Ozone is arguably the most important trace gas in the atmosphere, and improved monitoring of ozone throughout the atmosphere is essential. This Phase 2 project continues the development of a complete, automated system for measuring ozone from on board commercial aircraft. There is already one program within NOAA, CAAMP (Commercial Aircraft Atmospheric Measurement Program), for measuring a variety ...

In our Phase 1 work we were able to replicate and build on recent results at NIST with superconducting transition (SCT) thermometers, which suggested that dramatic improvements may be achieved in detectivity and range of application, of cryogenic electrical substitution radiometers. Cryo-ESR's are widely used as the most accurate absolute standards of radiative flux and irradiance. In Phase 2, we ...

Despite major advances in CFD technology over the past two decades, simulation of industrial spray combustion systems remains challenging due to difficulties in modeling various droplet physical phenomena and in dealing with the geometrical complexity. The proposed study will develop a 3-dimensional code incorporating advanced physical models for droplet transport/vaporization and spray combustion ...

The primary objective of the Phase 1 program was the development of optical fiber devices and cost-effective signal conditioning systems to produce commercially available composite process monitoring systems. The tasks successfully completed during the Phase 1 effort are as follows: (1) examined the performance requirements of the optical fiber devices and demodulation systems for FT-IR- and fluor ...
