第34届国际湖沼学大会专题1：碳循环和水库温室气体排放（Carbon cycling and greenhouse gas emissions in reservoirs）
第34届 国际湖沼学大会 专题 碳循环 水库温室 气体排放
2018/1/18
Reservoirs are environmental reactors that receive and process large amounts of carbon from their catchments and from the organic matter flooded during the impoundment process. Part of the ensuing emi...
Methane-eating bacteria in lake deep beneath Antarctic ice sheet may reduce greenhouse gas emissions（图）
Methane-eating bacteria lake deep Antarctic ice sheet reduce greenhouse gas emissions
2017/9/1
An interdisciplinary team of researchers funded by the National Science Foundation (NSF) has concluded that bacteria in a lake 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet may digest m...
Characterisation of the magmatic signature in gas emissions from Turrialba Volcano, Costa Rica
Volcanic gases superposition lava shallow hydrothermal system magma volcanic gases magma
2015/1/6
The equilibrium composition of volcanic gases with their magma is often overprinted by interaction with a shallow hydrothermal system. Identifying the magmatic signature of volcanic gases is critical ...
Atmospheric inverse modeling with known physical bounds: an example from trace gas emissions
Atmospheric inverse modeling physical bounds
2014/12/18
Many inverse problems in the atmospheric sciences involve parameters with known physical constraintsExamples include nonnegativity (e.g., emissions of some urban air pollutants) or upward limits impli...
The discovery of a new form of microbial life that can consume the potent greenhouse gas methane has earned University of Queensland (UQ) researchers a place in the prestigious journal Nature.
Assessment of fossil fuel carbon dioxide and other anthropogenic trace gas emissions from airborne measurements over Sacramento, California in spring 2009
fossil fuel carbon dioxide anthropogenic trace gas airborne measurements Sacramento California
2011/2/24
Direct quantification of fossil fuel CO2 (CO2ff) in atmospheric samples can be used to examine several carbon cycle and air quality questions. We collected in situ CO2, CO, and CH4 measurements and fl...

AGRICULTURE GREEN HOUSE GAS CONVERGED EUROPEAN UNION MEMBER STATES
2014/6/24
Panel unit root tests are used to identify convergence of Green House Gas (GHG) emissions among the agricultural sectors of the European Union 27 member states. Although a clear cut conclusion on the...
Greenhouse gas emissions from Indian rice fields:calibration and upscaling using the DNDC model
Greenhouse gas emissions rice fields calibration upscaling DNDC model
2010/1/12
The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) emissions from Indian rice fields with various ...
Assessment of Greenhouse Gas Emissions from Poultry Enteric Fermentation
Nitrous Oxide Methane Respiration Chamber Enteric Fermentation Emission Factors
2016/4/19
Emissions of nitrous oxide (N2O) and methane (CH4) from poultry enteric fermentation were investigated using a respiration chamber. Birds were placed in a respiration chamber for certain intervals dur...
