Mediterranean and Black Seas: Photosynthetically Active Radiation (PAR) levels 1998-2003 (monthly)

Photosynthetically Active Radiation (PAR) reaching the Mediterranean/Black Sea ocean surface.
PAR is a SeaWiFS product and it is defined as the quantum energy flux from the Sun in the
spectral range 400-700 nm (SeaWiFS PAR Algorithm Documentation).
The graph below shows the max/mean/std monthly levels of PAR in the Mediterranean basin.
