the downward movement of surface waters caused by the convergence of water masses or by waters meeting a coastline.

Although ominous-looking in visible light (8), the 7,500-km-wide blemish appears bright at thermal-infrared wavelengths (9) - an indication that downwelling air has created a clearing in the stratospheric cloud deck, allowing heat to radiate out to space from deeper levels.

When the value of incoming irradiance just below the water surface, [E.sub.d,PAR](z = -0), is known in addition to [K.sub.d,PAR], the downwelling underwater irradiance at depth z, [E.sub.d,PAR] (z), can also be calculated.
