An analysis of the collection 5 MODIS over-ocean aerosol optical depth product for its implication in aerosol assimilation
the collection 5 MODIS over-ocean aerosol optical depth product aerosol assimilation
2011/1/20
As an update to our previous use of the collection 4 Moderate Resolution Imaging Spectroradiometer (MODIS) over-ocean aerosol optical depth (AOD) data, we examined ten years of Terra and eight years o...
Measured black carbon deposition on the Sierra Nevada snow pack and implication for snow pack retreat
black carbon deposition the Sierra Nevada snow pack snow pack retreat
2010/8/16
Modeling studies show that the darkening of snow and ice by black carbon deposition is a major factor for the rapid disappearance of arctic sea ice, mountain glaciers and snow packs. This study provid...
Theoretical implication of reversals of the ozone weekend effect systematically observed in Japan
the ozone weekend effect Japan
2010/8/16
Systematic changes of the ozone weekend effect are found over broad areas of Japan. These changes are characterized by (1) spatial reversals from a weekend increase in the vicinity of huge precursor s...
Size distributions of dicarboxylic acids, ketoacids, α-dicarbonyls, sugars, WSOC, OC, EC and inorganic ions in atmospheric particles over Northern Japan: implication for long-range transport of Siberian biomass burning and East Asian polluted aerosols
atmospheric particles Northern Japan Siberian biomass burning and East Asian polluted aerosols
2010/8/13
To better understand the size-segregated chemical composition of aged organic aerosols in the western North Pacific rim, day- and night-time aerosol samples were collected in Sapporo, Japan during sum...
Chemical characterisation of iron in dust and biomass burning aerosols during AMMA-SOP0/DABEX: implication for iron solubility
Chemical characterisation iron dust and biomass burning aerosols AMMA-SOP0/DABEX
2010/8/12
The chemical composition and the soluble fraction were determined in aerosol samples collected during flights of AMMA-SOP0/DABEX campaign, which were conducted in the West African Sahel during dry sea...
Size-resolved aerosol water-soluble ionic compositions in the summer of Beijing: implication of regional secondary formation
aerosol water-soluble ionic compositions regional secondary formation
2010/2/21
To characterize aerosol pollution in Beijing, size-resolved aerosols were collected by MOUDIs during CAREBEIJING-2006 field campaign at Peking University (urban site) and Yufa (upwind rural site). Fin...
Peroxyacetic acid in urban and rural atmosphere: concentration, feedback on PAN-NOx cycle and implication on radical chemistry
Peroxyacetic acid rural atmosphere PAN-NOx cycle radical chemistry
2010/2/1
Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphe...
Tree ring-based February–April temperature reconstruction for Changbai Mountain in Northeast China and its implication for East Asian winter monsoon
February–April temperature Northeast China Changbai Mountain winter monsoon
2009/12/3
Long-term climatic records are scarce in the northeast Asia for understanding the behavior of the East Asian Winter Monsoon. Here we describe a 250-year February–April temperature reconstruction (TCBM...
Climate reconstruction from pollen and δ13C records using inverse vegetation modeling – Implication for past and future climates
Climate reconstruction future climates
2009/12/3
An improved inverse vegetation model has been designed to better specify both temperature and precipitation estimates from vegetation descriptions. It is based on the BIOME4 vegetation model and uses...
Concurrent observations of air pollutants at two sites in the Pearl River Delta and the implication of regional transport
air pollutants Pearl River Delta regional transport
2009/10/9
An intensive field measurement study was conducted simultaneously at a site within the inland Pearl River Delta (PRD) region (WQS) and a site in Hong Kong (TC) between 22 October and 1 December 2007. ...
Pressure broadening in the 2ν3 band of methane and its implication on atmospheric retrievals
methane atmospheric retrievals
2008/11/18
N2-broadened half widths and pressure shifts were obtained for transitions in the 2ν3 methane band. Laboratory measurements recorded at 0.011 cm−1 resolution with a Bruker 120 HR Fouriertransfor...
