The CEA has developed the CERES-MITHRA (C-M) application to model the radionuclide atmospheric dispersion in order to evaluate the consequences on human health of radionuclide releases in the environment. This application is used either for crisis management or to perform assessment calculations for regulatory safety documents relative to nuclear facilities. C-M code is a time consuming complex...

[1] An idealized global climate model is used to explore the response of the climate to a wide range of dust radiative properties and dust layer heights. The top-of-the-atmosphere (TOA) shortwave forcing becomes more negative as the broadband shortwave single scattering albedo increases and the broadband shortwave asymmetry parameter decreases, but the sensitivity is highly dependent on the loc...

This work provides a comprehensive view of the process of evaluating regional-scale (~2002000 km) three-dimensional numerical photochemical air quality modeling systems, including meteorological, emissions, and air quality components. We have examined approaches to the evaluation of regional air quality modeling systems, as they are currently used in a variety of applications. From this examina...

Atmospheric rivers (ARs) have, in recent years, been recognized as the cause of the largemajority of major floods in rivers all along the U.S. West Coast and as the source of 30%–50% of all precipitation in the same region. The present study surveys the frequencywith whichARs have played a critical role as a common cause of the end of droughts on the West Coast. This question was based on the o...

Mesoscale transport and dispersion of air pollutants from a few major point sources in the Mississippi Gulf coastal region is calculated using a coupled modeling system consisting of the atmospheric dynamical model WRF and the lagrangian particle model HYSPLIT. The sensitivity of the dispersion model results to the meteorological fields is studied by conducting an ensemble of simulations using ...

Review comments on “How to improve the air quality over mega-cities in China? – Pollution characterization and source analysis in Shanghai before, during, and after the 2010 World Expo” by Huang et al. This manuscript provides an important study on the PM2.5 pollution in Shanghai before, during, and after the 2010 World Expo. The topic is applicable for Atmospheric Chemistry and Physics; howeve...

The early history of the atmospheric neutrino anomaly is closely tied to the growth of grand unified theories. Grand unified theories inspired the experimental search for proton decay which led to large well shielded detectors. The primary background to proton decay was due to atmospheric neutrinos so they were studied in some detail. Neutrino oscillations figured prominently at the first works...
