Three Color Particle Optical Extinction Monitor, Phase I

The development of these monitors will allow NASA researchers to routinely measure particle optical extinction levels, a fundamental measurement required for radiation transport calculations in climate change models. These monitors are also highly suitable for the measurement of optical extinction in combustion systems such as aircraft, diesel and gasoline-fueled engines which emit soot. The commercial market for these instruments comprises several thousand researchers in the atmospheric measurements community. These monitors are suitable for use in existing monitoring networks in the United States and Europe. We expect ready acceptance as these monitors will cost less than buying three single wavelength monitors as well as taking up much less space. There is also a market for these monitors involving the measurement of aircraft engine soot emissions. More »
