(A)ATSR SST - Processor Description |

### User Interface

The SST processor can be invoked in the Optical Toolbox from the tool menu by selecting Processing->Thematic Water Processing->(A)ATSR SST Processing.... On the command line the SST processor is available by means of the Graph Processing Tool `gpt` which is located in the Optical Toolbox `bin` directory. Typing `gpt Aatsr.SST -h` displays further information.

Selecting the SST Processor from the Optical Toolbox tool menu pops up the following dialog:

##### Source Product Group

(A)ATSR source product: Here the user specifies the source product. The combo box presents a list of all products open in the application. The user may select one of these or, by clicking on the button next to the combo box, choose a product from the file system.

##### Target Product Group

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 available file formats. The text field or the button next to it allow to specify a target directory.

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

##### Processing Parameters Panel

Generate dual-view SST: Here the processing of dual-view SST can be activated or deactivated.

Dual-view coefficient file: Here one of the available coefficient sets for dual-view processing can be selected.

Dual-view mask: Here a ROI-mask expression can be defined that will be evaluated during dual-view processing.

Generate nadir-view SST: Here the processing of nadir-view SST can be activated or deactivated.

Nadir-view coefficient file: Here one of the available coefficient sets for nadir-view processing can be selected.

Nadir-view mask: Here a ROI-mask expression can be defined that will be evaluated during nadir-view processing.

Invalid SST value: The value written to a target pixel when the pixel is excluded from the ROI or the SST calculation yields an invalid result.

##### Button Group

Run Creates the target product. The SST processing is actually deferred until its band data are accessed, either by writing the product to a file or by viewing its band data. When the Save as option is checked, the SST processing is triggered automatically.

Close Closes the dialog.

##### Menu Group

File The entries found in this menu allow to save the current processing parameters to disk and to open a saved parameter set from disk.
