The primary objective is to continue to use innovative signal-processing methodologies to extract tropical cyclone (TC) structure information, including genesis likelihood from clouds clusters, intensity information, and wind field structure information from remote-sensing platforms in oceanic regions where in situ observations are sparse. This information is used to develop objective, accurate...

A biofuel from any biodegradable formation process such as a food waste bio-digester plant is a mixture of several gases such as methane (CH4), carbon dioxide (CO2), hydrogen sulfide (H2S), ammonia (NH3) and impurities like water and dust particles. The results are reported of a parametric study of the process of separation of methane, which is the most important gas in the mixture and usable a...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract It is well known that the storm tracks are a preferred region of stratosphere–troposphere exchange (STE), but a systematic and climatological investigation of the connection between cyclones and STE has not yet been p...

today, extra tropical cyclones are recognized not only for the important influence they exert on midlatitude weather conditions but also for their integral role in the earth’s climate system. (gary luckmann, 2012). extra tropical cyclones are fundamental meteorological features and play a key role in a broad range of weather phenomena. they are a central component maintaining the global atmosph...

The overall hypothesis of this research is that the use of passive samplers is an effective method to measure spatial and seasonal trends of atmospheric PCBs in an urban environment. In support of this, I extracted, analyzed and quantified congener specific concentrations from over 200 passive samples and over 200 active sampler, or Hi-Vols. I studied best practices for the use of methods to de...

Markov chain Monte Carlo (MCMC) is an important computational technique for generating samples from non-standard probability distributions. A major challenge in the design of practical MCMC samplers is to achieve efficient convergence and mixing properties. One way to accelerate convergence and mixing is to adapt the proposal distribution in light of previously sampled points, thus increasing t...

The National Ambient Air Quality Standards (NAAQS) for PM in terms of PM10 are ambient air concentration limits set by the EPA that should not be exceeded. Further, some state air pollution regulatory agencies (SAPRAs) utilize the NAAQS to regulate criteria pollutants emitted by industries by applying the NAAQS as property-line concentration limits. Prior to and since the inclusion of the PM10 ...
