As some of you remember from the Spring Survey Cruise,\n I was trying to get the PI's to use percent light level depths based\n on downwelling vector irradiance at 488 nm, instead of the PAR\n values. All near-surface downwelling optical measure- ments are noisy\n and it is difficult to extrapolate to the surface. One method which\n helps in fitting this data near the surface is to plot it in log space\n and for many wavelengths the irradiance is linear. Downwelling\n irradiance at 488nm has this near-surface attribute. Unfortunately, a\n PAR profile is curved near the surface (enhanced attenuation in the\n red). making extrapolation difficult and introducing errors in\n estimating light depths. Quoting Gordon and McCluney (1975, Appl.\n Opt. 14,2) \"Furthermore, for broadband sensing systems, z90 can be\n determined only from spectral irradiance measurements..\". z90 is the\n depth at which 90% of the diffusely reflected irradiance originates\n that a satellite can observe, which is also the 37% light level.
