UV index and UV dose: ozone data data version 2.x	UV radiation monitoring: UV index UV dose
Main data product description page

Operational UV data processing

Input to the operational UV index and UV dose processing is the TEMIS operational assimilated global ozone field derived from satellite instruments, namely the operational processing that started with measurements from the SCIAMACHY instrument (01 July 2002 up to 31 March 2012), followed by the GOME-2A instrument (from 01 April 2012 up to 20 March 2019), the GOME-2B instrument (from 21 March 2019 up to 13 March 2024) and the GOME-2C instrument (from 14 March 2024 onwards).

For the UV index and UV dose processing we use the global ozone field at local solar noon, i.e. at the moment the sun in highest in the sky, interpolated from the initial resolution of 1.5 by 1.0 degrees to the UV grid of 0.25 by 0.25 degrees.

The operational global ozone field data is provided with an error estimate, which is propagated to the UV index and UV dose error estimates.

 

Multi Sensor Re-analysis (MSR-2) UV data processing

In addition we have used the Multi Sensor Re-analysis version 2 (MSR-2) ozone record, i.e. a long-term record derived from ozone measurements by multiple satellites. The MSR-2 dataset starts in January 1960 and so does the TEMIS UV data.

As for operational ozone record mentioned above, the UV index and UV dose processing uses the MSR-2 global ozone field at local solar noon.

The MSR-2 global ozone field data is provided with an error estimate, which is propagated to the UV index and UV dose error estimates.
