SESSION: SCIENTIFIC SUPPORTING ELEMENTS

       1. Summary of key barriers limiting the exploitation of TRUTHS data (e.g.) 

• utilising UV-VIS-SWIR for retrievals / in data assimilation
• (F)RTM and uncertainties 
• achieving spectral consistency
• cloud classification and modelling
• atmospheric correction (for surface reflectance)
• solar spectral irradiance modelling and spectral calibration 

The objectives of the facilitated discussions are:

       1. Determine the research areas to foster till 2030 to accelerate products uptake and maximise                   benefits from Day-1

       2. Establish a framework to support the radiative transfer modelling needs by identifying the                         required:

• RTM code development for different communities/needs
• Intercomparison and validation studies

       3. Define validation campaign requirements
