摘要

This paper presents the first measurements of total ozone amount performed at the radiometricstation of Badajoz (Spain) by means of a multichannel radiometer GUV‐2511. The retrieval of totalozone amount from GUV measurements of solar ultraviolet irradiance is performed with the supportof look‐up tables calculated using the SBDART radiation transfer code. This methodology is based onthe different absorption by ozone suffered by the radiation at two certain near wavelengths. In thiscase the pair 305, 340 nm was chosen because of its better performance than the pair 305, 320 nm.The look‐up table contains the ratio between irradiances at the mentioned wavelengths calculatedunder different theoretical conditions of solar zenith angle and total ozone amount. The estimationsof actual total ozone amount are calculated applying the look‐up table to the experimental irradianceratios as measured by the GUV radiometer. In order to validate these estimations, they are comparedwith the values provided by the OMI (Ozone Monitoring Instrument) aboard NASA EOS/Aurasatellite during April 2010. Results indicate a general good agreement between both datasets,showing a notable dependence with the cloudiness conditions.
