We have presented and developed new theoretic-empirical models of the extinction coefficients of the molecular scattering in the lower. close to the ground troposphere. We have included the indicatrices of backscattering. The models have been presented using general analytical functions valid for the whole wavelength interval 300-1100 nm and for the whole interval of visibility from 0. https://balboasurfandsstylers.shop/product-category/womens-hat/
