| Zusammenfassung |
| The surface ultraviolet (UV) radiation product, version 1.20,
generated operationally in the framework of the Satellite
Application Facility on Ozone and Atmospheric Chemistry Monitoring
(O3M SAF) of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) is described. The product is
based on the total ozone column derived from the measurements of the
second Global Ozone Monitoring Experiment (GOME-2) instrument aboard
EUMETSAT's polar orbiting meteorological operational (Metop)
satellites. Cloud cover is taken into account by retrieving
cloud optical depth from the channel 1 reflectance of the third
Advanced Very High-Resolution Radiometer (AVHRR/3) instrument aboard
both Metop in the morning orbit and Polar Orbiting Environmental Satellites (POES) of the National Oceanic and Atmospheric
Administration (NOAA) in the afternoon orbit. In addition,
more overpasses are used at high latitudes where the
swaths of consecutive orbits overlap. The input satellite data are
received from EUMETSAT's Multicast Distribution System (EUMETCast).
The surface UV product includes daily
maximum dose rates and integrated daily doses with different
biological weighting functions, integrated ultraviolet B (UVB) and ultraviolet A (UVA) radiation,
solar noon UV index and daily maximum photolysis frequencies of
ozone and nitrogen dioxide at the surface level. The quantities are
computed in a 0.5°×0.5° regular
latitude–longitude grid and stored as daily files in the
hierarchical data format (HDF5) within 2 weeks from sensing. The
product files are archived in the O3M SAF distributed archive and
can be ordered via the EUMETSAT Data Centre. |
