             abstract = "Remote sensing applications play an important role to increase the 
                         monitoring capabilities of inland waters. However, most 
                         applications depend on the sensors resolution fitting the scale of 
                         the phenomena under study. Recently, Cubesats have become an 
                         alternative data source for studies that requires high spatial and 
                         temporal resolutions. However, the radiometric quality of those 
                         data were never evaluated for inland water studies. This research 
                         letter presents the experimental results carried out to assess the 
                         performance of the Remote Sensing Reflectance (Rrs) from 
                         commercial PlanetScope (PS) CubeSat constellation. The radiometric 
                         assessment was performed using 37 field stations on distinct lakes 
                         across Lower Amazon Floodplain. In turbid lakes, PS bands 
                         presented Rrs accuracy metrics sounder than 46% for all VNIR bands 
                         (Rē = 0.56), while the results were not satisfactory (Rē = 0.08) 
                         in clear water lakes. Furthermore, results showed a spectral 
                         dependence in the quality of Rrs retrievals for the turbid lakes, 
                         with sounder metrics in visible bands (red band: MAPE = 37% and Rē 
                         = 0.83). Poor results for Rrs retrieval in low turbidity waters 
                         are explained by both, the low SNR of PS sensor and residual 
                         effect of glint. Finally, there is a high correlation between 
                         water quality parameters (sediments concentration and Secchi 
                         Depth) and PS Rrs at the red band (Rē > 0.74). Although PS images 
                         are mostly designed for land applications, the results suggest 
                         that the radiometric quality is sufficient for the monitoring of 
                         fine-scale mixing processes between river water and floodplain 
                         lakes.",
