Air–sea gas exchange in the North Atlantic: 3He/SF6 experiment during GasEx-98
Tellus: Series B, Chemical and Physical Meteorology, 2016 GasEx-98 was the first open-ocean process study where gas transfer velocity measurements were made with several robust techniques, including airside eddy covariance of CO2 and deliberate injection of 3He and SF6.

Does Airport Regulation Benefit Consumers? [PDF]
Airport regulation is aimed to impose price caps or other schemes on services supplied by airports to airlines that use them. However, it is not clear that regulation benefits the final consumers, the passengers.

No more conflicts: the development of a generic airport model in a sequence-optimization framework [PDF]
, 2016 International audienceComponents of the airport airside such as runways, taxiways and aprons, have a significant impact in the total capacity of the airport system, where capacity is usually considered as maximum number of air traffic movements or number

Sea Ice Modulates Air–Sea Methane Flux in the Southern Ocean
Geophysical Research Letters, Volume 52, Issue 1, 16 January 2025.Abstract The Southern Ocean (SO) is predicted to be a weak sink for atmospheric CH4, although the magnitude is uncertain due to a lack of observations of the marginal ice zone (MIZ). Using both eddy covariance and bulk formula flux measurements from the icebreaker R/V Xuelong2, we found that the eastern SO during an austral summer was a sink for CH4 ...

Prediction of airport surface potential conflict based on GNN‐LSTM
IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.Identify potential conflict hot spots at Shenzhen Bao'an an International Airport based on taxi paths and model the taxiway structure. Use the GNN‐LSTM model to predict the number of potential departure conflicts. Finally, the effectiveness and superiority of the method are verified through comparative experiments. Abstract The development of the civil

Exergy analysis of isochoric and isobaric adiabatic compressed air energy storage
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This paper develops an exergy analysis comparing three adiabatic compressed air energy storage system layouts, operating under isochoric and isobaric modes. Abstract Adiabatic compressed air energy storage (ACAES) is an energy storage technology that has the potential to play an important role in the transition to a predominantly renewables‐driven net ...

Energy Science &Engineering, Volume 12, Issue 10, Page 4070-4089, October 2024.A combined numerical simulation and on‐site monitoring method was used to analyze the asymmetric development characteristics of overlying rock fractures in a goaf under the condition of a goaf side entry formed by roof cutting and to explore the gas accumulation area in the goaf, achieving precise gas extraction from the goaf. The results demonstrate a
