International Journal of Applied Earth Observations and GeoinformationWe describe our work to improve the cloud masking for satellite ocean color data processing over extremely turbid waters and intensive algae blooms (or floating algae), which are often identified as cloud mistakenly. An improved cloud masking approach is

The hidden influence of large particles on ocean colour
Scientific Reports, 2021 Optical constituents in the ocean are often categorized as water, phytoplankton, sediments and dissolved matter. However, the optical properties of seawater are influenced, to some degree, by scattering and absorption by all particles in the water column.

Simulation of Future Geostationary Ocean Color Images
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2012 The objective of this work is to simulate global images that would be provided by a theoretical ocean color sensor on a geostationary orbit at longitude 0, in order to assess the range of radiance value data reaching the sensor throughout the day for 20 spectral bands similar to those of the Ocean and Land Color Imager (OLCI).

Restoration of missing ocean color data in high-latitude oceans using neural network model
Big Earth DataSatellite ocean color remote sensing plays a crucial role in monitoring marine environment at both regional and global scales. However, due to the reduced accuracy of atmospheric correction models under large solar zenith angles (≥70°), publicly ...
