DLR Conference on Climate Change 2018 – Atmospheric Research for Understanding and Mitigating Climate Change

DLR Conference on Climate Change 2018 – Atmospheric Research for Understanding and Mitigating Climate Change

in collaboration with the United Nations Office for Outer Space Affairs (UNOOSA)

Cologne, Germany, 17-19 April 2018, www.dlr.de/ccc2018

This scientific conference aims to bring international scientists, space agencies and interested parties together with United Nations entities such as UNOOSA, UNSPIDER, UNFCCC, WMO and GCOS and thus provide a discussion forum to elaborate on the substantial challenges faced in atmospheric climate research. By encouraging an open exchange of ideas we hope to facilitate the implementation of suitable measures to support the requirements as outlined in the Paris Agreement.

During the conference, invited oral presentations will be given by renowned experts in the field. In addition, there will be a dedicated poster session for contributed papers.

Please visit www.dlr.de/ccc2018 for further information.

Online registration is now possible. Online registration closes on April 3, 2018. The deadline for abstract submission for poster presentations is March 15th, 2018 . Please note that hotel accommodation at reduced rates is available until March 6th, 2018.

The International Space Science Institute (ISSI) in Bern, Switzerland, and ISSI-BJ in Beijing, China, invite proposals for establishing International Teams to conduct on their premises research activities in Space Sciences, based on the interdisciplinary analysis and evaluation of data from spacecraft, and possible integration with ground data and theoretical models. The Call is open to scientists of any nationality, actively involved in the following research fields:

1. Space Sciences (Magnetospheric and Space Plasma Physics, Solar-Terrestrial Sciences, Solar and Heliospheric Physics, Planetary Sciences, Astrobiology, Cosmology, Astrophysics, and Fundamental Physics in Space)

2. Earth Sciences using space data

Deadlines for proposals:

1st Announcement: Workshop: “Tri-MIP-Athlon”

A Joint AerChemMIP / RFMIP / PDRMIP Workshop in Support of CMIP6

Dates: 11-15 June 2018

Venue: University of Reading, Reading, UK

Theme: New Science opportunities from CMIP6 multi-model forcing response experiments.

The Joint workshop will focus on the use of multi-model experiments to quantify the effective radiative forcing driven by changes in composition and the consequent climate responses. Data from idealised experiments are already available from PDRMIP. For the first time in CMIP, forcing data from all the CMIP6 climate models will be generated under the RFMIP protocols, and further broken down by forcing component in RFMIP and AerChemMIP.

Workshop goals:

  1. To discuss RFMIP and AerChemMIP experiments and plan analyses
  2. To discuss the scientific results coming from PDRMIP and related analyses and the potential for new science from CMIP6 on composition, forcing and response.

This workshop will be of interest to all those analysing/planning to analyse model forcing and response. Attendance from modelling centres contributing to RFMIP or AerChemMIP experiments is encouraged.
