Dates:
7-9 October 2015

Venue:
ESRIN & CNR – Tor Vergata, Frascati/Rome, Italy

Theme:
Process-oriented evaluation and analysis of CCMI-1 simulations

Highlight:
A joint session with the AeroCom community will be held at ESRIN on the first day (7 October) to focus on plans for CMIP6 (AerChemMIP).
The CCMI meeting on the following days (8/9 October) will be held at CNR – Tor Vergata.
Note: Shuttle buses will be arranged for easy access from hotels in Frascati to both meeting locations.

Scope:
The CCMI 2015 workshop will focus on process-oriented evaluation and analysis of the CCMI Phase-1 (CCMI-1) troposphere-stratosphere resolving chemistry-climate model (CCM) simulations using new observations and diagnostics. It will also provide a platform for discussions on model development and common issues experienced with CCMI-1 simulations. Parts of the workshop will be devoted to discussing plans for CCMI contributions to TOAR (the Tropospheric Ozone Assessment Report, 2016), the next WMO/UNEP ozone (2018) and IPCC climate assessment (2020), and CMIP6 (2015-2020). More information on CCMI can be found at http://www.met.reading.ac.uk/ccmi/.

Workshop goals:
The goal of the workshop is to bring together modelling groups, experimentalists, and scientists who analyze the data and to provide a platform for discussion of the most recent progress within CCMI.

Topics of the workshop include:

• Model improvement, model development, and common issues with CCMI-1 simulations,
• Process-oriented and observation-based evaluation of the chemistry, dynamics, radiation, and transport in the CCMI-1 simulations,
• Emergent constraints for the evaluation of CCM projections,
• New observations and approaches for improved model evaluation,
• Emission-dependent projections of air quality and impacts on climate/meteorology (and viceversa),
• Emission-dependent projections of the ozone layer and impacts on climate (and vice-versa),
• Effects of stratospheric changes on tropospheric climate and chemistry (and vice-versa),
• Dynamics and chemistry of the Asian monsoon.

Workshop Format:
The meeting will include invited and contributed oral presentations, poster sessions, and breakout-groups focusing on relevant workshop topics.

Stratospheric geoengineering impacts on El Niño/Southern Oscillation. By C.J. Gabriel and A. Robock in Atmospheric Chemistry and Physics Discussions.

Earth’s climate changes globally partly because of its inherent nature and partly because of anthropogenic effects. The middle atmosphere is an important component of the earth climate system that exhibits global cooling in response to the increase in greenhouse gases, and in which the ozone layer can be substantially destroyed leading to the formation of the Antarctic ozone hole. Recent developments in observational techniques and the extension of observational networks have enabled the capture of atmospheric phenomena concurrently over a wide range of temporal and spatial scales. In addition, global numerical models, including coupled climate models and chemistry climate models, in which data assimilation techniques are implemented, are being extended to higher-altitude regions with greater horizontal and vertical resolutions. These developments allow the examination of atmospheric phenomena over a wide range of temporal and spatial scales in terms of their interactions and momentum/energy budgets. Such observations and models generate considerable amounts of data; thus, methods of data analysis are becoming increasingly important and “data-centric” science needs to be pursued. In parallel, new theories that can treat various phenomena seamlessly and three-dimensionally are needed, and those able to describe inductive elucidated structures are being constructed. These circumstances compel us to organize this symposium in order to review the latest research regarding the whole atmosphere, particularly focusing on the middle and upper atmosphere, and to discuss the direction of future endeavors.

Call for Papers

Changes in water availability and quality are occurring mainly as consequences of global and local changes including environmental factors, climate change and human-induced changes. Science-based knowledge to assess water resources over a range of scales in space and time is essential to develop methodologies for water resources assessments to improve sustainable water management practices. Linked to the dynamic assessment of water resources is the ability to provide reliable seasonal predictions of water availability and water quality.

Important research efforts focus on issues such as possible changes or intensification of the hydrological cycle, predictions of freshwater availability under climate change, and the ability to predict the variations of global and regional hydrological processes and water resources. The capability for dynamic water resources assessment linked to seasonal and inter-annual variations of the water balance serves as a basis for interaction with water managers and policy makers at regional and national scales.

The conference is meant to provide a platform for scientists and practitioners to exchange their views on monitoring, assessment and prediction of key variables for water management.

Target Group

The conference aims to reach scientists and water managers actively involved in world water balance research, as well as the development and application of new approaches to water resources assessments and decision-making in water policies and water management. Demand driven-applications to meet requirements of the target group are expected to cover improvements in the observation of the elements of the world water balance, methods for water resources assessments, and the predictability of world and regional water balances. Likewise, quantifiable impacts of changes of the temporal and spatial availability of water resources for integrated water resources management practices will be addressed.

Call for Papers

If your domain of expertise is in one or more of the thematic topics, you are invited to submit an abstract in English language of not more than 500 words to the conference secretariat ()

Abstract submission deadline: 31 March 2015

Description

The workshop is jointly organized by the WCRP Working Group on Coupled Modelling (WGCM) and the European Commission FP7 project EMBRACE (Earth system Model Bias Reduction and assessing Abrupt Climate).

The workshop has three primary aims; following the format of the WCRP CMIP5 model analysis workshop held in 2012, to present and discuss:

• Multi-model CMIP5 analyses taking advantage of the large suite of CMIP5 experiments
• Earth system model improvements that help reduce systematic biases and/or increase the realism of models in terms of climate change response.
• The main aims of CMIP6, in particular presentations of CMIP6-Endorsed Model Intercomparison Projects (MIPs).

The workshop will be structured around the three scientific questions:

1. How does the Earth system respond to forcing?
2. What are the origins and consequences of systematic model biases?
3. How can we assess future climate change given climate variability, predictability and uncertainty in scenarios.

Workshop approach

Short-presentation/poster format

The workshop will consist of a series of half-day sessions. Each session will begin with presenters in that session given a 3 minute time slot to show no more than one slide summarizing the main conclusions of their poster. The rest of the half-day session will consist of viewing posters of that session.

Participation is limited by the size of the venue (~150 people) and format of the workshop.
