Atmospheric Radiative Transfer models (RTMs) have become important tools for the analysis and processing of optical Earth observation data, providing meaningful links between radiometry and atmospheric composition for applications, such as aerosol radiative forcing, air quality, and atmospheric correction. However, the complexity of these RTMs limit their use and applicability for the broader scientific community.
ALG's modular architecture.
- 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.
ALG's at input variable window.
The broader scientific community can subsequently use ALG for a wide variety of applications such as: atmospheric correction, cross-comparison of atmospheric RTMs, forward simulation, and sensitivity analysis.
This table provides an overivew of ALG's novelties starting from 23 June 2017.
