Context

CS Group responsabilities for Study of improvement of radiative transfer codes are as follows:

• Method specification, development, validation, user support

The features are as follows:

• SOS-ABS :
• Management of gaseous absorptions: introduction of the CKD method, optimization of the atmospheric profile
• Introduction of the Maignan BPDF model
• Definition of the aerosol model by multi-mode mixing
• Simplification of use: incorrect keyword warning, possibility of simultaneous processing OSOAA :
• User Tips
• Training during “Ocean Optics XXV” Support for the integration of SOS-ABS in 4A/OP Introductory radiative transfer training
