The current operational multi-band atmospheric correction algorithms implemented by NASA and NOAA for global remote sensing of ocean color from VIIRS (Visible Infrared Imaging Radiometer Suite) data are mostly based on the 2-band version SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) algorithm. These generally use two NIR bands, one centered near 0.75 μm other 0.865 μm, a band ratio method der...

With the increasing interest for Arctic Ocean resources and faced with its sensitivity to climate change, it is important to accurately monitor the chlorophyll-a (Chla) concentration that is a key indicator of phytoplankton biomass and marine productivity. The performances of three operational algorithms (OC4v6, OC3Mv6, OC4Mev6), two Arctic adapted algorithms (OC4L, OC4P), and one semi-analytic...

The availability of a nearly-continuous record of remotely-sensed chlorophyll a data (chl a) from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission, now longer than ten years, enables examination of time-series trends for multiple global locations. Innovative data analysis technology available on the World Wide Web facilitates such analyses. In coastal regions influenced by river outf...

The impact of natural and anthropogenic sources of a ir pollution has gained increasing attention from scientific communities in recent years. Indeed , tropospheric aerosols not only perturb rad iative energy balance by interacting with solar and terrestrial rad iation, but also by changing cloud properties and lifetime. Furthermore, these anthropogenic and natural air pollutants, once generate...
