PLAM – a meteorological pollution index for air quality and its applications in fog-haze forecasts in North China [PDF]

Atmospheric Chemistry and Physics, 2016
Using surface meteorological observation and high-resolution emission data, this paper discusses the application of the PLAM/h index (Parameter Linking Air-quality to Meteorological conditions/haze) in the prediction of large-scale low visibility and ...

Chemical Composition of the Atmosphere

, 2012
Atmospheric trace gases have an important impact on Earth’s radiative budget, the oxidative or cleansing ability of the atmosphere, the formation, growth and properties of aerosols, air quality, and human health. During recent years, the coupling between atmospheric chemistry and climate has received particular attention.

PREDICTIONS OF THE ATMOSPHERIC COMPOSITION OF GJ 1132b [PDF]

The Astrophysical Journal, 2016
ABSTRACT GJ 1132b is a nearby Earth-sized exoplanet transiting an M dwarf, and is among the most highly characterizable small exoplanets currently known. In this paper, we study the interaction of a magma ocean with a water-rich atmosphere on GJ 1132b and determine that it must have begun with more than 5 wt% initial water in order to ...
