Estimated error budget in the O3 retrievals. The error estimations are performed for the O3 retrievals from the measured spectra in a the dry season (shown in Fig. 4a) and in b the wet season (on June 25, 2005). The error elements consist of model parameters (atmospheric temperature, scaling factor, and tropospheric opacity) and noise errors. The total error is given by the square root of the diagonal elements of the error covariance matrix
