ORA Ozone Profiles

Ozone profiles from 30 to 110 km.

In 1985, it was said:
The instrument ORA is an occultation radiometer, which has been accepted by ESA (European Space Agency) for the first EURECA (European Retrievable Carrier) flight, scheduled in 1988.
EURECA is a European satellite, which will be launched by the shuttle and put into orbit at an altitude of about 500 km (orbit-equator angle :: 28°). After 6 months of flight EURECA wi ll be retrieved and brought back to earth by the Shuttle.

The ORA radiometer will measure the solar radiation as absorbed by the atmosphere during sunrise and sunset, at 10 wavelengths. An inversion of the occultation data should allow the determination of profiles of water vapour, co2, N02, o3 and aerosols in the mesosphere and stratosphere.

EURECA was finally launched in 1992.
