I am interested in studying the atmosphere-biosphere interactions, in particular land and sea surface temperatures and their relationship to atmospheric chemistry and physics.

I. Land and sea surface temperatures retrievals using AI 

Using deep learning techniques, we deliver at LATMOS a clear sky skin temperature (land + sea) product from the IASI  instruments. More information can be found at: https://iasi-ft.eu/products/skt/

 

II. Wet Bulb Temperature (WBT)

III. Atmospheric Composition

I study ozone, carbon monoxide, ammonia, and other species ; their trends and their interaction with meteorology at different altitudes in the atmosphere. For example, the effect of sudden stratospheric warming events on ozone concentration in Antarctica:
