Data Service
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.
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.
FMI's GOMOS & OSIRIS L3 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).
GOMOS HRTP (high-resolution temperature profiles)
The high-resolution temperature profiles are retrieved from the GOMOS night-time occultations using the FMI Scientific Processor (FSP v1.0).
GOMOS (Global Ozone Monitoring by Occultation of Stars) operated on board the Envisat satellite in 2002-2012. HRTP is retrieved using bi-chromatic
stellar scintillation measurements by the GOMOS fast photometers. The HRTP profiles are retrieved with very good vertical resolution ~200 m and high
accuracy ~1-3 K for altitudes 15-32 km and a global coverage.
METEOR (MEsospheric TEmperature and Ozone climate data Record)
METEOR is an ESA funded Science for Society project which aims to generate long data records of Mesospheric temperature and ozone.
