Detection of optical water quality parameters for eutrophic waters by high resolution remote sensing

TL;DR: The BIODIVERSITY mission as discussed by the authors aims to complement these space missions with better GSD acquisitions (typically 8-10 m) with a 5-day revisit on targeted reference sites with identified and well-located characteristics.

TL;DR: The results showed considerable variations in nearshore (case 2) waters due to interference from yellow substance and suspended sediments, however, in offshore areas (case 1) the measurements showed good correlations as mentioned in this paper.

TL;DR: This study uses Sentinel-3 OLCI data to assess Microcystins risk in 100 large lakes in eastern China, mapping spatial and temporal dynamics from 2016-2021, and finds most lakes pose a high risk, but with manageable frequency for drinking water intakes.

TL;DR: This study develops a remote sensing framework to estimate phycocyanin concentration in inland waters, improving accuracy by 80.4% using optical classification and three candidate algorithms, suitable for various water types and turbidity levels.

TL;DR: In this article, the authors present a textbook for introductory courses in remote sensing, which includes concepts and foundations of remote sensing; elements of photographic systems; introduction to airphoto interpretation; air photo interpretation for terrain evaluation; photogrammetry; radiometric characteristics of aerial photographs; aerial thermography; multispectral scanning and spectral pattern recognition; microwave sensing; and remote sensing from space.

TL;DR: In this article, the concept of remote sensing elements of photogrammetry was introduced. Butterfly, thermal, and hyperspectral sensors were used to interpret multispectral, thermal and hypererspectral images.

TL;DR: Monte Carlo simulations of the transfer of radiation in the ocean are used to compute the apparent optical properties of a flat homogeneous ocean as a function of the inherent optical properties and it is shown that these relations can be used with measurements of the upwelling and downwelling irradiance, the beam attenuation coefficient, and the incident radiance distribution.

TL;DR: In this article, a simple spectral atmospheric radiative transfer model for oceanographic applications is proposed, which is based on spectral extraterrestrial solar u-radiance corrected for earth-sun orbital distance.
