Paper Abstract

This study is intended to demonstrate the significant shifts in DOM concentration with space and time within and across inland waters (lakes), which can be acquired by the analysis of DOM concentration using Sentinel-2A imagery. Using a remote sensing method (based on Sentinel-2A data) to evaluate DOM quantity or concentration in freshwater (lakes), optical properties shifts of CDOM of spatial and temporal observations at sites in Västerbotten and Jämtland in Northern Sweden can be understood in terms of the landscape features and hydrological events at those locations. Using Sentinel-2A as a data source for these remote sensing methods can provide an effective approach for estimating CDOM concentrations in water to obtain water quality information regularly, and also could help to accurately estimate the CDOM absorption coefficient (aCDOM ) via Sentinel-2A data of the study area. The estimation of (aCDOM ) by using Sentinel-2A could help to study DOM in inland waters at global scale by using following equation aCDOM(420)=5.13(B2/B3)-2.67 Key words: Dissolved Organic Matter component (DOM), water quality, sentinel -2A
