[en] Ile de La Réunion is a complementary site in the Network for the Detection of Atmospheric Composition Change (NDACC), situated in the southern tropics, at 21°S, 55°E. In support of a better understanding of atmospheric chemistry and physics above tropical regions, we have implemented new ground-based MAX-DOAS (multi-axis DOAS) and FTIR (Fourier transform infrared) observations at this site, on a campaign basis since 2002. At present, we have data from 2002 (month of October), 2004 (August to October) and 2007 (end of May until the end of October). Additional campaigns are planned until the availability of a new infrastructure for permanent observations at the Maido (~ 2000 masl), around 2010.
Here, we report on the available time series for a number of tropospheric species (CO, H2CO and CH4,) and stratospheric halogen species, comparisons between MAX-DOAS and FTIR data of H2CO, and comparisons of ground-based and satellite data.
