I'm having some trouble grasping the distinction between data levels and actual physical interpretation of data.
Say we are talking about chlorophyll concentration: level 1 would include both radiance L (power of the light radiation at specific wavelength per unit solid angle per unit area) and reflectance R (ratio of specific radiance/iradiance, no need to get specific), while level 2 would be chlorophyll concentration for a given swath obtained by applying the algorithms (contained within l2gen) to the appropriate level 1 data.
Am I understanding this correctly?
Thanks for the reply. I'm aware of the documentatiton, but the term "geophysical" is still too vague to me and doesn't really help me place radiance and/or reflectance into level 1 or 2...

If the algorithm doesn't help, would you like to be referred to other resources? Is there something we can do to improve the existing documentation for you?
As for suggestions, I reckon some tacit examples of data levels in the documentation would be of great use.
Thank you once again!
