Reflectance to Radiance Operator


The Reflectance to Radiance Processor converts the Top Of Atmosphere (TOA) reflectance to radiance from a given product.


Reflectance to Radiance Algorithm Specification


I/O Parameters

Source Products

Source: Specify the source product which will be used for the computation.

Target Product

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

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

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

Solar irradiance (if neither Sentinel-2 nor SPOT): Specify the solar irradiance, only if the source product is neither Sentinel-2 nor SPOT. For Sentinel-2 and SPOT products the solar irradiance is extracted from metadata.

U (if not Sentinel-2): Specify the quantification value (U). For Sentinel-2 products this value is extracted from metadata.

Incidence angle (if neither Sentinel-2 nor SPOT): Specify the incidence angle in degrees, only if the source product is neither Sentinel-2 nor SPOT. For Sentinel-2 products the incidence angle is replaced with the values from the sun_zenith band. For SPOT products the value is extracted from metadata.

Source bands: Specify the source bands for the computation.

Copy masks: If set, all the masks from the source product are written to target product.
