| Résumé : | Skin temperature Tskin, depend on the interactions and energy fluxes exchanged between the surface and the atmosphere, and is therefore an important factor for studying Earth’s energy balance, convection at the surface and in the boundary layer, and in attributing the fingerprint of anthropogenic climate change. As part of the IASI-Flux and Temperature ERC project, we evaluate in this presentation a dedicated neural-network IASI Tskin product developed under the framework of this project. We show the extent of which Tskin from thermal infrared sensors, such as IASI, can be used to monitor extreme events in the past decade. This includes pollution episodes, land-use change and urban heat islands, fires, volcanoes, and hurricanes, among other examples. We show the record temperature at each point of the globe, and the date of when this record was attained since IASI’s launch, which reflects the eminent climate change fingerprint in the past few years. This work shows that Tskin can be a valuable parameter in extreme events forecast and analysis. |
