Monitoring Phycocyanin with Landsat 8/Operational Land Imager Orange Contra-Band

The Operational Land Imager (OLI) onboard the Landsat 8 satellite has a panchromatic band (503–676 nm) that been used to compute virtual spectral known as “orange contra-band” (590–635 nm). major application of orange contra-band is monitoring cyanobacteria which usually quantified by measurement concentration phycocyanin (PC) an absorption peak around 620 nm. In this study, we evaluated use approach for estimating PC from in situ proximal hyperspectral data Eagle Creek Reservoir (ECR), Indiana, USA. We first validated empirical relationship computation using panchromatic, red, and green bands ECR. retrieval were not successful when entire dataset (R2 < 0.1) or only concentrations higher than 50 mg/m3 0.24). Better results achieved samples was 1.5 times chlorophyll-a = 0.84). These highlighted need development remote sensing algorithms accurate estimation non-PC dominant waters could be track and/or predict blooms.
