Within the CESBIO laboratory, the incumbent will be in charge of a research study on the use of machine learning methods to improve the consideration of aerosol types in the MAJA atmospheric correction chain. The aim is to explore single and multi-variable regression approaches in order to select the most efficient one, which is the result of a compromise between simplicity and speed, accuracy and robustness. The long-term objective is to implement this method in the MAJA chain, which is notably used at CNES in the operational processing of Sentinel-2 data distributed to the community, but also to prepare the use of the chain for the future TRISHNA space mission.


The work required will consist in :
- getting to grips with the radiative transfer calculation tools and learning libraries
- developing methods and tools for generating the training set in an HPC environment
- coding and evaluate the performance of the different learning methods;
- contributing to the implementation and validation of the prototype of the selected algorithm in the MAJA chain.


The incumbent should have a strong background in computer science and mathematics, with some knowledge of data science if possible. A good knowledge of Python is essential, and a good knowledge of learning method libraries (Pytorch, scikit-learn, xarray, Pandas) would be appreciated.
Team spirit
Good knowledge of English

Work Context

The Centre d'Études Spatiales de la Biosphère (CESBIO) is a public research laboratory at the forefront of the field of space remote sensing. The laboratory has nevertheless maintained a human scale with a staff of around 100 people who contribute to the development of themes as varied as ecology, water resource management and agronomy using data from Earth observation satellites.
