[1] Ozone is an air quality problem today for much of the world’s population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the clean-air baseline levels of ozone upon which pollution builds. The IPCC 2001 assessment studied a range of global emission scenarios(More)
In a living cell, the antiparallel double-stranded helix of DNA is a dynamically changing structure. The structure relates to interactions between and within the DNA strands, and the array of other macromolecules that constitutes functional chromatin. It is only through its changing conformations that DNA can organize and structure a large number of(More)
[1] Two closely related chemical transport models (CTMs) employing the same highresolution meteorological data ( 180 km 180 km 600 m) from the European Centre for Medium-Range Weather Forecasts are used to simulate the ozone total column and tropospheric distribution over the western Pacific region that was explored by the NASA Transport and Chemical(More)
[1] The spatial and temporal variation in ozone production over major source regions in East Asia during the NASATransport and Chemical Evolution over the Pacific (TRACE-P) measurement campaign in spring 2001 is assessed using a global chemical transport model. There is a strong latitudinal gradient in ozone production in springtime, driven by regional(More)
[1] Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison (‘‘OxComp’’) was conducted for the IPCC Third Assessment Report (IPCC-TAR). OxComp estimated tropospheric changes in ozone and other oxidants during the 21st century based on the(More)
A global three-dimensional chemical transport model (CTM) is used to model the yearly cycle of sea salt.<lb>Sea salt particles are produced by wind acting on the sea surface, and they are removed by wet and dry deposition.<lb>In this study, forecast meteorological data are taken from the ECMWF. The modeled concentrations are compared<lb>to measured(More)
