Evolution of SST and XCO 2 in the summer ice free Arctic Ocean: is IASI able to contribute to climate change studies?
International audience The Arctic Ocean is a very important region of the globe in which the effect of climate change can bedetected over short time periods. We have used the possibility provided by the two infrared soundersIASI-A and IASI-B on the MetOp platforms to retrieve the sea surface tempera...
