A simple technique for the fast retrieval of the total ozone column amount from GOME (Global Ozone Monitoring Experiment) uncalibrated spectra is described in detail. The TIDAS (Temperature Independent Differential Absorption Spectroscopy) technique uses GOME's capability of measuring atmospheric spectra over a broad wavelength range with high spectral resolution. Applying the Beer-Lambert law to two spectral windows where the ozone absorption cross sections show similar temperature dependence retrieves the ozone slant columns. A simple geometric air mass factor is computed for a fixed height spherical atmosphere (SAMF: Simplified atmospheric Air Mass Factor) to retrieve ozone vertical amounts. Vertical ozone values are compared to the GDP (GOME Data Processor), and to ground based Brewer ozone measurements.
