IASI satellite observation of pollutants over China during 10 years

Abstract : IASI has been monitoring the atmospheric composition for more than ten years onboard the MetOp-A and MetOp-B satellites. Over China, top-down measurements of carbon monoxide (CO), ozone (O₃), sulfur dioxide (SO₂), ammonia (NH₃) and formic acid (HCOOH) concentrations is now possible using the IASI mission. Some of these products are already distributed operationally by Eumetsat (O3MSAF framework), and others will follow soon. From the atmospheric spectra recorded by the instrument, enhanced levels of pollutants can be detected and followed over China. This talk will present the findings for an extended time period (2008-2016), and review the IASI capability to observe local and regional pollution events, as well as seasonal variations due to the monsoon and other dynamic patterns. Progresses and current limitations to derive long term trends will also be discussed.
