About Kd Ocean Colour blue

This online platform uses data from the Copernicus Sentinel-5P satellite and shows the daily Kd Ocean Colour (diffuse attenuation coefficient) at the short blue wavelength range across the globe, as well as monthly, seasonal and yearly averages.

The Kd Ocean Colour map for the short blue wavelength range shown here is measured by the Tropomi instrument on the Sentinel 5 Precursor satellite. The short blue wavelength region ranges from 390-423nm.

About this S5P-PAL map

The maps shown on this site have been based on the latest pre-operational Sentinel-5P Level-2 Kd Ocean Colour products (L2__KD____), available from the S5P-PAL data portal. The readme file of this product can be found here.

The Copernicus Sentinel-5P Kd Ocean Colour measurements were first filtered based on the recommendation in the Product Readme file (only data with a qa_value == 1.0 was used). Then the measurements are mapped on a fixed latitude-longitude grid of 8193 x 16385 pixels. The grid is turned into an EPSG:4326 geotiff file using the appropriate color scale, which is again turned into an EPSG:3857 tile map.

The maps and underlying Level-3 gridded data files were generated by S5P-PAL. The Level-3 data can be downloaded from the S5P-PAL Data Portal, or directly via the download button below the map.
