The Atmospheric Look-up table Generator (ALG) toolbox is a standalone software package that can be used independently of ARTMO. ALG allows generating and analyzing look-up tables based on a suite of atmospheric RTMs, facilitating consistent and intuitive user interaction, thereby streamlining model setup, running and storing RTM data for any spectral configuration in the optical domain. Principally, ALG allows users to: Configure and run atmospheric RTMs in an intuitive way through a single graphical user interface with input options to insert single values or value ranges. This includes the definition of multiple combinations of key input atmospheric (e.g., aerosol-related, gas concentration profiles, clouds) and geometric (e.g., sensor height, surface height, illumination/viewing angles) variables. Couple atmospheric RTMs with the OPAC aerosol database. Set the spectral range and resolution of the output RTM data at non-contiguous spectral intervals. Run efficiently parallel executions of multiple instances of an atmospheric RTM as a third-party software. Note: ALG toolbox does not provide the compiled nor the source-code of the atmospheric RTM third-party software. Process and store a massive quantity of spectral output data based on a look-up table (LUT) approach in a relational database.
