Hi,
Does anyone know how to convert radiant count (e.g. data from seawifs level 1) to Es and Lt? I think they are linearly related.

You can run SeaDAS and output Lt and Es to the Level-2 file.

The relationship between counts and fully calibrated radiances is not a simple one. See background and references listed here:

Es requires knowledge of solar path transmittance through the atmosphere.
