Rise in Southeast Asia forest clearance increasing greenhouse gases
forest clearance greenhouse gases Southeast Asia
2021/8/3
Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly...
Rising greenhouse gases pose continued threat to Arctic ozone layer
ozone loss greenhouse gases climate change
2021/8/4
A new study shows that extremely low winter temperatures high in the atmosphere over the Arctic are becoming more frequent and more extreme because of climate patterns associated with global warming. ...
The Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGAN2.1): an extended and updated framework for modeling biogenic emissions
Model of Emissions Gases and Aerosols Nature version 2.1 an extended and updated framework modeling biogenic emissions
2014/12/10
The Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGAN2.1) is a modeling framework for estimating fluxes of biogenic compounds between terrestrial ecosystems and the atmosphere us...
Mobile MAX-DOAS observations of tropospheric trace gases
Mobile MAX-DOAS observations tropospheric trace gases
2010/2/8
From Multi-Axis- (MAX-) DOAS observations, information on tropospheric trace gases close to the surface and up to the free troposphere can be obtained. Usually MAX-DOAS observations are performed at f...
Chemolithoautotrophic production mediating the cycling of the greenhouse gases N2O and CH4 in an upwelling ecosystem
Chemolithoautotrophic production the greenhouse gases N2O and CH4 an upwelling ecosystem
2010/1/21
The high availability of electron donors occurring in coastal upwelling ecosystems with marked oxyclines favours chemoautotrophy, in turn leading to high N2O and CH4 cycling associated with aerobic NH...
Real-time profiling of organic trace gases in the planetary boundary layer by PTR-MS using a tethered balloon
Real-time profiling organic trace gases planetary boundary layer PTR-MS tethered balloon
2010/2/8
A method for real-time profiling of volatile organic compounds (VOCs) was developed combining the advantages of a tethered balloon as a research platform and of proton transfer reaction mass spectrome...
Airborne multi-axis DOAS measurements of atmospheric trace gases on CARIBIC long-distance flights
Airborne multi-axis DOAS measurements atmospheric trace gases CARIBIC long-distance flights
2010/2/8
A DOAS (Differential Optical Absorption Spectroscopy) instrument was implemented and operated onboard a long-distance passenger aircraft within the framework of the CARIBIC project (Civil Aircraft for...
In-situ measurements of oxygen,carbon monoxide and greenhouse gases from Ochsenkopf tall tower in Germany
In-situ measurements oxygen carbon monoxide greenhouse gases Ochsenkopf tall tower
2010/2/8
We present 2.5 years (from June 2006 to December 2008) of in-situ measurements of CO2, O2, CH4, CO, N2O and SF6 mixing ratios sampled from 23, 90 and 163 m above ground on the Ochsenkopf tower in the ...
The benefit of limb cloud imaging for infrared limb sounding of tropospheric trace gases
limb cloud imaging infrared limb sounding tropospheric trace gases
2010/2/8
Advances in detector technology enable a new generation of infrared limb sounders to measure 2-D images of the atmosphere. A proposed limb cloud imager (LCI) mode will detect clouds with a spatial res...
Evaluation and application of a semi-continuous chemical characterization system for water soluble inorganic PM2.5 and associated precursor gases
Evaluation application semi-continuous chemical characterization system water soluble inorganic PM2.5
2010/2/8
Water soluble inorganic particles components (Cl−, SO42−, NO3−, and NH4+) and concentrations of their associated precursor gases (HCl, SO2, HNO3, NH3) were semi-continuously measured...
