Paleoclimate data synthesis and analysis of associated uncertainty (BG/CP/ESSD inter-journal SI)
10 Oct 2017–30 Jun 2019 | Guest editors: A. Paul, C. Ohlwein, and L. Jonkers | Information


Paleoclimate data provide unique insights into climate dynamics across a range of timescales. Importantly, paleoclimate data are the only means of evaluating and constraining climate models under boundary conditions different from today and the recent past. However, most paleoclimate data are presently archived in a fragmented and non-standardized way, necessitating synthesis efforts in order to allow meaningful analysis of spatio-temporal climate dynamics and data-model comparison. Moreover, paleoclimate data are inherently uncertain since they are based on indirect evidence (proxies) and associated with chronological error, requiring rigorous uncertainty analysis to separate signal from noise and to make full use of paleoclimate data syntheses.

This special issue provides a platform to present paleoclimate synthesis products, to review the current state of proxy uncertainty analysis, as well as to present new developments. The issue is organized within the paleoclimate data synthesis working group of the PALMOD (http://www.palmod.de/) project, which focuses on the past 130,000 years. However, this is an open submission issue and we explicitly invite contributions from across the paleoclimate community describing synthesis methods and results from any kind of archive and/or parameter. We welcome contributions presenting paleoclimate synthesis products and their analysis across timescales, with regional or global focus and both time slice and transient approaches as well as conceptual contributions to proxy data uncertainty analysis (theoretical, empirical, Bayesian).

The 10th International Carbon Dioxide Conference (ICDC10) and the 19th WMO/IAEA Meeting on Carbon Dioxide, other Greenhouse Gases and Related Measurement Techniques (GGMT-2017) (AMT/ACP/BG/CP/ESD inter-journal SI)
01 Oct 2017–30 Sep 2018 | Guest editors: H. Fischer and I. C. Prentice | Information


The International Carbon Dioxide Conference (ICDC) is the single largest conference organized by the global research community every four years to present the latest scientific findings on the science of the carbon cycle and its perturbation by human activities. The ICDC10 in 2017 is the 10th anniversary conference. It covers fundamental science advancement and discovery, the generation of policy relevant information, and observational and modeling approaches. ICDC10 brings together scientists from different disciplines to work towards an integrated view on the global cycle of carbon in the Earth system.

The main themes of the conference are as follows:

  1. The contemporary carbon cycle
    • Trends, variability, and time of emergence of human impacts
    • Emerging approaches and novel techniques in observations
  2. The paleo-perspective: patterns, processes, and planetary bounds
  3. Biogeochemical processes
    • Process understanding and human impacts
    • Coping with complexity: from process understanding to robust models
  4. Scenarios of the future Earth and steps toward long-term Earth system stability

GGMT-2017 is a key conference on measurement techniques for accurate observation of long- lived greenhouse and related gases, their isotopic composition in the atmosphere relevant for climate change, and global warming research findings. The biannual meeting, known as the WMO/IAEA Meeting of Experts on Carbon Dioxide, Other Greenhouse Gases and Related Tracer Measurement Techniques, is to be held for the 19th time in 2017.

Main topics:

  • Developments of the GHG networks
  • CO2 observations (measurement techniques and calibration)
  • Non-CO2 observations (measurement techniques and calibration)
  • Isotope measurement and calibration
  • Emerging techniques
  • GHG standards and comparison activities
  • Integration of observations, data products and policy

The special issue is open for papers that emerged from ICDC10 and GGMT-2017 conference contributions.

The Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) (ESD/ACP/CP/GMD inter-journal SI)
15 May 2017–30 Apr 2019 | Coordinators: C. Timmreck, M. Khodri, and D. Zanchettin | Papers are handled by CP editors | Information


Volcanic eruptions are one of the major natural factors influencing climate variability at interannual to multidecadal timescales. However, simulating volcanically forced climate variability is a challenging task for climate models and one of the major uncertainties in near-term climate predictions. The Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) is an endorsed contribution to the sixth phase of the Coupled Model Intercomparison Project. This multi-journal special issue on VolMIP aims at collecting relevant research results obtained within the VolMIP framework, and specifically concerning different aspects of the radiative and dynamical climatic response to volcanic forcing, detailed description of effects of different implementation of volcanic forcing in current climate models, aspects concerning the dynamical and chemical atmospheric response to volcanic aerosols simulated by global aerosol models, and comparison between reconstructed and simulated climate evolution after major eruptions. Articles in the special issue should contain the following statement: "This article is part of the special issue "The Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) (ESD/GMD/ACP/CP inter-journal SI)". It does not belong to a conference."

Paleoclimate Modelling Intercomparison Project phase 4 (PMIP4) (CP/GMD inter-journal SI)
10 Jan 2017–31 Dec 2018 | Guest editors: M. Kageyama, P. Braconnot, S. Harrison, J. H. Jungclaus, B. L. Otto-Bliesner, and M. F. Loutre | Information


The Paleoclimate Modelling Intercomparison Project (PMIP) has been set up to provide a mechanism for coordinating paleoclimate modelling and model evaluation activities, to understand the mechanisms of climate change and the role of climate feedbacks in these changes. PMIP is now in its fourth phase: PMIP4. Five PMIP4 experiments have been proposed within the framework of the CMIP6 exercise. Other periods and sensitivity experiments are also planned to assess climate sensitivity, changes in hydrology, long-term trends and interannual to millennium variability. This special issue is devoted to the description of the design of the PMIP4 experiments, of data syntheses to which model results can be compared, and to papers analysing single or multi-model results from PMIP4 and CMIP6 experiments. Papers can either be submitted to GMD (model and simulation descriptions, data syntheses in support of the experimental design or of model-data comparisons) or CP (in-depth analyses, multi-model analyses, model-data comparisons).

PlioMIP Phase 2: experimental design, implementation and scientific results
01 Aug 2015–31 Dec 2018 | Guest editors: Alan Haywood, Aisling Dolan, and Wing-Le Chan | Information


The Pliocene Model Intercomparison Project (PlioMIP) Phase 2 is a strategic international climate modelling initiative that compares model predictions and uses climate models and geological proxy data together to better understand climate and environments of the late Pliocene. PlioMIP2 is also exploring the relevance of the Pliocene in the context of future climate change. We welcome submissions from registered participants that document the results of climate model simulations for the Pliocene using the PlioMIP2 protocols. These simulations will facilitate analyses of the dynamics of Pliocene climate and compare climate model results with each other. In addition comparisons of climate model results with proxy data will be presented.
