Are thermal infrared measurements of CO 2 from GOSAT andIASI over the Arctic Ocean in summer able to detect climaticchange?
International audience The Arctic Ocean is a region where the impact of global change is detected on an annual basis by a wide varietyof observations: buoys, research vessels and aircrafts. But the large area involved and the need of frequentsampling make polar orbiting satellites a prime source of...
