The Processor for Aerosol Retrieval and Atmospheric Correction is the second of three main modules within the MERIS/(A)ATSR Synergy toolbox. Its purpose is to derive aerosol optical depths over land and/or ocean and (optionally) provide an atmospheric correction by using the derived AODs. The processor also makes use of quantities derived from the cloud screening module. Therefore, the input for the aerosol retrieval must be an output product from the cloud screening.

The user interface for the Processor for Aerosol and Atmospheric Correction is represented by one main dialog, which consists of the following components:

Figure 6.1. Aerosol Retrieval and Atmospheric Correction: I/O Parameters Tab Pane

This tab pane consists of the following components:

• 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. The source product must be a colocated MERIS/AATSR product which was generated by the Preprocessor module of the MERIS/(A)ATSR Synergy Toolbox AND filled with cloud flags from the Cloud Screening module.
• 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.
