TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This Small Business Innovation Research Phase II project concerns the development of a multi-wavelength monitor that will provide rapid, real-time measurement of the average aerosol absorption coefficient in a parcel of sample air. This monitor will employ Aerodyne's patented Cavity Attenuated Phase Shift (CAPS) technology in order to produce a far simpler, smaller, lower cost alternative to more traditional instruments with no loss in sensitivity or accuracy. A unique property of the proposed instrument is that it requires little or no calibration. The Phase II project entails construction a field-ready prototype and deploying the sensor on various field missions undertaken by Aerodyne's particle measurement research group. Aerosol particles affect the radiative balance of the earth directly, by scattering and absorbing solar and terrestrial radiation, and indirectly, by acting as cloud condensation nuclei. The atmospheric loading of aerosols generated through human activities can exert an influence on the earth's radiation budget comparable in magnitude with greenhouse gases. The uncertainties in the current understanding of aerosol direct and indirect forcing limit the ability to quantify human influences on climate change.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Successful development of a low cost multispectral sensor would allow almost routine measurement of the scattering properties of atmospheric aerosols, something precluded by the cost and complexity of current instrumentation.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Quantification of the light absorbing properties of so-called "black carbon" could be readily achieved and could conceivably lead to the development of a monitor for combustor particulate emissions. Such an instrument would be of immediate benefit in at least two regulatory markets, that of stationary combustors (incinerators, power plants, etc.) and emissions certification for commercial aircraft engines.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
