.. _sent3_atmcor_pixclas: Sentinel 3 atmospheric correction and chlorophyll content ========================================================= This service applies on SENTINEL-3 OLCI level 1B images an atmospheric correction and extract chlorophyll percentage concentration over cloudfree water areas. Inside *Insula Intellect* the user can find the card of the processor .. image:: ../../../images/services_1.png :alt: s3atmosphericcorrection processor Running the processor --------------------- as inputs it requires: * one SEN3 OLCI Level-1B ERF acquisitions: it can be selected from the catalogue directly or from bookmarked and personal folders , * an AOI (Area of Interest) : it can be drown directly or imported .. image:: ../../../images/services_1.png :alt: running s3atmosphericcorrection processor Note: When selecting input data from the EDEN catalogue, the dataset name to use for retrieving the required product is SENTINEL-3. Ensure that the selected area is large enough to cover at least the footprint of a Sentinel-3 product. Additionally, applying a filter on the Product Type can help speed up the search process. Output visualization -------------------- Once the pipeline execution is complete, the user can visualize the output products in the *Monitor* section of *Insula Intellect*. The products are: * the chlorophyll percentage concentration map, in COG format visualizable in Insula Perception * the atmospheric corrected product, in netcdf format .. image:: ../../../images/services_3.png :alt: chlorophyll content map As an example, the processor code is accessible on `github `__ .
