Livrables

Report or publication on satellite assessment of aviation impact on cirrus (s’ouvre dans une nouvelle fenêtre)

This deliverable describes results from Task 22 Satellite data and model simulations are used to find out whether and how aviation aerosol effects on cirrus cloud microphysics are detectable from space whether there are subsequent effects on bulk macrophysical cloud properties and what the consequences are for their radiative effects

Synthesis publication/white paper on robustness assessment comprising trade-offs in green flight trajectory planning (s’ouvre dans une nouvelle fenêtre)

This deliverable, produced as outcome of Task 4.3, shows how robust decisions (that is, no-regret solutions) can be obtained when information is fraught with uncertainty of various origin. Using such methods it will formulate recommendations for mitigation strategies that are robust.

Report on statistics of instantaneous radiative forcing and meteorological conditions where the strongest contrails appear (s’ouvre dans une nouvelle fenêtre)

This deliverable from Task 21 provides statistics of the instantaneous radiative forcing iRF of persistent contrails that are found in the IAGOS and JULIA data bases Analyses of the meteorological conditions giving rise to particularly large positive iRF will be provided as well

Assessment/synthesis comprising CO2 and non-CO2 effects of present-day aviation and im-plications of uncertainties for the quantification of future warming contributions from the sector (s’ouvre dans une nouvelle fenêtre)

This deliverable, produced by Task 4.1, will provide a new IPCC-type effects diagram (see Fig.1.1 in Part B), with new values for best estimates and new uncertainty estimates. The differences between the old and the new numbers quantify the impact of ACACIA on our scientific understanding.

Synthesis operational solutions envisaged for reducing aviation emissions (s’ouvre dans une nouvelle fenêtre)

This deliverable produced in Task 53 will provide climate change functions which quantify firstorder atmospheric sensitivities updated for the new results on aerosolcloud interaction

Report on the observational climatology of cloud-active aviation aerosol, including ice nucleating abilities of contrail processed INPs (s’ouvre dans une nouvelle fenêtre)

D 1.1 is an outcome of Task 1.1. It describes the aviation aerosol climatology extracted from IAGOS data and first analyses based on these data. It describes in a second part the results from the laboratory measurements on real aircraft soot.

Report on interhemispheric contrasts regarding spatial and temporal distribution of ice cloud properties (in particular, ice crystal number concentration) with focus on the undisturbed background atmosphere (s’ouvre dans une nouvelle fenêtre)

This is a deliverable from Task 2.1 as well. It describes analyses based on the ATom data set. While the majority of IAGOS and JULIA data are from the polluted northern hemisphere (i.e., data with aviation influence), ATom has data from clean areas of the southern hemisphere as well. This allows to compare the situation in polluted versus unpolluted regions of the world.

Synthesis publication/white paper on overall possible reductions of non-CO2 effects towards Paris Agreement temperature goals (s’ouvre dans une nouvelle fenêtre)

The output of task 4.4 will be summarised in deliverable 4.4. It shows the implications of various possible interpretations of the Paris Agreement for mitigation strategies and how the aviation sector can align with the ambitions set out in the Agreement.

Report on the impact of aviation aerosol on cirrus radiative properties as a function of weather conditions and sensitivity to cloud process representation as derived from LES and GCMs (s’ouvre dans une nouvelle fenêtre)

This deliverable describes the outcomes of Task 1.2, i.e. from the regional (cloud-resolving) and global modelling of the impact of aviation-emitted aerosol on the radiative properties of cirrus clouds, which is the basis for assessments of the corresponding radiative forcing. Uncertainties are estimated using sensitivity studies, by mutually comparing results from two cloud-resolving models, by comparing their results from two global models, by using two different emission inventories, by comparison of certain scenes with matching satellite observation data and by exploring different cloud parameterisation settings.

Field Campaign Design White Paper (s’ouvre dans une nouvelle fenêtre)

"The ""Field Campaign White Paper"" is produced by task 3.3. It will provide a synopsis of evidence for aviation induced climate impacts, and will lay the ground for the detailed mission design and strategies."

Synthesis report on dissemination and wider distribution, lesson learnt (s’ouvre dans une nouvelle fenêtre)

This deliverable, which is not associated to any special task in WP 5, serves as an instrument to monitor the success of ACACIAs dissemination and communication activities. It will provide lessons learnt.

Quantification and evaluation of the importance of the aviation aerosol interactions with low-level clouds (s’ouvre dans une nouvelle fenêtre)

This deliverable is the outcome of task 1.3. The impact of aviation-emitted aerosol on low-level clouds is potentially very large, but the uncertainty of this effect is particularly large as well. The deliverable will describe new modelling results using an updated aerosol dynamics scheme. Second, the paths over which the cruise-emitted aerosol is transported to low level clouds will be shown and it will be quantified which fraction of the aerosol impact on low-level clouds can be attributed to cruise-level flights and which to aircraft operations near airports (LTO cycle).

Report on spatio-temporal patterns of occurrence probabilities and properties of contrails and contrail cirrus including atmospheric conditions favourable for their formation (s’ouvre dans une nouvelle fenêtre)

This deliverable from Task 2.1 takes the IAGOS, JULIA, and ATom data bases to characterise situations which give rise to persistent contrails and contrail cirrus.

Summary publication of the main results of ACACIA (s’ouvre dans une nouvelle fenêtre)

This deliverable will be a publication in a scientific journal (Open Access). At the end of the project it will be ready for submission.

Report on interaction between individual effects of aviation emissions (s’ouvre dans une nouvelle fenêtre)

This deliverable is an outcome from Task 24 It describes the results of sensitivity studies with a chemistryclimate model The model is used to find out whether there are interactions and tradeoffs between different aviation effects that is whether improvements for climate in one aspect can incorporate deteriorations for climate in other aspects

Report on favourable atmospheric situations for aviation-induced effects (s’ouvre dans une nouvelle fenêtre)

This deliverable describes the results from Task 32 It will characterise meteorological conditions where aviation emissions have a particularly strong effect on clouds and atmospheric compositions and where such effects can be detected that is where the signaltonoise ratio is sufficiently large

Strategic roadmap and agenda available for scientific assessments, i.e., IPCC, WMO (s’ouvre dans une nouvelle fenêtre)

This deliverable, produced as a service of task 5.1, is to help organisation of the dissemination of scientific results of ACACIA into international assessments (e.g. IPCC). Deadlines for the submission of results and texts will be collected and announced within the consortium.

Report on methodological gaps in addressing the climate effects of aviation by field campaigns (s’ouvre dans une nouvelle fenêtre)

This is a deliverable from Task 3.1. It will collect results from a literature study and provide lessons learned. It is the groundwork for setting up concepts for new measurement campaigns.

Synthesis publication on technological trade-offs and associated climate impact (s’ouvre dans une nouvelle fenêtre)

Deliverable 4.2 describes the results of Task 4.2. It will show the mitigation potential for the future aviation system under various technology pathways. Especially it will demonstrate and clarify trade-offs between various options.
