of CWC (Canopy Water Content) in the output product

Compute FAPAR:
Enable/Disable the computation of FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) in the output product

Compute FVC:
Enable/Disable the computation of FVC (Fraction of Vegetation Cover) in the output product
