Global CO_2 fluxes inferred from surface air-sample measurements and from TCCON retrievals of the CO_2 total column [PDF]
, 2011 We present the first estimate of the global distribution of CO_2 surface fluxes from 14 stations of the Total Carbon Column Observing Network (TCCON). The evaluation of this inversion is based on 1) comparison with the fluxes from a classical inversion ...

Influence of vertical transport on free tropospheric aerosols over the central USA in springtime [PDF]
, 1998 Measurements of the atmospheric aerosol chemical composition during the Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) indicate substantial vertical transport of boundary layer aerosol to the free troposphere over the south-central

, 2002 A contrail (a term introduced for “condensation trail” in 1942 by British pilots) is a visible cloud forming behind aircraft, mainly due to water vapor emissions from the engines. Contrails were first observed behind propeller-driven aircraft in 1915 but form as well from the exhaust of jet engines in cold ambient air (Schumann 1996a).

AGU Advances, Volume 6, Issue 6, December 2025.Abstract The challenge of distinguishing convective anvil cirrus from in situ cirrus has long limited the quantification of their distinct roles in regulating upper‐tropospheric moisture and modulating Earth's energy budget. In this study, we address this ambiguity by introducing a physically constrained classification framework that applies advanced ...

A Tool for Programming Embarrassingly Task Parallel Applications on CoW and NoW
, 2013 Embarrassingly parallel problems can be split in parts that are characterized by a really low (or sometime absent) exchange of information during their computation in parallel.

On the Weather Impact of Contrails: New Insights from Coupled ICON–CoCiP Simulations [PDF]
Atmospheric Chemistry and PhysicsContrail forecasts typically neglect feedbacks with the atmosphere. Here, we couple the Contrail Cirrus Prediction model (CoCiP) with the global Icosahedral Non-hydrostatic (ICON) numerical weather model in a two-way mode accounting for contrail-weather ...

Private Governance Responses to Climate Change: The Case of Global Civil Aviation [PDF]
, 2018 This Article explores how private governance can reduce the climate effects of global civil aviation. The civil aviation sector is a major contributor to climate change, accounting for emissions comparable to a top ten emitting country.

A simple framework for assessing the trade-off between the climate impact of aviation carbon dioxide emissions and contrails for a single flight [PDF]
, 2014 Persistent contrails are an important climate impact of aviation which could potentially be reduced by re-routing aircraft to avoid contrailing; however this generally increases both the flight length and its corresponding CO emissions.

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.Abstract Shallow cumulus cloud fields in subtropical marine trade wind environments, particularly over the tropical Atlantic Ocean, show distinct organizational patterns. Among these, Flower‐type clouds are characterized by expansive stratiform cloud patches surrounded by regions of scattered convection.

Forecasting contrail climate forcing for flight planning and air traffic management applications: the CocipGrid model in pycontrails 0.51.0 [PDF]
Geoscientific Model DevelopmentThe global annual mean contrail climate forcing may exceed that of aviation's cumulative CO2 emissions. As only 2 %–3 % of all flights are likely responsible for 80 % of the global annual contrail energy forcing (EFcontrail), re-routing these flights ...
