New tropospheric satellite products are becoming available, that are of large interest for tropospheric chemistry, climate change and air quality studies provided that they are of high enough quality. An example here of are the CO and CH4 products retrieved from SCIAMACHY near-infrared observations.

This contribution proposes the use of ground based FTIR measurements, taken from the NDSC global network, for the validation of tropospheric satellite data such as the SCIAMACHY CO and CH4 data, and IASI chemistry products in the near future. It will evaluate the capabilities of the satellite data to reproduce the temporal and latitudinal variations of the CO and CH4 fields, on a quasi-global scale. An assessment of the accuracy of the data will also be made.

The main deliverables to ACCENT will be scientific presentations and reports.
