First-of-its-kind fluorescence map offers a new view of the world's land plants
Date:6/6/2011

phasized.

More work needs to be done, for example, to understand how plant fluorescence varies depending on light conditions. In strong afternoon light, the conditions that GOSAT made its observations, unstressed plants produce a stronger fluorescence signal than stressed plants. However, complicating matters, the reverse is true in the morning or evening when light is less intense.

To disentangle the two opposing effects, the Goddard-based group plans to continue refining the mathematical methods they used to calculate fluorescence. Meanwhile, groups of scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif. -- as well as Japanese and European research groups -- are in the process of honing similar fluorescence-monitoring methods.
