Abstract

This research reconstructed and validated the broadband UVA irradiances derived from discrete spectral irradiance data retrieved from the Ozone Monitoring Instrument (OMI) satellite from 1 January to 31 December 2009. OMI data at solar noon was compared to ground based spectral irradiances at Toowoomba (27°36’ S 151°55’ E), Australia at 310, 324 and 380 nm for both cloud free and all sky conditions. There was a strong relationship between the ground based UV spectroradiometer data and satellite based measurements with an R2 of 0.89 or better in each waveband for cloud free days. The data show an over-estimate of the satellite derived spectral irradiances compared to the ground based data. The models developed for the sub-tropical site data account for this over-estimation and are essential for any data correlation between satellite and ground based measurements. Additionally, this research has compared solar noon broadband UVA irradiances evaluated with a model and the discrete satellite spectral irradiances for the solar noon values of cloud free days to those measured with a ground based UVA radiometer. An R2 of 0.86 was obtained confirming that for cloud free days the broadband UVA can be evaluated from the OMI satellite spectral irradiances.
