Variation of Ozone in the Pantanal Environment Based on Probability Distributions

ABSTRACT The tropospheric ozone column (O3) plays a fundamental role in terrestrial life, particularly in climate variability, and protects the terrestrial biosphere from ultraviolet (UV) radiation. The study investigates the variation of the O3 concentration column in the Pantanal based on probability distributions. The adequacy of the Log Normal (LN), GUM (Gumbel) and GEV (Generalized Extreme Values) distributions were tested using the Kolmogorov-Smirnov (KS), D (Anderson-Darling), AIC (Akaike Information Criterion), BIC (Bayesian Information Criterion), R2(coefficient of determination) and RMSE (root mean square error) tests in the period from 2005 to 2020. In most months investigated, the Pantanal follows the GUM and GEV probability distributions. In addition, monthly means of O3 and standard deviations were calculated. It is worth mentioning the variability of O3 and the impact on climate change.
