GUI_CM tool enhancements

☛ Position: Senior Software Developer
☛ Schedule: Nov. 2020 - March 2021
☛ Client: EUMETSAT
☛ Team size: 2 people

This project mainly aimed at upgrading the graphical user interface (GUI) in IDL (Interactive Data Language) of the GUI_CM tool. That tool is part of the Cal/Val toolset for Level 2 (L2) products from the EPS-SG Visible/Infrared Imager (VII) and it is used at EUMETSAT to tune the detection thresholds of the METimage L2 cloud mask algorithm.

Starting from the initial IDL prototype version provided by EUMETSAT, we worked on many updates/improvements on the GUI_CM software:

• Unification of the input files used by the software,
• Reading of multiple new variables from NetCDF files,
• Building of new RGB images,
• Support for additional test types (ie. restoral tests),
• Support for polygonal Region Of Interest (ROI) construction and usage,
• Support for scene specific test threshold tuning,
• Support to build/save/load Constructed Reference Mask (CRM),
• Imporovements on statistic storage,
• Many updates/improvements on the GUI itselft to improve the user interactions,

• IDL
• Linux/ssh (Remote access to EUMETSAT workstations)
• Python
• NetCDF
• Gitlab
