The BEAM Snow Radiance processor can be invoked from the Visat 'Tools' menu as shown below.
The GUI for the Snow Radiance processor consists of three tab panes
- I/O Parameters
- Target Bands
- Processing Parameters
which will be described below.
The Snow Radiance processor needs as input a MERIS and an (A)ATSR L1b product to derive all the quantities listed in the previous chapter. For the derival of only snow grain size, snow albedo and soot content, an (A)ATSR L1b product is not required.
This tab pane consists of the following components:
- MERIS source product file: Select the source product file by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog. This source product must be a standard MERIS L1b product.
- Checkbox 'Compute snow grain size / pollution only (no AATSR L1b required)': If this checkbox is selected, only snow grain size, snow albedo and soot content will be computed. The text field to select an AATSR L1b product (see below) will be hidden (Figure 4.3).
- AATSR source product file: Select the source product file by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog. This source product must be a standard AATSR L1b product.
- Target product file: Select the target product file by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog.
-
Target product format and target directory:
- 'Save as': If this checkbox is selected, the output product will be saved to disk.
- Target product format: Select one of the available output product formats.
- Select the target product directory by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog.
- 'Open in Visat': If this checkbox is selected, the output product is opened in Visat after successful processing.
From the 'I/O Parameters' tab pane, the following control buttons can be accessed:
- 'Run': If this button is clicked, the processor will start the computations.
- 'Close': If this button is clicked, the 'MERIS/(A)ATSR Synergy Toolbox' dialog is closed.
- 'Help': If this button is clicked, this manual is displayed as online help.
