Bacterial cell counting can be determined by optical density at 600 nm, which indicates the growth phase for harvesting the cells.

Andrew Daley, a physicist at the University of Innsbruck in Austria, and his colleagues provoked this bond by pumping an ultracool, high - density collection of rubidium atoms — known as a Bose - Einstein condensate — into a 3 - D «cage» of laser light, known as an optical lattice.

The optical density was detected at 550 nm using an enzyme - linked immunosorbent assay plate reader (BIO-TEK, Winooski, VT).

I am continually amazed at the lack of discussion of obvious things, like the growing optical density of the global nitrous oxide haze, and the tendency of jet contrails to bloom into clouds, that visibly reduce the light energy arriving at the Earth's surface.

The first point I'm trying to make is that, in my opinion, if what we are talking about is the wavelength (s) absorbed by CO2, then where the partial pressure (or optical density) of C02 drops to near - 0 is a lot more interesting than where the sum of all gas partial pressures, where the majority of other gases do not absorb at the wavelength of CO2, drops to near - 0, which is the more traditional meaning for TOA.

Re 423 Chris G — whether the effect saturates at a given density depends on the way the temperature is distributed; if the temperature from TOA downward is isothermal for a sufficient thickness, than the effect could be saturated at TOA (if starting from a large enough optical thickness per unit atmospheric mass path, a change in the density of the gas / etc that contributes optical thickness would then have little to no effect on the flux at TOA, which is what is meant by saturation.

A change in clouds may reflect it or if the optical density of the atmosphere due to water + CO2 (+ everything else) is already saturated at those wavelengths then no additional energy will get added.
