tropospheric CO2 Jungfraujoch regional pollution events
2011/2/25
A quantum cascade laser based absorption spectrometer (QCLAS) is applied for the first time to perform in situ, continuous and high precision isotope ratio measurements of CO2 in the free troposphere....
Direct satellite observation of lightning-produced NOx
Direct satellite observation lightning-produced NOx
2010/11/30
In this study we present a systematic analysis of NO2 column densities from SCIAMACHY measurements over active thunderstorms, as detected by the World-Wide Lightning Location Network (WWLLN), where th...
Observation operator for the assimilation of aerosol type resolving satellite measurements into a chemical transport model
aerosol type satellite measurements a chemical transport model
2010/11/29
Modelling of aerosol particles with chemical transport models is still based mainly on static emission databases while episodic emissions cannot be treated sufficiently. To overcome this situation, a ...
Tomographic retrieval of cloud liquid water fields from a single scanning microwave radiometer aboard a moving platform – Part 2: Observation system simulation experiments
cloud liquid water fields a single scanning microwave radiometer a moving platform Observation system simulation experiments
2010/8/16
Part 1 of this research concluded that many conditions of the 2003 Wakasa Bay experiment were not optimal for the purpose of tomographic retrieval. Part 2 (this paper) then aims to find possible impro...
Measurements of volatile organic compounds in the middle of Central East China during Mount Tai Experiment 2006 (MTX2006): observation of regional background and impact of biomass burning
volatile organic compounds middle of Central East China Mount Tai
2010/2/21
The measurement of volatile organic compounds (VOCs) was carried out at the summit of Mount Tai, located in the center of the Central East China (CEC) region, in June 2006 as part of the Mount Tai Exp...
Observation of nitrate coatings on atmospheric mineral dust particles
nitrate coatings atmospheric mineral dust particles
2009/3/31
Nitrate compounds have received much attention because of their ability to alter the hygroscopic properties and cloud condensation nuclei (CCN) activity of mineral dust particles in the atmosphere. Ho...
Modelled radiative forcing of the direct aerosol effect with multi-observation evaluation
Modelled radiative forcing direct aerosol effect multi-observation evaluation
2009/3/13
A high-resolution global aerosol model (Oslo CTM2) driven by meteorological data and allowing a comparison with a variety of aerosol observations is used to simulate radiative forcing (RF) of the dire...
Methane plume over south Asia during the monsoon season: satellite observation and model simulation
Methane plume south Asia monsoon season
2009/3/13
Satellite retrievals of methane (CH4) using the Atmospheric Infrared Sounder (AIRS) on the EOS/Aqua platform from 2003–2007 show a strong, plume-like enhancement of CH4 in the middle to upper troposph...
Rayleigh lidar observation of a warm stratopause over a tropical site, Gadanki（13.5° N; 79.2° E）
Rayleigh lidar warm stratopause tropical site
2009/3/6
The first Rayleigh lidar observation of a stratopause warming over a tropical site, Gadanki (13.5° N; 79.2° E), is presented in this paper. The warming event was observed on 22-23 February 2001, and f...
