A report in response to a request by the Committee on Space Research of the International Council for Science to prepare a roadmap on observation and integrated Earth-system science for the coming ten years. Its focus is on the combined use of observations and modelling to address the functioning, predictability and projected evolution of interacting components of the Earth system on timescales out to a century or so. It discusses how observations support integrated Earth-system science and its applications, and identifies planned enhancements to the contributing observing systems and other requirements for observations and their processing. A set of concluding discussions covers general developmental needs, requirements for continuity of space-based observing systems, further long-term requirements for observations and other data, technological advances and data challenges, and the importance of enhanced international co-operation.

Tropical Atlantic climate recently experienced pronounced shifts of great socio-economic importance. The oceanic changes were largest in the eastern boundary upwelling systems. African countries bordering the Atlantic strongly depend upon their ocean-societal development, fisheries, and tourism. They were strongly affected by these climatic changes and will face important adaptation challenges associated with global warming. Furthermore, these upwelling regions are also of great climatic importance, playing a key role in regulating global climate. The 2016 TAV Conference will include sessions on: 1) Oceanic and atmospheric processes affecting physical-biogeochemical interaction and climate; 2) Mechanisms and simulation of tropical Atlantic climate variability; and 3) Towards realizing socio-economic benefits of climate prediction in the Tropical Atlantic for marine ecosystems, fisheries, and continental climate. Abstract submission closes 1 September 2016. For more details see the conference website.

This workshop is intended to facilitate the more rapid advance of development of coupled data assimilation methodologies to improve weather and climate predictions and reanalyses. The workshop will cover methods for coupling of data assimilation methodologies between the atmosphere, ocean, land-surface, sea-ice, aerosols, atmospheric chemistry, and more, including weak coupling (coupling of the forecasts providing the background forecasts) and strong coupling (coupling of the state estimation as well). The workshop will also consider which observations are particularly important to advance coupled assimilations. The workshop will include overview presentations by selected invited speakers, 15-minute oral presentations, posters, discussion of the key scientific and technical challenges, and breakout groups to list the key issues and to formulate recommendations for how collaboration facilitated by the WMO can advance the state of the science more rapidly. The deadline for abstracts is 11 September 2016. For more see the workshop website.

The Tropical Pacific Observing System (TPOS) aims to meet the observational, experimental, and operational needs of today and the future. The purpose of the TPOS 2020 project is oversee the transition to a more resilient and integrated observing system to meet the identified gaps as well as future needs as they are identified. A (revised) draft, now called the "First Report" (second and final reports will come in 2018 and 2020) can be downloaded from the TPOS 2020 website. While still a draft, to be finalized at the end of this year, it is now a public document that can be circulated.

Also see the link on the TPOS 2020 website to download the comment spreadsheet for this second draft. You are encouraged to comment on the revision; please use the spreadsheet, which makes it far easier to keep track of comments and responses. Every comment gets a specific response, and these will all be posted publicly (both drafts, no names on comments). In order to make final decisions on this report at the Steering Committee meeting in October, all comments are due by 23 September 2016.

We appreciate your help in sharing the report with other stakeholders of TPOS observations.

INARCH participants and their research teams are invited to participate in the second GEWEX INARCH Workshop. This workshop will bring scientists together to explore and discuss specific issues in mountain snow and ice hydrology highlighted after the inaugural INARCH workshop in Kananaskis in October 2015. The workshop is open to all scientists contributing directly or indirectly to the INARCH GEWEX crosscut project. Early-career scientists are encouraged to participate.  If you wish to become an INARCH participant please contact John Pomeroy with an expression of interest and description of what your contribution to the project might be.

Three main topics will be covered by the Workshop:

• Atmospheric downscaling for mountain snow and ice hydrology modeling
• Availability and suitability of surface observations and spatial observations from mountain observatories (including discussion of the mountain observations journal special issue)
• Climate sensitivity numerical experiments – results from numerical diagnostic experiments using the cryospheric and hydrological response of mountain catchments to various representations of a changing climate

This 3-day meeting will include 2 days of presentations/discussions and a 1-day optional field trip to one of the INARCH observatories in the French Alps (to be determined). It will take place at the Laboratory of Glaciology and Environmental Geophysics (Lliboutry Conference Room, LGGE main building), on the campus of University of Grenoble, Grenoble, France. There will be no meeting registration cost and lunch will be provided (including the lunch during the optional field trip). We anticipate being able to provide partial travel support to participants for travel and accommodation (especially to early career scientists). Please contact the organizing committee if you wish to request this support.

Participants will make their own travel arrangements to Grenoble. Information regarding transportation is available on the 'How to find the LGGE' webpage.

Interested participants need to provide an expression of interest of attending or presenting by emailing Vincent Vionnet. If you wish to make a presentation please indicate the provisional title of your talk. An abstract will be requested later. Please also mention whether you intend to participate in the optional field trip.

The Scientific Committee thanks you for considering this workshop and thank the Local Organising Committee for their work in making arrangements and hosting it in France this year.

The authors identify human and natural contributions to the observed Indo-Pacific warm pool (IPWP) changes since the 1950s by comparing observations with climate model simulations using an optimal fingerprinting technique. Greenhouse gas forcing is found to be the dominant cause of the observed increases in IPWP intensity and size, whereas natural fluctuations associated with the Pacific Decadal Oscillation have played a smaller yet significant role.
