Abstract:
A method for retrieving three most informative meteorological parameters (air mass type, meteorological visibility range, total precipitable water vapor) has been developed based on shipboard hyperspectral measurements of surface downwelling irradiance in the Barents and Kara seas (95-th and 96-th cruises of the R/V ‘Akademik Mstislav Keldysh’, June – August 2024) using the model of (Gregg and Carder, 1990) under cloudless atmospheric conditions. The model parameters are adjusted by solving an inverse problem through minimization of the differences between measured and modeled spectra. The proposed approach expands the potential of using shipborne spectroradiometric data for studying the atmosphere over the ocean and can serve as a basis for validating satellite products and reanalysis data characterizing the state of the cloudless atmosphere.
