Data Service

The GOMOS products provided are based on ESA L2 GOMOS processing (software version IPF 5.0). L2 processing retrieves O₃, NO₂, NO₃, and aerosol extinction profiles using spectral inversion. Level 3 climatologies are collected using 10 degree altitude grid, 1 km vertical grid and using median values (for details, see Kyrölä et al., 2006).

OMI VFD (Very Fast Delivery)
The OMI very fast delivery pages offer near real time satellite measurements over the Northern Hemisphere. The images come available about 15 min after the satellite overpass. From these pages you will find the latest observations of O₃, SO₂, clouds, UV index, UV daily dose and aerosols as individual and composite images.

AC SAF (Satellite Application Facility for Atmospheric Chemistry Monitoring)
AC SAF produces near real-time (NRT), offline and data record products including total/tropospheric O₃, NO₂, O₃ profiles, UV, CO, SO₂, HCHO, BrO, aerosols, glyoksal, Lambertian equivalent radiance and SIF. The NRT products are disseminated via EUMETCast and the offline as well as data records via a dedicated data facility which is available from the AC SAF WWW site.
