We present in this study both measurement-based and modeling analyses for elucidation of source attribution, influence areas, and process budget of reactive nitrogen oxides at two rural southeast United States sites (Great Smoky Mountains national park (GRSM) and Mammoth Cave national park (MACA)). Availability of nitrogen oxides is considered as the limiting factor to ozone production in these...

Moist tropical (MT) air masses routinely host convective precipitation, including weakly forced thunderstorms (WFTs). These short-lived, isolated events present recurring forecasting challenges due to their spatially small footprints and seemingly erratic behavior in quiescent warm-season environments worldwide. In particular, activity is difficult accurately characterize via probability of pre...

Measurements of the submicron fraction of the atmospheric aerosol in the marine boundary layer were performed from January to March 2007 (Southern Hemisphere summer) onboard the French research vessel Marion Dufresne in the Southern Atlantic and Indian Ocean (20 S–60 S, 70 W–60 E). We used an Aerodyne HighResolution-Time-of-Flight AMS to characterize the chemical composition and to measure spec...

Relic neutrino νr light masses clustering in Galactic and Local Hot Dark Halos act as a beam dump calorimeter. Ultra High Energy ν, above ZeV, born by AGNs,GRBs at cosmic edges, overcoming the Greisen, Zatsepin, Kuzmin (GZK) cut-off, may hit near Z resonance and WW-ZZ channels energies: their showering into nucleons and γ Ultra High Cosmic Ray (UHECR) fit observed data. Any tiny neutrino mass s...

We explored the seasonal characteristics in wet deposition chemistry for two sites located at different elevations along the east slope of the Colorado Front Range in Rocky Mountain National Park. Seasonally separated precipitation was stratified into highly concentrated (high salt), dilute (low salt), or acid-dominated precipitation groups. These groups and unstratified precipitation data were...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...
