A worldwide network of radionuclide monitoring stations has been established to monitor radioactive fall-out from nuclear tests. These stations sample the air for radioactive particulates and Xenon on a daily basis. This project is to develop a softwaresystem to determine the location, timing, and yield of nuclear events and their corresponding estimation probabilities using the sampled data from ...

This Small Business Innovation Research (SBIR) Phase I project proposes to adressss the critical need for improved measurements of individual organic compounds in aerosol particles. Aerosols are crucially important due to their effects in global climate and human health, as well to industrial applications such as pharmaceutical drug delivery. This project seeks to develop a new Aerosol Collector M ...

AFRL/VSSS is the lead Air Force group providing the DoD community with physics-based predictive models critical to assessing the utility of EO/IR spectro-polarimetric sensing for aerospace reconnaissance and target cueing. AFRL/VSSS is presently upgrading the government-standard MODTRAN atmospheric radiance code to properly handle polarization. However, there is currently no means of deducing th ...

This project will design and deliver a high accuracy monitor for the photo-chemically coupled pollutants nitric oxide, nitrogen dioxide and ozone using infrared absorption spectroscopy with quantum cascade (QC) lasers. The target molecules are monitored at air quality stations worldwide using instruments which require frequent calibration and are subject to significant chemical interferences (in t ...

Aerosol particles play an important role in visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their impacts which depend on their chemical composition and atmospheric transformations. An innovativeaerosol mass spectrometer has been recently designed to fill a critical need for size-resolved, quantitative chemical composition data on aerosol ...

DESCRIPTION (provided by applicant): The Quartz Crystal Microbalance (QCM) is a well-established technology for quantifying small changes in mass. The long-term objective of this program is to improve the QCM so that it is suitable for use as a field test for the common, foodborne bacteria. To do this, we will modify the standard quartz crystal (QC) used in the QCM so as to increase its background ...

Detection and identification of biological agents are challenging tasks, requiring the assessment of a variety of sophisticated analysis techniques. This proposal addresses what is agreed to be the most dangerous threat, agent delivery in aerosol form.Our goal is to develop a field-portable laser diagnostic instrument capable of analyzing a large fraction of the total particles in a sample flow. ...
