Looking for the instructions on how to download
- subset of level 2 MERIS data
- ship track as vector file (Ferrybox Cosyna)?
Meris data can be found here:
https://earth.esa.int/web/guest/data-access/browse-data-products?p_auth=FEXU7Dou&p_p_id=datasetlist_WAR_ospportlet&p_p_lifecycle=1&p_p_state=normal&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_datasetlist_WAR_ospportlet_resetCur=true
Just filter for the MERIS instrument.
And for COSYNA data you might have a look here:
