Context

CS Group responsabilities for Trishna flight calibration on instrumented sites are as follows:

• Study, development

The features are as follows:

• Simulation of uncertainty on a large number of atmospheric profiles (water vapor, ozone, temperature)
• Simulation of the Luminance in the TOA by the RTTOV code from 4 to 12 microns
• Analysis of the impact on the observable luminance of uncertainty on profiles
• Trishna sensor application

Project implementation
