A coupled atmospheric chemistry and climate system model was developed using the modal aerosol version of the National Center for Atmospheric Research Community Atmosphere Model (modal-CAM; v3.6.33) and the Max Planck Institute for Chemistry’s Module Efficiently Calculating the Chemistry of the Atmosphere (MECCA; v2.5) to provide enhanced resolution of multiphase processes, particularly those i...

The possible trends for atmospheric carbon monoxide in the next 100 years have been illustrated using a coupled atmospheric chemistry and climate model driven by emissions predicted by a global economic development model. Various model runs with different assumptions regarding emissions or model parameters have been carried out to investigate the impacts of model and emission uncertainties on t...

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...

Atmospheric Chemistry and Physics Discussions 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 The decrease of the concentration of ozone depleting substances (ODS) in the stratosphere over the past decade raises the question to what extent observed changes in strat...

New observations with atmospheric neutrinos from the underground experiments SuperKamiokande, Soudan 2, and MACRO, together with earlier results from Kamiokande and IMB, are reviewed. The most recent observations reconfirm aspects of atmospheric flavor content and of zenith angle distributions which appear anomalous in the context of null oscillations. The anomalous trends, exhibited with high ...

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...
