The CHAMP satellite has revealed new observations of the upper F region ionosphere and
the thermosphere. This chapter reviews these new findings at low and equatorial latitude …

Anthropogenic activities have significantly altered atmospheric chemistry and changed the
global mobility of key macronutrients. Here we show that contemporary global patterns in …

Using isentropic trace gas gradients of O3 and CO, the discontinuity in the chemical
composition of the upper troposphere (UT) and lower stratosphere (LS) is examined on …

Oceanic methanol, acetaldehyde, and acetone concentrations were measured during an
Atlantic Meridional Transect (AMT) cruise from the UK to Chile (49° N to 39° S) in 2009 …

Abstract Using the Community Earth System Model (CESM) version 1.2, this study
investigates the changes in secondary inorganic aerosols (SIOAs) over the Northern …

A global climate chemistry model CAM-Chem is driven by the meteorology output from
community climate system model version 3 (CCSM3) to investigate the relative contributions …

The average cost to develop each new pharmaceutical drug is approximately $1 billion or
more and takes 12-15 years from laboratory concept to an approved drug on the shelf at the …

Aerosol modeling is central to both climate projections and air quality forecasts. In climate
modeling, the total estimated aerosol radiative forcing uncertainty range (-2 to-0.6 W m-2 in …

The central point of this thesis is the application of middle atmosphere CO as tracer for polar
dynamics and its variability. A time series of vertical CO profiles covering the two winters …

Abstract The Community Multiscale Air Quality (CMAQ) model instrumented with the Direct
Decoupled Method in three dimensions (DDM-3D), an advanced method for sensitivity …
